Electrical safety

Electricity can cause serious injuries and death if not properly respected and safety protocols followed. There are three main electrical hazards: fires caused by overheating conductors, electrical shocks from contact with a power source, and electrical burns when enough current passes through the body. Many accidents occur due to failure to properly lockout electrical systems during maintenance, use of defective or wet equipment, and not following safe work practices such as grounding equipment and circuits. Proper safety includes never overloading circuits, staying away from unguarded conductors, inspecting cords, and using protective equipment.

Introduction Electricity is an important resource that demands respect. More than 800 people are electrocuted each year. Thousands more suffer disabling injuries from accidental contact with electricity. More than half of these accidents involve the same common low voltage you use in your home. Electricity is the number one cause of fires in the work place.
Electrical Hazards  The most common types of electrical hazards that cause injuries fall into three categories.  Fires  Shocks  Burns
Electrical Hazard - Fire  As the conductor heats, any object with a flash point lower than the heat being generated will cause a fire. Electricity is the #1 cause of fires in industry.
Electrical Hazard - Shock Electric shock occurs upon contact of a (human) body with any source of electricity that causes a sufficient current through the skin, muscles, or hair.
Electrical Hazard - Burns Electrical burns are caused by having enough current pass through body tissue to literally cook the tissue Electrical burns are also caused by arc blasts
Cause of Electrical Hazards  Many electrical shocks occur when safe work practices are not followed. Failure to lockout electrical systems properly for system maintenance and repair  Failure to ground equipment  Use of defective equipment and lines  Use of wet electrical equipment
Rules for Electric Safety  Never overload a circuit  Stay away from all unguarded conductors  To unplug, pull on the plug, not the cord  Use appropriate PPE Safe Work Practices  Use insulating protective equipment  Inspect cords before each use  Don’t use metal objects around electrical equipment
