Subcontractor Coordination on Multi-Employer Sites

Why it matters

On a multi-employer site, the crane crew, the electricians, and the roofers can each be perfectly safe alone and still hurt each other: a load swung over another trade, power energized under someone’s hands, a floor opening cut where another crew walks. OSHA holds both the creating and exposing employers responsible. Today: how hazards cross crew lines here, and how we talk before they do.

Hazards

• ⚠ Overhead work by one trade above another’s heads
• ⚠ Hazards created by one crew and inherited by the next shift or trade
• ⚠ Energizing, pressurizing, or testing systems other crews are touching
• ⚠ Guardrails, covers, and barricades removed by whoever needed them out of the way
• ⚠ Conflicting traffic: deliveries, lifts, and crews in the same corridor
• ⚠ Nobody sure who controls a shared hazard

Controls and safe practices

• ✓ Attend the site coordination meeting and bring back what affects us: overhead work, closures, energizations.
• ✓ Communicate before creating exposure: warn affected trades before hot work, floor cuts, or energizing anything.
• ✓ Never remove another trade’s protection (rails, covers, locks); get the controlling contractor to resolve it.
• ✓ Protect what we create: our openings, our leads, our stored material are guarded to protect EVERY trade.
• ✓ One controlling authority per shared system: locks and tags coordinated across employers.
• ✓ Report cross-trade hazards to the GC immediately, and to the exposed crew directly if it cannot wait.
• ✓ Walk the overlap zones with the other foreman when schedules stack trades vertically.

Crew discussion questions

1. Which trades are above and below us this week?
2. What hazards are we creating that other crews inherit?
3. Who is the GC contact when we find another trade’s hazard?
4. Is any of our protection (rails, covers) likely to be in someone’s way?
