Electricity runs our facilities—computers, lighting, fueling stations, tools, and equipment—but routine can breed complacency. Typical exposures include overhead lines, electric hand tools, breaker panels, and equipment electrical systems. Stay deliberate and choose the safe action every time.
Electrical Safety
How Electrical Shock Becomes Severe
Severity depends on current, time of exposure, path through the body, voltage, and moisture. Even small mistakes can have big consequences.
Electrical Safety
Effects of Current on the Body (examples)
- 1 mA: slight tingling
- 5 mA: slight shock felt
- 6–30 mA: painful shock, loss of muscle control
- 50–150 mA: extreme pain, muscle contraction
- >1000 mA: heart rhythm interrupted, muscle/nerve damage; death likely
- These ranges show why even “small” currents can be dangerous.

Preventing Electrical Fires and Shock—Field Basics
- Handle cords correctly: Pull from the plug, not the cable.
- Protect the ground: Never use a 3‑prong plug with a missing ground prong.
- Cover & label: Ensure outlet cover plates are installed; keep breaker panels labeled and the area clear.
- Power strips/cords: Don’t overload or daisy‑chain; extension cords aren’t permanent wiring.
- GFCI: Use where water/moisture is present (shops, wash areas).
- Defects: Remove and report frayed/damaged cords and defective tools immediately.

Who Should Do Electrical Work?
Under no circumstances should unqualified personnel open panels or perform electrical work. Use qualified, licensed electrical contractors with proper authorization and insurance.
Electrical Safety
Respect Power Lines—Overhead & Underground
Assume every line is live. Never attempt to move wires. If your vehicle/equipment contacts a line, do not exit the cab—you’re grounded while inside. Call 911 and await instructions. If you’re on foot when wires fall, do not re‑enter the equipment.
Electrical Safety
Quick Pre‑Task Checklist
- Are GFCIs in place where needed?
- Are cords, plugs, and cover plates intact?
- Is the work area around panels clear and labeled?
- Are only qualified pros assigned to electrical work?
- Are power lines located and avoided?
