Six Workers, No Perimeter, and a One O'Clock Pour

Exposures:

• Unprotected deck perimeter, 12 ft above the level below. 29 CFR 1926.501(b)(1) requires fall protection at 6 ft or more above a lower level - guardrail system, safety net, or personal fall arrest. The cable was removed for the pump and never restored; that is the controlling violation, and it applies to every worker on that deck, not just the sub's crew.
• Ladder misuse. The top step and top cap of a stepladder may not be used as a step. A stepladder is also not a work platform - sustained overhead rebar work from a ladder is the wrong equipment; it needs a scaffold or an aerial lift.
• Straddling the 6-in. form wall 9 ft up with no fall protection - a classic straddle-and-fall fatality pattern.

Authority and obligation:

• The subcontract's indemnity and "means and methods" language allocates cost between you and the sub. It does not allocate OSHA liability. Under OSHA's multi-employer worksite policy, the creating, exposing, correcting, and controlling employer can each be cited.
• As the GC controlling the site, you have a duty to exercise reasonable care to prevent and detect violations. You walked the deck and saw it. Your exposure is not theoretical.
• You have written stop-work authority and you should use it. That is the answer to the question, not a preliminary.

No unprotected work continues. Not for an hour, not for twenty minutes.

The foreman's argument is the structure of nearly every serious fall injury: brief exposure of an experienced crew on a task that is almost done.

Sequence, fastest fix first:

1. Stop the crew and get your own people out of the area too - you are exposed as the controlling employer.
2. Restore the perimeter. The pump is gone; reinstall the cable guardrail or install temporary rail (42-in. top rail, midrail, toe board) around the working area. This is a two-hour task and it solves 90% of the exposure.
3. Get the ladder workers off the top rungs and off the ladder as a work platform. Bring in a rolling tower or a lift, or have them work from the deck with the top mat placed by other means.
4. Treat the form-wall work as a fall exposure - barricade it or require personal fall arrest with anchorage rated for the load (5,000 lb per employee, or an engineered system) and 100% tie-off.
5. Only then discuss the 1:00 p.m. pour. A two-hour delay is cheap. A fatality costs a life, an OSHA investigation, a willful citation, and your license.
6. If the sub refuses, exercise stop-work in writing, remove your own forces from the area, notify the sub's project manager and the owner immediately, and document the time and the refusal. Do not stand there arguing.

Same-day written notice to the subcontractor's project manager and superintendent, copied to the owner's representative and your company safety officer. It should contain:

• Time, location, and observations - level 4 deck, 7:00 a.m., perimeter cable absent, two workers on the top two rungs of an 8-ft stepladder, one worker straddling a 6-in. form wall 9 ft above level 3.
• Names and crew size where you have them, and the name of the foreman you spoke with.
• The directive issued and the stop-work, with the time it was issued.
• A requirement for a written corrective action plan and a reinspection sign-off by the GC before the pour proceeds. Do not let the pour start on the foreman's word.
• Cost reservation - if your forces install the guardrail or the pour is delayed, state that the cost is for the sub's account and will be handled per the subcontract.
• Follow-up items: verify the sub has a designated competent person on site, request its fall protection plan and toolbox talk record, and get its written acknowledgment of the stop-work.
• Photographs of the condition, taken before anything is corrected, attached to the notice.

One more: if your own forces removed the cable for the pump and never replaced it, that goes in your internal report too. It changes your liability posture and your safety director needs to know before OSHA does.
