Electrical Safety Training

Why This Matters

Electrocution is one of construction's "Fatal Four". There are approximately 160 electrical deaths per year in construction.

How Electricity Kills

Current through the body causes burns, cardiac arrest, and muscle lock. As little as 50 milliamps (mA) can be fatal.

GFCI Protection

Ground Fault Circuit Interrupters (GFCIs) are required on all 120V temporary power on construction sites. Always test before each use.

Overhead Power Lines

Maintain minimum clearance distances and always assume all lines are energized. A spotter is required when working near lines.

Wet Conditions

Water is a conductor of electricity. Never use damaged cords in wet areas. GFCI protection is critical in these conditions.

Extension Cords & Temporary Wiring

Inspect daily for damaged insulation, ensure proper grounding, and never daisy-chain extension cords.

Arc Flash & Lockout

Wear proper PPE for electrical work and always lockout/tagout (LOTO) before working on circuits. Only qualified persons should work on energized circuits.

Key Takeaways

• Electrical safety saves lives.
• Always use GFCI protection.
• Respect overhead power lines and clearance distances.
• Avoid wet conditions with electrical equipment.
• Inspect cords daily and never daisy-chain extension cords.
• Follow lockout/tagout procedures and PPE requirements.
• Qualified persons only for energized electrical work.
