There are four main types of electrical injury: Electrocution (causes death), electric shock, burns, and falls. These injuries can result from direct contact with electrical energy, arcing that jumps to a grounded person, thermal burns, including flash burns from the heat generated by an arc, flame burns to materials that catch fire from heating or ignition by electrical currents, and muscle contractions that can cause a The fall can also cause serious injuries. High-voltage contact burns can burn internal tissue while leaving only very minor injuries on the outside of the skin.
There are some protective measures you can take to ensure electrical safety:
1) Inspect tools, power cords, and electrical connections for damage or wear before each use. Repair or replace the damaged tool immediately.
2) Always secure cords to walls or floors with tape when necessary. Nails and staples can damage the cables and lead to fire and electric shock risks.
3) Use cables or devices that are designed for the current or wattage you are using.
4) Always use the correct fuse size. Replacing a fuse with a larger one can cause excessive currents in the wiring and possibly cause a fire.
5) Be aware that unusually warm or hot sockets can indicate unsafe wiring. Unplug all cords from these outlets and do not use them until a qualified electrician has inspected the wiring.
6) Always use ladders made of wood or other non-conductive materials when working with or near electricity or power lines.
7) Do not place halogen lamps near flammable materials such as clothes or curtains. Halogen lamps can become very hot and pose a fire hazard.
8) The risk of electric shock is greater in wet or damp areas. Install ground fault circuit interrupters (GFCI) to break the circuit before a current flow occurs which can cause death or serious injury.
9) Ensure that exposed outlet boxes are made of non-conductive material.
10) Know where the circuit breakers and boxes are located in case of an emergency.
11) Clearly label all breakers and fuse boxes. Each breaker should be clearly labeled as to which outlet or appliance it is intended for.
12) Do not use electrical outlets or cords with exposed wires, and do not use power tools with guards removed. Do not block access to circuit breakers or fuse boxes and do not touch people or electrical appliances in the event of an electrical accident. Always transfer off the strength first.
A ground fault circuit interrupter (GFCI) works by detecting any power failure in a circuit. When a power failure is detected, the GFCI will shut off the power before serious injury or electrocution can occur. In the time it takes for the RCD to switch off the power, a painful shock can occur. It is therefore important to use the RCD as an additional protective measure and not as a substitute for safe working practices.
GFCI wall outlets can be installed in place of standard outlets to protect just that outlet or a series of outlets on the same branch from electrical shock. A GFCI circuit breaker can be installed in some electrical panels to protect an entire circuit. Plug-in GFCIs can be installed in outlets where appliances are used and are commonly found in bathrooms.
Another common application for GFCIs is pools and hot tubs.
Test the GFCI monthly.
First, plug a "night light" or lamp into the GFCI-protected outlet (the light should be on) and then press the "TEST" button on the GFCI. If the GFCI is running properly, the mild must cross out. If not, have the GFCI fixed or replaced. Reset the GFCI to restore power. If the "RESET" button pops out while the light does not go out, the ground fault circuit interrupter has been wired incorrectly and does not provide protection from electric shock at this outlet. Contact a certified electrician to accurate any wiring errors.
Incorrectly used power tools can present an electrical hazard. Switch the tools OFF before connecting them to the power supply. Disconnect the strength delivery earlier than making any adjustments. Ensure that the tools are properly earthed or double insulated. The grounded tool must have an approved 3-wire cord with a 3-pin plug. This plug should be plugged into a properly grounded 3-pin outlet. Do not use power tools in wet or damp environments unless the tool is connected to a ground fault circuit interrupter.
Power tools can ignite flammable substances and cause an explosion in the presence of certain vapors and gases. Never use extension cords as everlasting wiring. Use extension cords only to provide temporary power to an area where there is no electrical outlet. Keep electricity cords far from heat, water, and oil. They can damage the insulation and cause an electric shock. Do not allow vehicles to drive over unprotected power cables. The cables should be laid in a cable duct or protected by boards. Check power cables and plugs daily; dispose of them if they are worn or damaged. Keep the power cables away from the tools during use.
Extension leads themselves can be dangerous. Hang power cords over aisles or work areas to avoid tripping hazards. Do not tie power cords together with tight knots; knots can cause short circuits and electric shocks. Coil the cables or use a plug with a twist lock. Many circuits are wired with twelve-amp circuit breakers. Therefore, do not plug multiple extension cords into one outlet.Here
