This document discusses electrical safety on construction sites. It outlines safety requirements, hazard prevention and control, and personal protective equipment. The most frequent causes of electrical accidents are contact with power lines, lack of ground fault protection, improper use of equipment and cords. The most common injuries from electrical accidents are electrocution, shock, burns and falls. Workers must always assume overhead lines are energized and never touch downed power lines or operate equipment in water.

2. ELECTRICAL SAFETY
• Topics:
– Safety requirements
– Hazard prevention & control
– Most common injuries
– Personal protective equipment

3. Basic Electrical Safety
• Always assume that all overhead wires are
energized
• Never touch a down power line
• Never operate electrical equipment while
standing in water
• Coming in contact with electrical voltage can
cause serious injury or death

4. Most Frequent Causes
of Electrical Accidents
• Contact with power lines
• Lack of ground fault protector
• Missing ground on electrical cords
• Improper use of equipment
• Improper use of electrical cords

5. Hazard: Exposed Electrical Parts
• Isolate electrical parts
• Use guards or barriers
• Replace covers

6. Hazard: Conductors Entering Boxes
• Must be protected from abrasion
• All openings must be closed to prevent access

7. Hazard: Overhead Power Lines
• Usually not insulated
• Carry extremely high voltate
• 80%of all lineman deaths were caused by
contacting a live wire with a bare hand
• Cranes, scaffolds, ladders can all contact
power lines

8. Most Common Injuries
• Electrocution or death
• Shock
• Burns
• Falls

9. Personal Protective Equipment (PPE)
• PPE should always be first line of defense
• Rubber gloves, rubber boots, hoods, sleeves,
blankets should be worn

10. Summary
• Electrical equipment must be:
– Listed & labled
– Free from hazards
– Used in proper manner
– If you use electrical tools you must be protected
from electrical shock & use necessary safety
equipment
