Before you think of handling any electrical equipment, you must know all the basic precautions to be put in place while working with an electrical equipment. Safety must not be compromised and some ground rules need to be followed first.
You must be very cautious and work safely. Safety rules help you control risk of injury or death from workplace hazards.
If you are working on electrical circuits or with electrical tools and equipment, you need to Ensure the Following Basic Precautions
[1] AVOID WATER
Avoid water at all times when working with electricity. Never touch or try repairing any electrical equipment or circuits with wet hands. It increases the conductivity of electric current. Avoid standing on a wet surface while working with electrical equipment. Also, when working with equipment near electrical circuits, don’t work with wet hands. Keep towels nearby so you don’t run the risk of becoming the conduit for an electric current.
[2] USE INSULATED TOOLS
Before you make use of any electrical equipments or tools, make sure it’s insulated with any insulating material either robber, plastics or even wood just to avoid unnecessary shock.
While it may be necessary to make notes or measurements during an electrical job, avoid using anything metallic such as rulers, pens, or pencils. It is also recommended not to wear any metal-based jewelry such as watchbands, chains, or rings. If you have piercings with metal studs, it would be wise to remove these as well as a safety precaution.
[3] INSPECT ALL CORDS BEFORE WORKING ON IT
Damaged or worn cords can cause a short circuit leading to fire or shock. All cords, including lamp cords, electronic cords, extension cords and small appliance cords should be inspected before working on it, at least the wires can become dry and brittle and crack. Make it a habit and do it at the same time you replace the batteries in your smoke alarms.
[4] PUT ON YOUR SAFETY WEARS
When it is necessary to handle equipment that is plugged in, be sure hands are dry and, when possible, wear nonconductive gloves, protective clothes and shoes with insulated soles. Make sure all your wears are non conductor of electricity, avoid the use of chains, stainless wristwatch or an conductive accessories.
Do not wear loose clothing or ties near electrical equipment. Act like an electrical engineer, you are not on the beach.
[5] NEVER WORK ON AN ENERGIZED EQUIPMENT
Never try repairing energized equipment. Always check that it is de-energized first by using a tester. When an electric tester touches a live or hot wire, the bulb inside the tester lights up showing that an electrical current is flowing through the respective wire. Check all the wires, the outer metallic covering of the service panel and any other hanging wires with an electrical tester before proceeding with your work.
[6] DON’T USE A STEEL OR ALUMINUM LADDER FOR ELECTRICAL WORK
Never use an aluminium or steel ladder if you are working on any receptacle at height in your home as shown in the diagram above. An electrical surge will ground you and the whole electric current will pass through your body. Use a bamboo, wooden or a fibreglass ladder instead.
[7] WEAR GOGGLE WHILE USING SOLDERING IRON
Always take care while soldering your circuit boards. Wear goggles and keep yourself away from the fumes. Keep the solder iron in its stand when not in use; it can get extremely hot and can easily cause burns.
