PreventingElectrical Hazards • Stay away from water • Don’t wear jewelry, rings or watches • Don’t use metal ladders • Never rub metal objects together when working on energized electricity
GROUNDING Connecting an object to an electrical or earth potential
GROUNDING Never remove the ground pin from a plug Ground all conductive parts of equipment, such as: Pipes Funnels Containers
BONDING ELECTRICALLY CONNECTING TWO OBJECTS TOGETHER SO THEY ARE AT THE SAME ELECTRICAL POTENTIAL OR EQUILIBRIUM
BONDING WHEN FILLING METAL CONTAINERS USE BONDING WIRE AND KEEP CONTAINERS CLOSED UNTIL AFTER BONDING. ATTACH THE BONDING CABLE TO A SHINY METAL
GROUNDING & BONDING BONDING IS CONNECTED TO GROUND TO PREVENT STATIC CHARGES
PANEL BOXES Panel boxes are used to house circuit breakers that block or isolate energy
PANEL BOXES • Never block panel boxes • Label all circuits • Replace circuit breakers with blanks when not in use
OUTLETS & CORDS • Extension cords should only be used as temporary wiring • Don’t overload • Don’t use the gang boxes
OUTLETS & CORDS • Always use grounded electrical outlets • Do not remove grounding post from plug
Outlets And Cords • Do not splice flexible cords • Electrical Tape is okay • Do not use cords with exposed wiring
Testing And Repairing • Worker should be grounded with wrist straps • Wear clothing that suppresses electrostatic buildup • Use conductive paints or coatings • Insulated floor mats and table mats • Wear conductive footwear
Working on live circuits • Use only power tools with double insulated casings • De-energize the circuit before connecting test equipment.
Safety Signs & Colors Emergency cut off switches Exposed machine parts or electrical shock hazard Use caution Location of first-aid or protective equipment
Electrical Gloves Make sure they are ANSI approved electrical gloves
Electrical Gloves • Wear leather gloves over the rubber gloves • Gloves must be tested every 6 months - even if they are new • Don’t wear rings or watches with gloves
“One Hand Rule” Work with one hand and keep the other at your side or in your pocket. Electricity passing from arm to arm may pass through your heart or lungs; Leaving you paralyzed or dead
