Safety Switch: Your Best Investment in Electrical safety

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.

Buyers Guide to Surge Protected Power Boards

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.

WINTER ELECTRICAL SAFETY

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.

Why use an Electrician?

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.

ELECTRICAL FIRE SAFETY


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

Ladder Safety 101

Ladder Safety 

In Australia hundreds of workers and house holders suffer injury and even fatality from a falling off a ladder. This can be from using a ladder to access another area at height or from using a ladder to perform maintenance and installation tasks.

The Basics

Assess the environment before climbing any ladder. Here is a check list

  • Ensure that there is a level and secure footing.
  • It is essential that you secure ladders and lock the safety arms.
  • Check there are no overhead obstacles
  • Also check the area is free from debris around the ladder.

Lock the Ladder

Ladders should always be opened fully and the locking arms locked into place before climbing the steps.  This is true for both step ladders and extension ladders.

Level and Solid Ground for the Ladder Base

Place a ladder on level working surfaces or level the area before attempting to climb the ladder.  This ground should be solid ground.   Use blocking material to level the ladder base.  Choose flat, solid boards or timber that will provide a stable platform

Be aware of your climbing and working limits

Never climb on the top or the next to last step of the ladder.   Never put yourself in a position where you have to stretch in order to reach what you are working on.  Get a taller ladder to complete the task and don’t risk it.

Working with power tools

Power Tools can add to the dangers of standing on top of a ladder.  If a drill bit sticks and jars you around, you may fall right off of the ladder , best if you can tie off a ladder or work with a buddy who is holding the ladder. Do not use power boards on ladders, instead use a heavy duty “Y” split extension cable (one plug supplying 2 sockets) . Where ever possible use connection clips to secure inter- connecting plugs and sockets ensuring they don’t come apart. Also use an RCD power lead when no fixed RCD protection is on offer . When working on Electrical equipment or using power tools it is best to uses a fibre glass ladder it is the best choice for safety from electrical conductivity.

Assess hidden dangers before climbing a ladder

Beware hidden dangers like bare wires and obstacles that you may bump you head on while climbing the ladder.    Ladders also become unstable when your full weight is atop the ladder causing the top to shift and in turn causing your feet to push the top of the ladder in one direction. .

Work with a buddy

Have a helper hold the ladder for support if at all possible.  Having someone foot the ladder and hold the ladder from sliding is always a plus in safety when someone is going up for the first time.  That way the ladder is secure for you to use  and wherever possible and tie the ladder off too.

Climbing  and  Standing On a Ladder Precautions

These tips should be followed to ensure safe operation of ladder work.

Always face the ladder when climbing or descending.

Keep both feet on the ladder, never put one foot on a rung & the other foot on a different surface.

Do not climb higher than 2nd to last rung on stepladders or 3rd to last rung on extension ladders.

Never stand on the top or the paint shelf of a stepladder.

Use Proper Ladder Angles

Don’t place an extension ladder’s angle too steep or spanned too far away from the work area. Follow the manufacturers recommended angle guides for ladder safety. Use the 1:4 ratio to ensure a stable working platform. Place the base of the ladder 1 foot away of whatever it leans against for every 4 feet of height to the point where the ladder contacts at the top.

Electrical Safety makes sense at Home

IF YOU EVER:

Feel a tingle from an appliance or Damage an appliance or Spill liquid on/or near an appliance

Turn off the main switch immediately, then unplug the appliance. Repairs should always be carried out by a licensed electrical contractor. You should also turn off the main switch and contact a professional if you feel a tingle from plumbing, other metal or your sink. This could indicate problems with earthing.

Don’t do it yourself

Attempting to do electrical work yourself is against the law and could cause serious injury or death. All electrical wiring work, including the connection and technical maintenance of fixed appliances, like hotplates, ovens, ceiling fans or water heaters, must be carried out by a licensed electrical contractor. You should always follow the manufacturer’s electrical directions for using and maintaining your appliances. Home made extension cords can be a real hazard too; pre-assembled ones are cheaper and much safer.

Non-electrical DIY work.

Whenever you plan to work around the house or garden, think about the location of powerlines and cables. This is particularly important if you are cutting, nailing or screwing into walls or partitions, or using a metal ladder outdoors.

Home safety checklist

In every room:

  • check for any damaged or broken appliances, power points, light switches or power leads
  • check for any ‘stacked’ double adapters or excessive use of extension leads
  • check for exposed power points within reach of children, and fit plastic safety inserts

In the kitchen

Make sure that small appliances are well away from the sink or draining board

In the bathroom

Remove portable heaters; if necessary arrange to have a proper bathroom heater installed

Make sure everyone in the house knows that hair dryers, shavers, and other appliances must be used only with dry hands and special care is taken ensure that appliances do not come into contact with water.

The laundry, pool or spa

electricity supplies in wet areas should be protected by installed or portable safety switches; these sensitive devices instantly cut off power in the event of an irregularity

use only low voltage (12-24 volt) accessories with, or near pools, fountains, spas or other water installations.

Understanding Electrical Hazards

The 2  Major hazards attributed to electrical equipment and wiring are electrical shock and fire. Electrical shock occurs when the body becomes part of the electric circuit, either when a part of your body comes in contact with both of the active component (Active/Neutral)wires of an electrical circuit, or one wire of an energized circuit and the Earth wire (or grounded wire)…., or a foreign conductive object that has become energized by contact with an electrical conductor.

The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry (ie sweat). Water is a great conductor of electricity, allowing current to
240V can kill!flow more easily in wet conditions and through wet skin. The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. The chart below shows the general relationship between the degree of injury and amount of current for a 60-cycle hand-to-foot path of one second’s duration of shock. While reading this chart, keep in mind that most electrical circuits can provide, under normal conditions, up to 20,000 milliamperes of current flow

Current
Reaction
1 Milliampere Perception level
5 Milliamperes Slight shock felt; not painful but disturbing
6-30 Milliamperes Painful shock; “let-go” range
50-150 Milliamperes Extreme pain, respiratory arrest
1000-4,300 Milliamperes Ventricular fibrillation
10,000+ Milliamperes Cardiac arrest,severe burns & even death

In addition to the electrical shock hazards, sparks from electrical equipment can serve as an ignition source for flammable or explosive vapors.

Even loss of electrical power can result in extremely hazardous situations. Flammable or toxic vapors may be released as a chemical warms when a refrigerator or freezer fails. Fume hoods may cease to operate, allowing vapors to be released into the work area.  So take care with your electrical equipment and consider all contingencies in the operation of that equipment.

About Fuses, Circuit Breakers and Safety Switches

Fuses and 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

Portable Power Tool Safety 101

Introduction.

Using tools in the Workplace requires a lot of forethought and planning. It is important to get to know your tools, its capabilities, its features and most importantly its safety requirements. Neglect to do this and you could risk injury to yourself and others. Being aware of the Job required, the potential hazards around you and knowing how to use the power tool safely will help you minimize these risks.

Read the Manual.

It is of prime importance when using a power tool for the first time is to become familiar with it. Every Time you buy a new power tool, you should read the instructions. Understanding how to properly use the tool can cut down on work related injury.

You see, knowing how to operate the tool will help you understand the tool’s speed, cut depth, and power. Knowing the location of safety features ie emergency shutoff switch and other cut off features which allow the tool to operate safely and effectively.

Risk Assessment.

Perform a risk assessment before beginning any task. Take in all the aspects of the environment your working in, the equipment you are using and any potential hazards that may impact your ability to perform the task safely and effectively. This Risk Assessment should include:

  • Inspecting the leads for cuts, plugs damaged or pulled to expose wires.
  • Get your tools tested and tagged regularly to ensure Safe Operation.
  • Identifying safety guards and shut-off issues.
  • Inspecting blades for looseness or dullness.
  • Identifying cracks or defects in the tool.
  • Ensuring the tool is plugged into a RCD protected outlet or device.
  • Inspecting the area that you will be working on. Wood and other materials where users are drilling or sawing should be clear of nails, steel, electrical lines, and plumbing lines.
  • Always make sure the work area is clear of tripping hazards, fire hazards, and slippery substances.

Wear the appropriate Protective Clothing.

Last but not least ensure that you are dressed for the job. Clothing should not be too loose that it can catch in the power tool, and jewellery should never be worn during operation. In addition, protective clothing suggested for the power tool use should be worn. Protective equipment like eye goggles, hearing protection, and face masks may be suggested by the manufacturer.
