My Safety Switch has tripped… What should I do NOW !?

A Simple step by step guide to fault finding a tripped Safety Switch.

Note: Some types of appliances may cause incidental or nuisance tripping of your Safety Switch or RCD device. Typically Water Heaters, Electric Jugs and Kettles, Steam Irons, Dishwashers, washing Machines, Swimming Pool Equipment, Auto Defrost Refrigerators and Freezers.
Most Important: If your Safety Switch has turned off, it has done so for a reason. It has detected a leak of some electricity. This may be through a faulty appliance or it may be a fault in the house wiring. These instructions will help you find that leak.

1. First try to turn the Safety Switch on.[Marked Residual Current Device]
2. If it stays on then the fault was intermittent or transient and we can do nothing at this stage. Refer to Note above.
3. Think of what you were using at the time.
If the Residual Current Device trips off again, got to point 5.
4. Turn on the Residual Current Device.
5. If it won’t stay on then you will have to unplug all appliances!
This includes any outside power points or power to outbuildings.
6. At this point the Residual Current Device should stay on. [If not you will need to call an Electrician.]
7. If the Residual Current Device stays on then turn the Circuit Breakers on one at a time.
8. When you come to the leaking circuit, the Residual Current Device will turn off.
9. Unplug all appliances that are plugged in to power points that do not work.
Turn the Residual Current Device on. If it won’t stay on then you will have to call an Electrician.
10. If it stays on, then one of the appliances you have unplugged is faulty. Plug the items in, one at a time until you find the faulty one.

Remember Do not fix any Electrical device yourself, give the device to a suitably qualified electrical repair workshop or if under warranty consult with the manufacturer for the possibility of repair under those warranty conditions.

Understanding the Danger of Electrical shock

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 flow more easily in wet conditions and through wet skin.

240V can kill!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 50-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. So only a very small percentage of current leaking to earth can cause harm if touched by your body… as little as 30 milliamperes of current can KILL !!!

Current
Reaction
1 Milliampere Perception level
1-5 Milliamperes Slight shock felt; not painful but disturbing
6-29 Milliamperes Painful shock; “let-go” range
30-150 Milliamperes Extreme pain, respiratory arrest
151-4,300 Milliamperes Ventricular fibrillation
4,300+ 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.

What to look for when Buying a Smoke Alarm

 Which Type Of Smoke Detector I should buy?

Photoelectric or Ionisation?

The latest advancement In Smoke Detection Technology is the Photoelectric alarm they are widely regarded as being superior to ionisation alarms in most aspects. Not only do they respond faster than other alarms  and are less likely to cause annoying false alarms. Photoelectric alarms are particularly effective at detecting smouldering fires, which provides the earliest possible warning of a fire developing in an enclosed area.

If a smoke alarm has symbol a radioactive warning symbol, then it ionisation smoke alarm.

How many do I need to buy?

It is generally recommended that you should install smoke alarms in all rooms where people sleep and the hallways leading to sleeping areas.

In most states of Australia residents must have at least one working smoke alarm installed on each level of their home. This includes owner occupied, rental properties, relocatable homes, caravans and campervans or any other residential building where people sleep. Contact your Local Fire Authority

Are there approved smoke alarms?

The Australian Standard symbol on the packaging shows if the alarm is approved and safe.Smoke Alarms must meet the requirements of Australian Standard AS 3786.

Hard-wired or battery operated?

In some circumstances your alarms cannot be hard-wired, then it is recommended that these photoelectric alarms run on 10-year lithium batteries. Inbuilt 10-year lithium batteries last as long as the smoke alarm so you don’t need to worry about replacing them every year – you simply replace the entire smoke alarm unit once every 10 years.

Hard-wired smoke alarm

A hard-wired smoke alarm consists of a 240-volt smoke alarm connected to a home’s electrical system with a battery back-up power supply.

Battery operated smoke alarm

Most smoke alarms come with a battery but not all batteries are the same:

  • 10 year lithium batteries: These batteries are recommended and last as long as the smoke alarm.
  • Lead or alkaline batteries: Need to be replaced yearly.

Where can I buy them?

Available at most major supermarkets and hardware stores buy approved smoke alarms meeting Australian Standard AS 3786.

Strobe light and vibrating pad alarms

Strobe light and vibrating pad smoke alarms are available for people who are deaf or hard of hearing. For more information contact the Deaf Society in your local state of Australia

The Electrical Switchboard your backup defence in electrical safety.

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 and RCD devices

Safety switches or RCD device look similar to circuit breakers and will have a test button to provide a test for the correct earth tripping of the device. The purpose is to 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. It is imperative that commercial premises have them installed and tested regularly.. New homes and Commercial premises 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  and these portable RCD should also be tested on a regular Basis!

Surge Power Board Protection 101

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.

What you need to do to manage Electrical Risk in the Workplace

Managing electrical equipment and installations

A business needs to ensure that:

  • power circuits are protected by appropriately rated fuses or circuit breakers
  • electrical leads are not arranged so that they are easily damaged, run across floors or doorways, or over sharp edges
  • only leads and tools designed for wet or damp conditions are used in those conditions
  • circuits where portable equipment may be connected are protected by RCDs
  • if any current protective device (RCD or circuit breaker) is triggered, the system is not re-energised until the reason has been identified by a competent person
  • equipment identified as unsafe is disconnected or isolated and labelled as unsafe and not reconnected until it is repaired and tested as being safe
  • regular visual inspections and testing of electrical equipment, including RCDs, occurs. The nature and frequency of inspection and testing will vary depending on the electrical risks.

So what is tested and what are we looking for when doing a Test and Tag regime?

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 and plugged multi phase equipment)

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 end.

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 90 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.
