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 HazardsAnything 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 EquipmentTo help avoid serious injury follow these basic rules listed below:Treat all electrical equipment as energizedAlways Lockout/Tag-out and or ground equipment prior to performing workWear PPEUse insulated tools when applicableUse caution when using ladders around electricity
6 Electrical Cords Follow these guidelines when working with cords: Protect all cords from physical damageDon’t pull cords too tightNever cut, broken or frayed cordsKeep all cords running on dry surfacesCheck 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 areasFrayed, worn or damaged insulationEquipment operating in damp or hot areasEquipment running near flammables or explosives
8 Miscellaneous Hazards Cont… Plugs that don’t match their outletsTools that smell hot,smoke or sparkEquipment that causes a shock when plugged in
9 Best Work PracticesRemember to follow these best work practices when dealing with electricity:Always follow lock and tag proceduresInspect cords, tools, and other equipment before each useUse appropriate PPEAlways follow manufacture’s instructions
10 Best Work Practices Cont… Make sure electrical tools are cleanMake sure that plugs are compatible with the outletsDo not operate electrical equipment with wet handsTake extra care when working near flammables
11 Instructor’s GuideDiscuss your company policy regarding drop cord maintenance and repair and ground continuity testingDiscuss any areas where overhead lines may pose a problemReview lock and tag and groundingReview the quiz
12 Quiz Electricity travels through cables or wires. T or F Wires made of plastic which conduct electricity are called conductors. T or FPlastic or rubber wrapped around wires to keep electricity contained are called insulators. T or F
13 Quiz Cont…Flow of electricity through a conductor is called current. T or FThe pressure driving electrical current is called voltage. T or FYou should treat all electrical equipment as de-energized before lock and tag. T or F
14 Quiz Cont…Use care when using ladders near overhead power lines. T or FUsing frayed drop cords is not a problem. T or FAll electrical cords should be grounded. T or FIt is not a problem if plugs do not match their outlets. T or F
