Much is made of Personal Electrical Safety, yes it is of prime importance, however often Personal Safety takes precedence over concerns of fire safety and it gets left out of the Risk Assessment. As a result, little consideration is taken to reduce fire hazards in particular fire hazards concerning power boards and extension Leads. Over the years there has been an increase in the number of fires caused by electrical power-boards and leads. The origin of these fires has been identified as the improper use of electrical leads, and incorrect placement of power-boards.

By and large the most prevalent electrical fire faults have been attributed to the overloading of multiple outlet power-boards by electrical appliances which exceed the maximum rated output of the boards. This can cause the power-board to overheat, melt and catch fire. Included is the practice of placing double adaptors on power-boards to increase the number of power outlets, and the piggybacking of double adaptors on power points. These are extremely dangerous practices.

Most common Power-boards are designed with a 10 amp maximum rating and may incorporate up to eight power outlets. However, some electrical appliances such as Urns, Heaters, Toaster Ovens etc, can draw up to 4 amps for each item plugged in , making it relatively easy to exceed the power-board rating if all the outlets were in operation.

It is important that all your electrical appliances are used strictly according to manufacturer’s recommendations and ensure that any electrical appliances used individually or as a group do not exceed the power-boards maximum rating.

So What Can I do about it? (Prevention is the only way, cure is too late!)

• Ensure power-board rating is not exceeded by the appliances attached to the power-board.
• Do not use double adaptors in the Workplace (power boards cost just a little bit more and offer overload protection and more outlets)
• Never Chain from one power board to another to increase the number of power points.
• Conduct regular inspections of power-boards for visual damage or discolouring.
• If you suspect that a power-board is faulty, immediately take it out of service or replace it.
• Turn off powerboards at the power point when not in use.
• Ensure adequate ventilation around the power-board to prevent overheating.
• Use RCD protected Power Boards where fixed RCD protection is not available.

And don’t forget your Electrical Appliances.

• Provide adequate ventilation space around electrical appliances to allow heat to vent freely.
• Never operate electrical appliances in damp or wet areas.
• Not only turn electrical appliances off at their switch, but also to turn off the power point
• By taking these simple precautions the risk of fire starting from the use of electrical equipment can be minimised. Remember, above all, the best protection for you and your co-workers/employees is to have a properly installed and operating Smoke Alarm.

Update your Fire Emergency Plan and ensure that all staff know where to evacuate and assemble

You may think that a little knowledge of Electrical theory or perhaps doing some experimental wiring around your house makes you an Experienced and Knowledgeable technician. Well not so!: Being a licensed Electrician requires a great knowledge of wiring distribution systems and wired devices that can only be taught in a safe environment with qualified Instructors. On top of this being a qualified Electrician also requires a good understanding of SAA wiring rules known as the standard AS/NZS 3000:2007.

The Standard sets out requirements for the design, construction and verification of electrical installations. These requirements are intended to protect persons, livestock, and property from electric shock, fire and physical injury hazards that may arise from an electrical installation that is used with reasonable care and with due regard to the intended purpose of the electrical installation.

Electrical installation work in all states and territories can only be undertaken by licensed electricians or electrical contractors. In addition, a person or business must not carry on or offer to carry on any electrical contracting work unless they are registered or licensed electrical contractors in accordance with the Electrical Licensing/Registration Scheme in that particular state or territory.

These rules are for the protection of the community – they give you recourse if something goes wrong, and also help to ensure that the electrician you use is qualified and able to carry out a quality job.  Don’t risk electrocution, or worse, by doing it yourself – use a professional.

One method of  reducing Electrical hazards is to use a practical approach which in turn engenders a culture of  electrical safety in your Workplace. One such approach is called the

S A f e r approach

See it (hazard identification) Record the Hazard , its location and briefly/accurately describe the reasons why it is a hazard !

Assess it (risk assessment) Assess the likelihood that a person will be hurt,
how badly they will be hurt, how they could be hurt, how much, how long
and how often a person is exposed to the hazard.

Fix it (risk control) How are the hazards going to be controlled?
If elimination of the hazard is not possible, other controls should be
implemented to reduce potential risks.  These controls may include the use
of Residual Current Devices (RCDs). Other controls that should be considered are: safety switches, regular monitoring, record keeping, the testing of electrical equipment and fixed wiring, safe systems of work and personal protective equipment.

Evaluate once the most appropriate fix has been selected and implemented.
It is important to evaluate whether the fix has been successful in controlling
the hazard. Simply re-assessing the risk again will establish if the hazard has
been eliminated or reduced.

Review after a period of time and if the work environment or work practices change. A review of this process is needed to continually control the hazard.

WINTER IS NEARLY HERE!

Time to pull on the Uggies and put those warm Trackie Dacks on (Tracksuit/Sweat suit) and get out you favorite electrical heating appliance… aah Cosy, Warm …and Safe !?! (well you’d hope)

Statistics show that sales of electrical appliances increase during May. The first winter like chill and we are down at the shops looking for the easiest  and sometimes the cheapest way to warm ourselves… Then at that point; it is a Good time to review safety tips on buying and using electrical appliances.

Large electrical appliances are a major cause of electrocutions. Make sure appliances are purchased
from reputable dealers and have been certified by Australian standards.  The introduction of cheap/counterfeit electrical appliances products into the marketplace is on the rise. Appliances must comply with the minimum safety requirements contained in Australian Standard AS/NZS 3820:1998. Here below is a tick mark to look for on all approved equipment.

For portable heaters used frequently  during colder months. Following manufacturers’
instructions is the first step in avoiding electrical hazards.

Power boards and extension cords do not provide more power, but increase access to electrical outlets. As we try to meet 21st century power needs in homes and buildings with too few outlets to meet needs, our use of power boards and extension cords increases. Use of  improperly rated extension cords and power boards is among the causes of many  electrical fires each year.

APPLIANCES, ELECTRONICS AND  LIGHTING

If an appliance repeatedly blows a fuse, trips Safety Switch / breaker or has given you an electrical shock, immediately unplug it and have it repaired or replaced. Look for cracks or damage in wiring, plugs and connectors.

Use surge protectors to protect expensive electronics.

Check the wattage of bulbs in lamps and light fixtures to make sure they are the correct wattage. Replace bulbs that have a higher than recommended wattage;
they are a fire hazard. Make sure bulbs are screwed in securely because loose bulbs can overheat.

Halogen lamps operate at high temperatures. Make sure halogen bulbs do not come into contact with curtains, clothing or other flammable materials.

ELECTRIC BLANKETS and SAFETY

Electric blankets should be rolled when stored away. Folding an electric blanket can damage element wires within the blanket.
When using a blanket for the first time after storage, lay it flat on the bed and check for hot spots as it heats up. Only add sheets once you are sure the blanket will operate safely at a maximum temperature.
Electric blankets that are not properly maintained can cause fires.
Avoid using double adaptors or power boards wherever possible.
Older electric blankets might be damaged and may not have the safety features of modern blankets, so consider replacing them.

To avoid disaster, children need to be aware of  improper uses of electric items and the consequences of unsafe behavior. Practicing safe electrical habits early in life will be valuable through out adulthood.

How do surge protected power boards work ?
At first glance a surge protected power board operates like any other Power Board. It shows its ability at that moment when too much voltage gets passed along the transmission line , the surge protected board lets only a ‘safe’ amount through to the connected equipment. The rest it channels into the electrical outlet’s ‘earth’ and safely dissipated into the ground.
When a surge occurs at a certain level above normal voltage, a component built into the surge protected power board becomes conductive and starts to carry the excess electric current back down through the ground wire, so the damaging high voltage doesn’t reach connected equipment. Once the surge ends, that protective component resumes its ‘dormant’ stage of being non-conductive. It’s a bit like an electrical version of a pressure valve.
Australian domestic wiring is designed for a standard voltage of 230–240 volts. If the voltage goes too far above that, it can damage electronic equipment, which usually has many sensitive components. If excess voltage lasts for a very brief time (1–2 nanoseconds) it’s called a spike. If it lasts longer it’s called a surge. Even though a spike or surge can be so brief their duration is measured in nanoseconds, they can still cause damage to sensitive components. It is vitally important to protect sensitive business equipment, Computers, printers, photocopiers etc these items of equipment are sensitive to Surges in voltage.
So what sort of a Surge Protected Board should you Buy ?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
Response time – Surge protectors don’t kick in immediately; there is a very slight delay as they respond to the power surge. A longer response time tells you that your computer (or other equipment) will be exposed to the surge for a greater amount of time. Look for a surge protector that responds in less than Ten nanoseconds.
It is best to look for a Surge protected board with an indicator light that tells you if the protection components are functioning. Eventually the protection component will burn out after continual power surges, but the board will still function as a power connection. Without an indicator light, you have no way of knowing if your protector is still functioning properly.
Other important features may include ?
Building wiring status indicator: Detects potentially dangerous wiring problems in the wall outlet.
Circuit breaker: Protects the surge board from overload by connected devices drawing too much current.
EMI noise filtration: This reduces or eliminates line noise (electrical interference).
Other connections: Surge protected sockets for coaxial cable, modem or Ethernet network, all of which can also conduct high voltage that can damage connected devices.
Outlet spacing: Allows more room for one or more devices that use a transformer block.
Sockets: Check the number of mains power sockets available, usually from four to eight.

Competency requirements for those carrying out inspection and testing of electrical equipment

Inspection and testing of electrical equipment must be carried out by a person who has acquired, through training, qualification or experience, the knowledge and skills to carry out the task (i.e. be a ‘competent person’). Inspection and testing of electrical equipment must be carried out by a competent person who has the relevant knowledge, skills and test instruments to carry out the relevant inspection and testing. The person carrying out any testing of electrical equipment should also be competent to interpret the test results of any equipment they use. For example, a person carrying out testing under AS/NZS 3760:2010 must be:

• a licensed or registered electrician (whichever applies), or
• in some jurisdictions, a licensed electrical inspector, or
• a person who has successfully completed a structured training course and been deemed competent in the use of a pass-fail type portable appliance tester and the visual inspection of electrical equipment.

The training should be designed to ensure, so far as is reasonably practicable, that on completion successful participants:

• can use the relevant test equipment safely and effectively
• understand electrical risks and appreciate the role that inspection and testing plays in ensuring electrical safety
• understand AS/NZS 3760:2010 and AS/NZS 3012:2010 (if testing equipment for construction or demolition sites)
• understand the legal requirements relevant to the work.

Some kinds of electrical testing must only be carried out by a licensed electrician or electrical inspector under local electrical safety laws. For example, testing requiring the dismantling of electrical equipment should only be carried out by a licensed electrician.

Additional or different competencies may be required for more complex kinds of testing outside the scope of AS/NZS 3760:2010.

If in doubt, advice should be obtained from a person qualified and experienced in electrical equipment testing, for example an electrician, electrical contractor, electrical inspector, specialist testing provider or relevant regulator.

Safety Switch 101

The best single safety investment you can make for your Workplace or dwelling is to buy a Safety Switch. Installing a Safety switch is the most effective method of preventing injury or death caused by electric shock. A safety switch works by detecting tiny differences in current through electrical wiring, and it can detect a potential path to earth. Take the example of a person holding a faulty appliance that has an electric charge thereby providing a path to earth. A truly effective Safety Switch will detect that leaking electrical path and shut all the power down in mere milliseconds, quite often before the sensation of electrocution is felt, thereby preventing a harmful or potentially fatal electric shock.  Safety switches are Electro-mechanical devices and over time can be subject to failure. They should be tested regularly to make sure they are in working order.

Safety Switches can be prone to trip under certain conditions… There are a number reasons why a safety switch will trip. The Top 5 reasons are:

An Appliance Fault

When an appliance becomes damaged or develops a fault, it may start to leak excess electrical current. This excess current will be detected by the safety switch and cause it to trip. The easiest way to determine if this is the problem is by unplugging all electrical appliances at the power point, resetting the safety switch and then reconnecting the appliances one by one until the faulty appliance can be identified. Always use caution when dealing with possible faulty appliances and if in doubt contact an electrician.

Intermittent or Nuisance Tripping

As the amount of electrical appliances we have in our home increases, so does the likelihood of Nuisance Tripping. If there are a large number of appliances plugged in to the home at one time and a small amount of current leaks from each, the current adds up to become more substantial. This may mean that the safety switch is continuously on the verge of tripping. If there is the tiniest change in electrical current from the electricity company this can push the switch to its limit causing it to trip. This can become more of a problem in older homes where the electrical wiring is not in good condition. Limiting the amount of appliances plugged in at one time can help minimize this type of tripping.

House Wiring Fault

Faulty wiring poses the most threat to our safety and presents the worst fire risk. Fortunately, a safety switch dramatically reduces these risks. All wiring deteriorates over time and can become dangerous, so older houses are obviously more at risk. A safety switch will detect any fluctuation in electrical current caused by damaged wiring and trip, cutting off electricity immediately and stopping the wiring from burning out. A qualified electrician can assess your electrical wiring and may suggest repair or replacement.

Faulty Safety Switch

Sometimes the cause of a safety switch tripping can be the switch itself. As with any electrical appliance, a safety switch can become defective with age or mistreatment. Safety switches should be checked every six months to ensure they are working effectively. A qualified electrician can offer advice on how to do this, or do it for you if you are unsure.

Electrical Storm

An Electrical Storm can also be the cause of a safety switch going off. When lightning strikes your home, power lines or a power station it may cause a power surge which can cause a safety switch to trip. If this occurs, it is best to wait until the storm passes before resetting the switch. If in doubt always consult an electrician.

Without the right safety equipment and safety precautions, electricity can be deadly. Always check with an electrician if you are unsure why your safety switch has gone off.

Electrical Safety Switch Tripping possibilities

Electrical Safety Switches  are RCDs ( Residual Current Devices)  that remove the supply to an electrical circuit when the circuit under protection has detected a leakage to earth. The RCD/Safety Switch responds in mere mili -seconds; avoiding an unsafe condition and thereby potentially preventing electrocution or Fire hazard.

Possible Causes Of Safety Switch/RCD Tripping

Faulty appliance – unplug all electrical appliances, does the RCD reset OK? If the RCD resets OK plug the appliances back in one at a time. Reset the RCD as you plug each appliance back in to find the faulty appliance.

Items with motors or pumps starting – many items with motors or pumps, for instance showers and pond pumps, cause momentary electrical spikes that are big enough to trip RCDs. Seek advice from a qualified electrician.

Older washing machines – aging washing machine heating elements can cause momentary electrical spikes that are big enough to trip RCDs.

Certain wash cycle phases – some cycles of the washing machine, for instance the spin cycle, can cause momentary electrical spikes that are big enough to trip RCDs.

Certain dishwasher cycles – some parts of the dishwasher cycle draw a lot of current, a faulty component, for instance the motor, can trip an RCD.

Overloading a washing machine – too many items in a washing machine can cause certain wash cycles, for instance the spin cycle, to trip an RCD.

Fridges and freezers cooling – the fridge or freezer cooling motor starting.

Turning an heating element on after a long time of being off – moisture in heating elements can trip an RCD, for instance in a sun bed or electric fire. Try resetting the RCD a few times so that the heating element can cause the moisture to evaporate.

Moisture in outside electrical distribution boxes – remove the supply and dry the distribution box. Check the weather seals have not perished.

Moisture in outside electrical sockets – remove the supply and dry the electrical socket. Check the weather seals have not perished.

De-frost timer on a fridge or freezer – a faulty defrost element on a fridge or freezer can cause ‘nuisance’ RCD tripping.

Water heating elements – faulty water heating elements can cause nuisance RCD trips when thethermostat tells them to heat the water.

Moisture in wiring – moisture in the electrical wiring is a common cause of RCD trips. Have you just emptied a bath? Taken a shower? Is it raining – rain can get into the electrical wiring under the floors or in the loft.

As you may have found this list contains certain  conditions that may give clue to an RCD tripping. In most cases this concerns appliances or situations that involve at least one or a combination of  three conditions 1) Moisture leaking electricity to earth in the appliance or premises wiring. 2) A heating element that is either faulty or drawing sudden electrical surges. 3) An appliance with an electric motor that is either faulty or drawing sudden electrical surges.

If you have trouble sourcing constant or intermittent RCD/Safety Switch Tripping then Contact us and we can send a Qualified Electrician around to check it they can source and fix it on the spot.

Power board safety advice

The practice of overloading power boards with many appliances (particularly large current devices,heaters, urns, portable air conditioners)  and adding other power boards or adapters  to increase capacity are undoubtedly the  major cause of fire at the Home and in the Work Place.

DON’T:

• Plug in high power devices into power boards, ie Fan heaters, It is far safer to connect these appliances to a wall outlet
• connect double adaptors to power boards
• cascade a chain of power boards together, either double up your power outlet on the wall or get another outlet installed.
• use damaged power boards
• use power boards in wet areas such as Laundries and Bathrooms
• use power boards as a substitute for permanent power outlets
• use power boards in dirty or dusty areas use power boards with shutter covers in these areas.

DO:

• always ensure that plugs fit firmly in the power board sockets
• regularly check the power board for any signs of damage, cracking and discolouration
• keep power boards out of the reach of children and pets
• allow for adequate ventilation around the power board.
• make sure you have an RCD or safety switch protected circuit that is supplying the power board
• consider installing a permanent power outlet so you do not need to use a power board.
• Have your appliances and power boards regularly inspected, tested and tagged, particularly if you are a business, charity or public organisation with Workers/Volunteers/General public using Power boards and appliances.

Using extension cords safely

DO:

• always use an extension cord that has earth, active and neutral wires and a 3-pin plug – never use a 2 core flex (two wires only) as an extension cord.
• ensure that the cord is fully unwound so it doesn’t overheat

DON’T:

• join extension cords together. If you need an extension cord longer than 25 metres ask a licensed electrical contractor to install a general purpose power point.
• use extension cords in wet weather or where they could contact water. If your extension cord gets wet, switch it off, and discard it.
• place extension cords where they can be walked on or driven over. This may damage the cord and expose live wires. You can mount your extension cord on a fixture with a height of 2.5m (8ft) using tape or cable ties.
• overload extension cords. The maximum load on an extension cord should not exceed 2,300 watts (In Australia that is nominally 10amps at 230 volts supply). Check the labelling on the extension cord to see how many watts it is rated at. Also consider using extension cords are labelled Construction Grade in outdoor and potentially hostile environments.

Working near Power lines here in South Australia

Performing work in close proximity to overhead power-lines or underground power cables can be a hazardous operation. Fatalities and injuries occur every year as a result of unsafe work practices when working near overhead power-lines. All machinery operators and other workers conducting work near overhead power-lines should also be aware of their safety obligations and adopt safe work practices

Practice safe work habits

Before work commences a Hazard Assessment must take place. It is an important task to Identify all electrical hazards, assess the risks, establish control measures and review these periodically. Control measures may include, but may not be restricted to:

• applying appropriate signage at least 8 to 10 metres either  side of power-lines and using visual indicators such as tiger tails fitted to the power-lines
• Using ground barriers, where appropriate
• Informing workers of required work practices.
• Ensure operators are aware of the height of their machinery in both stowed and working positions.
• Lower all machinery to the transport position when relocating. Work away from power-lines, not towards them.
• Exclusion zones:  If the work you and your staff are planning has the potential to encroach into power-line exclusion zones, you should contact SA Power Networks for advice on doing the job safely.
• Contact  SA Power Networks about placing identifiers on power-lines and power poles at your worksite and any further control measures.

WINTER IS NEARLY HERE!

Time to pull on the Uggies and put those warm Trackie Dacks on (Tracksuit/Sweat suit) and get out you favorite electrical heating appliance… aah Cosy, Warm …and Safe !?! (well you’d hope)

Statistics show that sales of electrical appliances increase during May. The first winter like chill and we are down at the shops looking for the easiest  and sometimes the cheapest way to warm ourselves… Then at that point; it is a Good time to review safety tips on buying and using electrical appliances.

Large electrical appliances are a major cause of electrocutions. Make sure appliances are purchased
from reputable dealers and have been certified by Australian standards.  The introduction of cheap/counterfeit electrical appliances products into the marketplace is on the rise. Appliances must comply with the minimum safety requirements contained in Australian Standard AS/NZS 3820:1998. Here below is a tick mark to look for on all approved equipment.

For portable heaters used frequently  during colder months. Following manufacturers’
instructions is the first step in avoiding electrical hazards.

Power boards and extension cords do not provide more power, but increase access to electrical outlets. As we try to meet 21st century power needs in homes and buildings with too few outlets to meet needs, our use of power boards and extension cords increases. Use of  improperly rated extension cords and power boards is among the causes of many  electrical fires each year.

APPLIANCES, ELECTRONICS AND  LIGHTING

If an appliance repeatedly blows a fuse, trips Safety Switch / breaker or has given you an electrical shock, immediately unplug it and have it repaired or replaced. Look for cracks or damage in wiring, plugs and connectors.

Use surge protectors to protect expensive electronics.

Check the wattage of bulbs in lamps and light fixtures to make sure they are the correct wattage. Replace bulbs that have a higher than recommended wattage;
they are a fire hazard. Make sure bulbs are screwed in securely because loose bulbs can overheat.

Halogen lamps operate at high temperatures. Make sure halogen bulbs do not come into contact with curtains, clothing or other flammable materials.

ELECTRIC BLANKETS and SAFETY

Electric blankets should be rolled when stored away. Folding an electric blanket can damage element wires within the blanket.
When using a blanket for the first time after storage, lay it flat on the bed and check for hot spots as it heats up. Only add sheets once you are sure the blanket will operate safely at a maximum temperature.
Electric blankets that are not properly maintained can cause fires.
Avoid using double adaptors or power boards wherever possible.
Older electric blankets might be damaged and may not have the safety features of modern blankets, so consider replacing them.

To avoid disaster, children need to be aware of  improper uses of electric items and the consequences of unsafe behavior. Practicing safe electrical habits early in life will be valuable through out adulthood.

Workplace Power Tool Safety Tips

Introduction:

Power Tools are time saving convenient devices that assist us in building and maintaining our World. However it also contributes to large amount of injuries recorded in Australia every year. Many of these injuries are often easily avoidable and attributed to carelessness, a lack of proper tool maintenance or simply not reading the operating instructions.

Power Tool safety 101

•          Wear safety gear

Always wear the appropriate safety gear, particularly safety eye wear. Flying shards and debris create unpredictable trajectories and a sudden occurrence can not only cause damage to your eyes but force you to loose control of the powered tool you’re operating.

In addition to eye wear, workplace noise is also often overlooked. However the cumulative time of exposure to above normal decibel levels in the workplace can do irreversible damage to your hearing.

Other safety gear such as gloves and appropriate clothing/ safety footwear are just as important, and should be part of formal personnel safety plans.

•          Read the operating instructions

Being unfamiliar with the safe operation of the power is often the cause of power tool injuries. Before using anew power tool ensure you read the operation, safety and maintenance instructions of the particular tool. The key here is to familiarize both yourself and your team with new equipment when it is introduced to the fleet or job. In particular, built in safety devices and kill switches should be highlighted. Remember to also use a RCD power breaker/power board when working with high powered tools.

•          Electrical Safety and Power Tool operation

When workers use portable power tools and electrical leads that are electrically faulty or damaged they may suffer electrical shock, which could result in death, heart problems, internal organ damage or burns. To reduce risk of injury or death, electrical leads and power tools should be visually inspected prior to use, and avoided if equipment appears to have been modified or damaged. Tools should only be plugged into socket outlets that are protected by a residual current device (RCD) or a portable RCD is used.

Cut Lead Exposed wires found on Circular Saw at Warehouse

Workers should ensure power circuits are protected by the appropriate rated fuse or circuit breaker to prevent overloading and potential overheating. Electrical leads should be arranged so they do not run across the floor or ground, through doorways and over sharp edges. Where the lead arrangement is dangerous, lead stands or insulated cable hangers should be used to keep leads off the ground. Leads and tools should never be used in damp conditions unless they are specially designed for use in those conditions. Ensure your Tools are Tested and Tagged regularly to pick up electrical faults and potential hazards.

•          Report all accidents

It’s important to report all accidents and injuries in the workplace. This not only creates a culture of continuous learning, but also helps to future proof against lengthy compensation claims.

In South Australia, It is a legal obligation to notify Safe-Work SA of any work-related injury that requires treatment as an inpatient in a hospital immediately after a workplace  injury (disregarding any time taken for emergency treatment or to get the person to hospital).If you are reporting work-related injuries or incidents to Safe-Work SA the 24 hour Emergency, Dial 1800 777 209.

Fuses,Circuit Breakers and Safety Switches

These devices are found in your Switch board understanding these devices and how to use and maintain them will help  your management and understanding of Electrical Safety in the Workplace.

Primary Overload response devices (Fuses & Circuit Breakers)

Fuses and circuit breakers are built to fail in conditions of excess current which can overload the electrical wires in your home. These overloads are often caused by faulty appliances. When an overload occurs, the fuse melts before the wires can overheat, which reduces the risk of fire. Circuit breakers will often trip quicker and more importantly they can be reset to help diagnose and remove faults

1. Always replace a blown fuse with the correct fuse wire. Never use fuse wire that is heavier than the recommended gauge.
2. Never use any other type metal or wire.
3. If fuses keeps blowing, or a circuit breaker keeps tripping, check that your appliances are not faulty.
4. If fuses continue to blow, or circuit breakers continue to trip after appliances are unplugged, there could be a problem with your wiring. Contact a licensed electrician immediately.

Safety switches

Safety switches look similar to circuit breakers, but they provide extra protection from electric shock. Safety switches monitor the flow of electricity and if any irregularity is detected, the electricity supply is immediately cut off.
Homes with children or backyard workshops should consider installing safety switches to reduce the risk of electrical accidents. New homes are required to have safety switches installed. Licensed electrical contractors can install safety switches in older homes at a reasonable cost. You can also purchase portable safety switches for appliances and extension cords. Useful particularly when using power tools outside ie Electric Lawnmowers, Hedge trimmers, Drills, circular Saws etc

PULL THE PLUG… NOT THE LEAD!

Pulling the plug out of the socket by the lead will eventually expose the single wires which weakens its insulation and therefore increases electrocution risk. The Image below shows what happens to plugs pulled out by the leads

KEEP POWER LEADS AWAY FROM HEAT AND WATER.

Heat or water can damage the insulation and create a shock hazard.

POWER LEADS UNDER CARPETS ARE A FIRE HAZARD.

Don’t run electric cords under rugs, through doorways or anywhere they will get excessive wear.

INSPECT POWER LEADS AND POWER BOARDS

Worn, they can cause fires, short circuits or shocks. Check electrical cords and plugs and discard them if they are worn or damaged.

ELIMINATE MULTIPLE CONNECTIONS ON ONE POWER POINT

Plugging a number of cords into one outlet is a fire hazard. It usually indicates that your home wiring is outdated for your needs and that you should have more outlets wired in.

DO NOT CASCADE FROM ONE POWER BOARD TO ANOTHER OR OVERLOAD POWER BOARDS

Generally use Power Boards for Low current devices not Heaters, Kettles, and rotating machinery. Avoid cascading or connecting power boards together in chain arrangement as this may overload a 10 amp power wall socket and cause a fire or compromise the the electrical safety of the items attached to the power boards. Here below is an image of a burnt out power board which ran a 2400 Watt heater plus other electrical items. Note the burnt out socket.

DON’T USE EXTENSION CORDS AS PERMANENT WIRING.

An extension cord is a handy device to temporarily bring power to an area in your home that does not have an outlet. It was never designed to take the place of permanent wiring. Using extension cords as permanent wiring is an indication that your home wiring is not adequate and should be updated.

Many of our clients organise regular test and tagging services simply because it is easier and safer.

A regular program of testing and tagging comprises of: (standard 10/15Amp 3 wire cabled appliance)

A visual check to ensure the integrity of the Electrical cord and Appliance construction

• The Technician looks for Cuts and breaks in appliance and power cables may present as an  electrical hazard.
• An inspection of the integrity of the appliance housing looking for cracks and holes which may expose personnel to an electrical hazard.

A series of electrical tests are then conducted to detect the unobservable faults not found by the visual inspection process, and forms an integral part of the inspection/testing process.

The equipment is turned off to allow the technician access to the appliance plug. All tests are performed by disconnecting the appliance from the building power and connecting the plug to an insulation tester or a Portable Appliance Test-set built for the purpose of performing the tests automatically and uniformly. These Tests are:

1. Earthing continuity test: (specifically for metal shrouded appliances) to ensure there is adequate connection between the earth pin on the plug of the appliance and the metal cover shrouding the appliance.
2. Insulation resistance test: to ensure that no path exists with the appliance/lead for electrical current to transit from the active wires to earth.
3. Continuity Loop test: to make the sure that the active circuit which powers the appliance has a good solid connection and in no way presents as an electrical hazard.
4. Polarity Test: (only for items which distribute power: leads, power-boards, adapters etc) to ensure that the wires of an extension cord/power board appear the same order of connection at the plug as the do at the socket

Other Equipment Tests Include:

 RCD test to test the tripping time of a RCD to ensure your safety switch or RCD does work properly and switches off in a fault situation quick enough to save personnel from Harm.

3Phase Test: usually high powered workshop and building site equipment with multiple active wire connections (tests performed on 3phase test are similar to that of standard appliance tests outlined above)

Emergency Exit sign test: Tests the ability for an emergency exit sign to stay on when power is off 30 minutes is the expected time, if it fails to reach the expected time then the circuitry/ battery will be in need repair or replacement .

That is it, in a very basic overview if you need to know more please either contact us or contact Safe-Work SA (South Australia) http://www.safework.sa.gov.au/  1300 365 255 or The Workplace Safety Authority in your local area.

Electrical Safety Switch Tripping possibilities

Electrical Safety Switches  are RCDs ( Residual Current Devices)  that remove the supply to an electrical circuit when the circuit under protection has detected a leakage to earth. The RCD/Safety Switch responds in mere mili -seconds; avoiding an unsafe condition and thereby potentially preventing electrocution or Fire hazard.

Possible Causes Of Safety Switch/RCD Tripping

Faulty appliance – unplug all electrical appliances, does the RCD reset OK? If the RCD resets OK plug the appliances back in one at a time. Reset the RCD as you plug each appliance back in to find the faulty appliance.

Items with motors or pumps starting – many items with motors or pumps, for instance showers and pond pumps, cause momentary electrical spikes that are big enough to trip RCDs. Seek advice from a qualified electrician.

Older washing machines – aging washing machine heating elements can cause momentary electrical spikes that are big enough to trip RCDs.

Certain wash cycle phases – some cycles of the washing machine, for instance the spin cycle, can cause momentary electrical spikes that are big enough to trip RCDs.

Certain dishwasher cycles – some parts of the dishwasher cycle draw a lot of current, a faulty component, for instance the motor, can trip an RCD.

Overloading a washing machine – too many items in a washing machine can cause certain wash cycles, for instance the spin cycle, to trip an RCD.

Fridges and freezers cooling – the fridge or freezer cooling motor starting.

Turning an heating element on after a long time of being off – moisture in heating elements can trip an RCD, for instance in a sun bed or electric fire. Try resetting the RCD a few times so that the heating element can cause the moisture to evaporate.

Moisture in outside electrical distribution boxes – remove the supply and dry the distribution box. Check the weather seals have not perished.

Moisture in outside electrical sockets – remove the supply and dry the electrical socket. Check the weather seals have not perished.

De-frost timer on a fridge or freezer – a faulty defrost element on a fridge or freezer can cause ‘nuisance’ RCD tripping.

Water heating elements – faulty water heating elements can cause nuisance RCD trips when thethermostat tells them to heat the water.

Moisture in wiring – moisture in the electrical wiring is a common cause of RCD trips. Have you just emptied a bath? Taken a shower? Is it raining – rain can get into the electrical wiring under the floors or in the loft.

As you may have found this list contains certain  conditions that may give clue to an RCD tripping. In most cases this concerns appliances or situations that involve at least one or a combination of  three conditions 1) Moisture leaking electricity to earth in the appliance or premises wiring. 2) A heating element that is either faulty or drawing sudden electrical surges. 3) An appliance with an electric motor that is either faulty or drawing sudden electrical surges.

If you have trouble sourcing constant or intermittent RCD/Safety Switch Tripping then Contact us and we can send a Qualified Electrician around to check it they can source and fix it on the spot.

We have such a large number of gadgets today and they nearly all have sensitive electronic components particularly for our entertainment and computing equipment. We are told that we need to protect that equipment for Electrical surges from our mains power supply. The easiest and most convenient way is to buy a Surge Protected Power Board … However, not all surge protectors are alike, and some even put your gadgets at risk. So what is the Difference between a Surge Protected Power Board and a plain power board? Firstly, not every power board is a surge protected power board. It may sound basic, but it’s a fundamental piece of knowledge you’ll need. While a power board just splits your outlet into multiple ports, a surge protector is designed to protect your computer, TV, and other electronics against power surges and any interference or noise on your power line. Power surges may not be an everyday event, but they’re common enough that they can damage your equipment. What to look for: Look for a Label that states its Surge Protected and also look for a led light on the board which indicates that it the Surge Protection is working when the board is plugged in. This will act as a check if there has been major surge event in the Mains power supply.  If the led light goes off the Surge protection may be blown and it will indicate that it is no longer working even though the board is still supplying power to connected devices. Buy one with right number of outlets they come in typically 6,8,12 outlets (this avoids connecting many boards together compromising your protection and potentially overloading power to appliances from the power-point.) DO NOT buy single a single outlet device they are usually cheap and provide poor protection your expensive appliances. Do not connect High current appliances to a Surge Protected power Board they are designed for sensitive Low Power Devices (Tvs, DVD Players, Game Consoles, Hi-fi, Computer Devices etc) for example, do not connect Kitchen appliances, Air Conditioners, Tools and Workshop equipment to a Surge Protected Power Board Always check the design specifications

• Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200joules. For better protection, look for a rating of 600 joules or more.
• Clamping voltage. The clamping voltage is the voltage that will trigger the surge protector—or essentially when the surge protector wakes up and starts absorbing energy. Look for something around 400 V or less. Lower is better here. Finally, see if response time is listed in the product details—it’s good to know, and lower is better
•  Response time – Surge protectors don’t kick in immediately; there is a very slight delay as they respond to the power surge. A longer response time tells you that your computer (or other equipment) will be exposed to the surge for a greater amount of time. Look for a surge protector that responds in less than 20 nanoseconds.
• As mentioned before,It is best to look for a Surge protected board with an indicator light that tells you if the protection components are functioning

Importantly: Make sure you’re informed before you buy, and read the back of the box or the product details before you buy anything. You don’t want to invest in a surge protector only to find out that it’s far too weak to protect your devices, or it’s a surge protector in name only. Remember,  the most expensive is not always the best. The best thing to do is figure out what you need to protect and buy accordingly.

Electrical Risk Assessment is a necessary step prior to determining a Test & Tag interval of testing

After the work area has been determined as either electrically non-hostile or hostile, a regular inspection schedule can be developed. It is recommended that regular workplace safety inspections are synchronised with the checking periods which are required for electrical equipment.

Non-hostile electrical environment This is a workplace that is dry, clean, With equipment and leads are away from danger from sharps and flexing  or anything else that may result in damage to electrical equipment or the flexible supply cord. In accordance with Safe Work Australia: Code of Practice – Managing Electrical Risks in the Workplace, electrical equipment used in electrically non-hostile operating environments does not require tagging. It is sufficient to visually inspect equipment and cords for damage prior to use and thereafter on a regular basis.

Hostile electrical environment This is a workplace where the equipment or appliance may be subjected to events or operating conditions which could result in damage to the equipment or a reduction in its expected lifespan. What is a Hostile Environment? Is the electrical equipment, when used in normal operation, exposed to any of the following items that might result in damage to the equipment or reduction in its expected life span:

• Mechanical damage?
• Moisture?
• Heat?
• Vibration?
• Corrosive substances?
• Dust?
• Sharps?
• Grease/Oil?

If ‘YES’ to any of the above, the environment is considered ‘hostile’ according to the Australian Standards AS/NZS 3760  for testing & tagging.. Just as a general guide see the table Below… It is taken from the Australian Standards AS/NZS 3760  for testing and Tagging and it forms the basis of State and Industry testing and tagging requirements. Below is a key for identifying the categories in the table and the type of environment in which they are found.

coloured text = Intervals for retesting in a hostile environment.

coloured text = Intervals for retesting in a Non hostile environment.

coloured text  = Intervals for retesting for specific equipment/circumstances without regard to the environment it will be used.

Electrocution incidents can be fatal, since the year 2000 25-30 people die from Electrocution in Australia (http://www.erac.gov.au/ ) 90 percent of these deaths involve non Electrical workers! Many more are seriously injured while non-fatal shocks can result in serious and permanent burn injuries to skin, internal tissues and damage to the heart depending on the length and severity of the shock.

Electric shocks from faulty electrical equipment may also lead to related injuries, including falls from ladders, scaffolding or other elevated work platforms. Other injuries or illnesses may include muscle spasms, palpitations, nausea, vomiting, collapse and unconsciousness. Those working with electricity may not be the only ones at risk. Poor electrical installation and faulty electrical appliances can lead to electric shock to others at or near the workplace.

How can I avoid electrical hazards?

Dependant on the context and conditions, but may include for example:

• Ensure only appropriately licensed or registered electricians carry out electrical work
• Switch off electricity where possible before working on equipment
• Ensure electrical equipment is in good working order (testing and tagging)
• Use battery operated tools rather than mains power tools where possible
• Remove damaged, unsafe electrical equipment or cords from the workplace
• Ensure tag out and isolation procedures are in place and used
• Use residual current devices (or safety switches) with portable equipment (as per the WHS Regulations)
• Don’t overload power sockets. Use power boards not double adaptors
• Meet electrical safety standards

The best way is to meet electrical safety standards is to have your appliances tested and tagged…

In Australia hundreds of fires are caused by potential electrical hazards found in the home apart from fitting a smoke alarm would it not be best that you can reduce these hazards in the first place!

• Replace or repair damaged or loose electrical cords.
• Avoid running extension cords across doorways or under carpets.
• In homes with small children, make sure your home has tamper-resistant (TR) receptacles.
• Consider having additional circuits or outlets added by a qualified electrician so you do not have to use extension cords.
• Follow the manufacturer’s instructions for plugging an appliance into a receptacle outlet.
• Avoid overloading outlets. Plug only one high-wattage appliance into each receptacle outlet at a time.
• If outlets or switches feel warm, frequent problems with blowing fuses or tripping circuits, or flickering or dimming lights, call a qualified electrician.
• Place lamps on level surfaces, away from things that can burn and use bulbs that match the lamp’s recommended wattage.
• Make sure your home has a Safety Switch or Separate RCD breakers for power outlets especially in the kitchen bathroom(s), laundry, basement, and outdoor areas.
