Electric Safety training presentation

1. ELECTRICAL SAFETY

2. ELECTRICAL SAFETY
PURPOSE
To provide employees with a safe practices & procedures
to prevent electrical accident or injury.
SCOPE
Electrical Safety work practices are necessary for
employees who work on or near exposed energized parts
or for those who must understand safe practices on the
job.

3. ELECTRICAL SAFETY
Electricity is integrated in our lives at work and at home. BUT NEVER TAKE
IT’S OWER LIGHTLY!
OSHA devotes an entire section of regulations to this area. Focus in on training for:
• Those who work directly with electricity.
• Those who need “basic” instruction.

4. RESPONSABILITIES
Management:
• Understand how electricity acts & how it should
be handled.
• Identify hazards associated with use of
electricity.
• Identify causes of electrical accidents.
• Provide protection to prevent electrical hazards.
• Safety procedure development & maintenance.
• Select and provide appropriate Personal
Protective Equipment.
• Provide employee training.
• Record keeping.
• Review & update of the program

5. RESPONSABILITIES
Responsibilities:
• Understand the hazards
associated with use of
electricity.
• Understand the procedures for
electrical safety.
• Use provided Personal
Protective Equipment as
required.
• Notify immediate supervisor of
any identified hazards when
using electrical equipment or
procedures.

6. HAZARDS OF ELECTRICITY
Hazard means:
Any potential or actual threat to the wellbeing of
people, machinery or environment.
Electrical hazard safety means:
Taking precautions to identify and control electrical
hazards.
The primary hazards of electricity and it’s use are:
• Shock.
• Burns.
• Arc Blast.
• Explosions.
• Fires

7. HAZARDS OF ELECTRICITY - SHOCK
• Received when part of your body
becomes part of the electrical circuit.
• High voltage shock can cause serious
injury or death.
• You will get a shock if you touch:
 Both wires of an energized circuit.
 One wire of an energized circuit and
ground.
 Part of machine that is “hot” because it is
contacting and energized wire and the
ground.
• Can cause tingling, cardiac arrest and
destruction of body parts.

8. HAZARDS OF ELECTRICITY - BURNS
Burns are the most common injury by
electricity. The three types of burns are:
Electrical burns can occur when you come
into direct contact with electricity.
An arc occurs when there is a gap between
conductor and current travels through the air.
Thermal contact burns can occur when
electricity ignites combustible material.

9. HAZARDS OF ELECTRICITY – ARC BLAST
• Occurs when high amperage
currents jump from one conductor
to another through air.
• Happens when opening or closing
of circuits and when static
electricity is discharged.
• Fire can occur if happens in
atmosphere with explosive
mixture.

10. HAZARDS OF ELECTRICITY - EXPLOSIONS
• Occurs when electricity provides
ignitions source for an explosive
mixture in atmosphere.
• Causes range from overheated
conductors or equipment to
normal arcing at switch contacts.

11. HAZARDS OF ELECTRICITY – FIRES
• Electricity is the most common
cause.
• Defective and / or misused
equipment is the major cause.
• Improperly spliced or connected
wiring creates “high resistance”
connections creating heat that starts
fire.

12. HAZARDS OF ELECTRICITY – FALLS
Falling is another common type
of electrical injury. Workers who
experience a shock on elevated
work surfaces such as platforms,
ladders or scaffolds can fall
resulting in serious injury or
death.

13. ELECTRICAL ACCIDENTS
Causes:
Accidents and injuries with electricity are caused by one or a
combination of the following:
• Unsafe equipment and / or installation.
• Unsafe workplace caused by environmental factors.
• Unsafe work practices
Preventing:
Protection from electrical hazards is one way to prevent
accidents, methods of control are:
• Insulation.
• Electrical protective devices.
• Guarding.
• Grounding.
• PPE

14. EFFECT OF CURRENT ON HUMAN BODY

15. ELECTRICAL HAZARDS
To avoid injuries, you should be aware of electrical hazards. Some of the most common electrical hazards are:
• Exposed electrical parts.
Breaker boxes without a cover; Electrical terminals in motors, appliances, an electronic equipment.
• Overload circuits.
Too many devices are plugged into a circuit; the wire insulation melts; an improper overcurrent protection devices is used; no
overcurrent protection device is used.
• Defective insulation.
To protect you, electrical wires are insulated by a plastic or rubber covering. Insulation prevents conductors from coming in contact
with each other and with people.
• Improper grounding.
When an electrical system us properly grounded, there is a path that allows the current to travel to the earth (The ground).
• Damaged power tools.
To protect you from shock, burns and electrocution, tools must: a) Have a three-wire cord with ground and be plugged into a
grounded receptacle. b) Be double insulated. C) Be powered by a low-voltage insolation transformer.
• Overhead power lines.
Overhead power lines are not usually insulated, and cause more than half of all electrocutions.
• Wet conditions.
Wet conditions are hazardous because you can become an easy path for electrical current. There are many circumstances that
create wet conditions: a) Standing in water. b) Wet clothing. c) High humidity. d) Perspiration.

16. HOW TO RESPOND TO ELECTRICAL INCIDENTS
If you come across a person receiving an
electric shock:
• If possible, disconnect the electrical supply
(switch?)
• Assess the situation – never put yourself at
risk
• Take precautions to protect yourself and
anyone else in the vicinity
• Apply the first aid principles
• Assess the injuries and move the casualty to
a safe area if required
• Administer first aid if trained
• Seek urgent medical attention

17. SAFE WORK PRACTICES WITH ELECTRICITY
• Electrical tools should always be in good repair.
• Use good judgment when working near electrical lines.
• Wear provided Personal Protective Equipment.
• Follow Lockout / Tagout procedures when necessary.
• Electrical equipment is to be maintained properly.
• Regularly inspect tools, cords, grounds & accessories.
• Authorized staff ONLY to install and repair equipment.
• Use 3 prong plugs, double insulated tools, safety
switches.
• Machine guards are in place & proper procedures
followed.
• Cables and cords are clean and free of kinks.
• Never carry equipment or tools by its cord.
• Use extension cords ONLY when flexibility is needed.
• DO NOT TOUCH water, damp surfaces, bare wires, etc..
• DO NOT WEAR metal objects when working with
electricity.

18. • The risk of electric shock from correctly installed and maintained power sources is
negligible, provided that sensible precautions are taken by the operator and correct
work procedures are followed.
• Ensure that the right person is carrying out electrical work – licensed versus
competent.
• Electricity is essential but, improperly used, it can be DEADLY!
To STAY ALIVE, you have to STAY ALERT
