Scout's Toolbox Talks

Temporary power setups — including generators, extension cords, and portable panels — are high-risk sources of electrical shock if not installed and used correctly.

Why It Matters:
Construction sites are often exposed to water, movement, and damage — all of which increase the likelihood of electrocution when using temporary power. OSHA Standard 1926.404(b)(1)(ii) requires GFCI protection on all 120V, single-phase, 15- and 20-amp outlets on construction sites.

Key Points:

• Install temporary power according to NEC and OSHA requirements — this includes appropriate overcurrent protection and weatherproof enclosures.
• Use cords rated for outdoor and jobsite use — no household-grade cords.
• Check power panels for labeling and ensure breakers and outlets are identified and protected from tampering.
• Use watertight connections when possible, and elevate cords off the ground to avoid contact with standing water.
• Keep cords and cables clear of vehicle and foot traffic to prevent crushing, cuts, or short circuits.

✅ Safe temporary power prevents fatal shocks and jobsite shutdowns.

Ask the Crew:

• Are all cords and panels rated for outdoor jobsite use?
• Do we have GFCIs on every temporary power outlet?
• Are any wires sitting in water or run through dangerous areas?
