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 doesn’t 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
Don’t 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 don’t 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 manufacture’s 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. Instructor’s 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
