Electricity (Internal Links)

By

Electricity can kill. The danger can strike in the form of lightning, contact with power lines or current from equipment that uses electricity.

Electricity travels in circuits. An electric shock occurs when a person becomes part of the electric circuit that the electricity is moving through. The seriousness of the shock a person receives depends on the amount of current (amperes), the path of the current through the body and how long the exposure lasts.


WARNING!!! Low voltage does NOT imply low hazard!

A health and safety program should include work practices to prevent shocks and electrocution. Safety measures include:

  • having only qualified workers install and maintain electrical systems; 

  • using proper electrical outlets instead of overloading extension cords; 

  • not allowing electrical cords to come into contact with water; 

  • using ground fault circuit interrupters (GFCI) where electrical equipment and cords may come into contact with water. The GFCI cuts the circuit before the electricity reaches the worker. 

  • properly grounding electrical equipment; 

  • keeping a safe distance from overhead power lines; 

  • locating underground utility wires before digging; and 

  • finding shelter during rainstorms when there is lightning and thunder.
