Electrical Hazards

Electrical hazards are doubly hazardous in that there is not only the chance of electrocution, but there is also the probability that any electric shock will cause a loss of consciousness that may well result in a fall of some sort. Today we will discuss methods of receiving an electric shock and ways to avoid electrical hazards.

Guide for Discussion

Methods of Receiving an Electric Shock

• From a defective power tool.
• From defective extension cords.
• From overloading a switch or over-riding a by-pass.
• By not grounding electrical equipment or using Ground Fault Circuit Interrupters.
• By coming in close contact with live electric lines.
• By coming too close to high power lines with the power arcing over and making contact.

Ways to Avoid Electric Hazards

• Use Ground Fault Interrupters (GFCI’s) on all jobsites.
• Always inspect tools and equipment for frayed cords and defective plugs before using them.
• Never use a power tool that has had the ground plug removed; inspect the plug.
• Never stand in water and operate a power tool without proper (i.e., insulated) footwear.
• Keep extension cords out of water when in use.
• Consider all power lines “live” and avoid contact with them.
• Follow the company assured grounding/electrical protection program.
• Disconnect all electrical tools and cords when not in use.
• Be use all temporary lighting is equipped with bulb covers.
• Make sure all power supplies, circuit boxes and breaker boxes are properly marked to indicate their purpose.

Additional Discussion Notes:

Who is responsible for the company assured grounding program or to install a ground fault interrupter system?

Remember: The best way to eliminate the hazard of the “quiet killer” is to act as if each exposure to an electrical hazard may be your last. Never take electricity for granted, “it’s a killer.”
