1 Hazards Of Electricity General Safety Precautions

2 Basic Principles of Electricity Electricity travels through wires or cables and since they conduct electricity we call them conductors. The wires are wrapped in plastic or rubber to keep the electricity contained and are called insulators. Current refers to the flow of electricity through a conductor.

3 Basic Principles of Electricity Cont… Current is measured in amps and be equated to measuring water in gallons per minute. Voltage measures the pressure driving electricity through the conductor. Electrical shock occurs when a part of your body creates a complete circuit between a conductor and another conductor or grounding source. This may cause death.

4 Electrical Hazards Anything that runs on electricity is a potential hazard. It doesnt have to be a big fancy industrial machine to be dangerous. A small break room appliance can cause an electrical injury.

5 Energized Equipment To help avoid serious injury follow these basic rules listed below: Treat all electrical equipment as energized Always Lockout/Tag-out and or ground equipment prior to performing work Wear PPE Use insulated tools when applicable Use caution when using ladders around electricity

6 Electrical Cords Follow these guidelines when working with cords: Protect all cords from physical damage Dont pull cords too tight Never cut, broken or frayed cords Keep all cords running on dry surfaces Check all cords for ground and continuity

7 Miscellaneous Hazards Always be aware of the following when working around cords and electrical tools: Wires running across traffic areas Frayed, worn or damaged insulation Equipment operating in damp or hot areas Equipment running near flammables or explosives

8 Miscellaneous Hazards Cont… Plugs that dont match their outlets Tools that smell hot,smoke or spark Equipment that causes a shock when plugged in

9 Best Work Practices Remember to follow these best work practices when dealing with electricity: Always follow lock and tag procedures Inspect cords, tools, and other equipment before each use Use appropriate PPE Always follow manufactures instructions

10 Best Work Practices Cont… Make sure electrical tools are clean Make sure that plugs are compatible with the outlets Do not operate electrical equipment with wet hands Take extra care when working near flammables

11 Instructors Guide Discuss your company policy regarding drop cord maintenance and repair and ground continuity testing Discuss any areas where overhead lines may pose a problem Review lock and tag and grounding Review the quiz
