Electrocution is one of the most common hazards across construction sites according to OSHA(The Occupational Safety and Health Administration). Identifying electrical hazards can help to raise awareness of the risks, their severity, and how they harm people.
Below are usual electrical hazards in the workplace and electrical safety tips on what you can do to mitigate these risks.
Overhead Power Lines
Overhead powered and energized electrical lines can cause major burns and electrocution to workers for high voltages. Ensure to stay away a minimum distance of 10 feet from overhead power lines and nearby equipment. It’s very important to ensure that nothing is stored under overhead power lines when conduct site surveys. Besides, safety barriers and signs must be installed to warn nearby non-electrical workers of the hazards present in the area.
Damaged Tools and Equipment
Exposure to damaged electrical tools and equipment are probably very dangerous. Do remember to call qualified electrician to fix damaged equipment instead of fix anything by yourself unless you are qualified to do it. Double check for cracks, cuts, or abrasions on cables, wires, and cords. Have them repaired or replaced timely if there are any defects. Lock Out Tag Out (LOTO) procedures should be performed at any times before commencing electrical maintenance and repairs. LOTO procedures are for protecting all workers on a worksite.
Inadequate Wiring and Overloaded Circuits
Using wires at inappropriate size for the current can cause overheating and fires to occur. It is important to make sure you are using the correct wire suitable for the operation and the electrical load to work on, and use the correct extension cord designed for heavy-duty use. Also, do not overload an outlet while use proper circuit breakers. Perform regular fire risk assessments to identify areas at risk of bad wiring and circuits.
Exposed Electrical Parts
Exposed electrical parts usually include temporary lighting, open power distribution units, and detached insulation parts on electrical cords. Potential shocks and burns may happen due to these hazards. Secure these items with proper guarding mechanisms and always check for any exposed parts to be repaired immediately.
Improper Grounding
The usual electrical violation is the improper grounding of equipment. Proper grounding can eliminate unwanted voltage and reduce the risk of electrocution. Remember not to remove the metallic ground pin as it is responsible for returning unwanted voltage to the ground.
Damaged Insulation
Defective or inadequate insulation is a potential danger. Be aware of damaged insulation and report it immediately is necessary for safety consideration. Turn off all power sources before replacing damaged insulation and never attempt to cover them with electrical tape.
Wet Conditions
Do not operate electrical equipment in wet locations. Water greatly increases the risk of electrocution especially when the equipment has damaged insulation. To arrange a qualified electrician, inspect electrical equipment that has gotten wet before energizing it.
