Employees of the company need to comply with The Company’s policies and procedures dealing with electrical safety.
While this program covers general points to be aware of concerning electrical safety for unqualified personnel, you should also be aware of site specific procedures for your work area and location.

6. Introduction
Because we use electricity for so many things, we often take it for granted.
But electricity can be dangerous! And electrical accidents can have serious consequences:
-Starting fires & explosions
-Damaging machinery & equipment
-Causing injuries, through shock or electrical burns
We should exercise caution when working around and with electricity. To do that properly we need to know how electricity works, and the hazards that it brings with it.

10. Training for Unqualified persons
What is Electricity?
Electrical current is the flow of electrons through a conductor.
Some of the terms we each need to be familiar with are:
Volts (Pressure)
Current (Measured in AMPS)
Resistance (OHM’ s Law)
How current effects the body:
Voltage
Current (AMPS) =
Resistance of Body (Ohms)

11. Training for Unqualified persons
Effect of Electrical Shock is determined by:
Amount of current (AMPS)
Length of time a body part makes contact with electrical current

12. Training for Unqualified persons
Levels of Shock - Any electrical shock must be considered dangerous
Tingling
Skin discoloration
Minor burns
Mild Shock
> 5mA
Numbness/temporary analysis
Pain
Spasms/loss of muscle control
Loss of consciousness
Severe Shock
5mA to 25 mA
Deadly Shock
Greater than 25 mA
Death

13. Training for Unqualified persons
If you saw a person involved in an electrical shock situation, what would you do?
Your safety first: Never use your hands to free a victim frozen by electric shock
Shut power off
Summon help
As a last resort, and if safe to do so, use a dry, non-conductive object such as a wooden chair or broom handle.

14. Electrical Safe Work Practices : (Ground Fault Circuit Interrupts)
Training for Unqualified persons
A GFCI is a device that detects voltage difference as little as 5 milliamps. At 5 milliamps, the power to the electrical tool is disconnected. A GFCI is an important safety device that should be used when operating tools or appliances at work and at home.
(For example, hair dryers come equipped with a GFCI. Also, all new home construction requires outside and bathroom outlets to be GFCI protected.)
