Preventing Electrical Hazards

1
PreventingElectrical Hazards

• Stay away from water
• Dont wear jewelry, rings or watches
• Dont use metal ladders
• Never rub metal objects together when working on
  energized electricity

2
GROUNDING

• Connecting an object to an electrical or earth
  potential

3
GROUNDING
Never remove the ground pin from a plug Ground
all conductive parts of equipment, such
as Pipes Funnels Containers
4
BONDING

• ELECTRICALLY CONNECTING TWO OBJECTS TOGETHER SO
  THEY ARE AT THE SAME ELECTRICAL POTENTIAL OR
  EQUILIBRIUM

5
BONDING

• WHEN FILLING METAL CONTAINERS USE BONDING WIRE
  AND KEEP CONTAINERS CLOSED UNTIL AFTER BONDING.
• ATTACH THE BONDING CABLE TO A SHINY METAL

6
GROUNDING BONDING

• BONDING IS CONNECTED TO GROUND TO PREVENT STATIC
  CHARGES

7
PANEL BOXES
Panel boxes are used to house circuit
breakers that block or isolate energy
8
PANEL BOXES

• Never block panel boxes
• Label all circuits
• Replace circuit breakers with blanks when not in
  use

9
OUTLETS CORDS

• Extension cords should only be used as temporary
  wiring
• Dont overload
• Dont use the gang boxes

10
OUTLETS CORDS

• Always use grounded electrical outlets
• Do not remove grounding post from plug

11
Outlets And Cords

• Do not splice flexible cords
• Electrical Tape is okay
• Do not use cords with exposed wiring

12
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

13
Working on live circuits

• Use only power tools with double insulated
  casings
• De-energize the circuit before connecting test
  equipment.

14
Safety Signs Colors
Emergency cut off switches
Exposed machine parts or electrical shock hazard
Use caution
Location of first-aid or protective equipment
15
Electrical Gloves
Make sure they are ANSI approved electrical gloves
16
Electrical Gloves

• Wear leather gloves over the rubber gloves
• Gloves must be tested every 6 months - even if
  they are new
• Dont wear rings or watches with gloves

17
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
