OSHA Heat Rules for Concrete Contractors: Pour-Day Records
Which OSHA heat rules apply to concrete crews?
At our September 6, 2026 review, OSHA still described its federal heat standard as proposed. Federal OSHA can address recognized serious heat hazards through the General Duty Clause; state requirements vary. A pour schedule does not establish an exception to worker protection, and a daily heat log does not certify compliance.
This guide offers HeatProof Log's recommended documentation workflow for concrete placement and finishing. It is not an official OSHA form. Its purpose is to make decisions visible: who checked the work area, which resources were available, and what the foreman changed when the original plan no longer fit the job.
Plan the pour as a sequence of work
Before the first truck arrives, describe the placement area, delivery window and crew assignments. Separate pump-hose handling, raking, screeding and finishing in the plan. Record who can arrange relief coverage and contact dispatch if the sequence changes. Avoid leaving the only person authorized to adjust work unreachable during placement.
Identify the actual drinking-water location and recovery area, including how workers reach them without crossing vehicle movements. Record the starting check and the person responsible for replenishment. If the crew includes new or returning workers, confirm that the assigned acclimatization plan has been reviewed before allocating the most demanding work.
Use a change entry when the delivery plan slips
Our recommended log fields are time, slab or work area, active task, observation source, available controls, action and next reviewer. Label weather forecasts, onsite measurements and observations accurately. The temperature of the concrete mix is a production measurement; do not enter it as a measurement of worker heat exposure.
Example: trucks arrive later than scheduled and the finishing crew remains onsite through a hotter part of the day. The foreman records the revised window, verifies the recovery location, arranges relief and assigns the next condition check. Record what actually happened. A planned break should not appear as completed before anyone takes it.
At handoff, explain which section still needs finishing and who owns unresolved water or staffing issues. Keep private medical details outside the shared operations log. A useful entry lets the next supervisor understand the work without reconstructing the shift from text messages, dispatch records and memory.
FAQ: Can finishers wait until the slab is done to recover?
Do not make access to protective measures depend on finishing an entire slab. Plan staffing and sequencing around the site's heat program and applicable rules. Our practical recommendation is to discuss coverage before placement so a worker reporting a problem has a clear person to contact immediately.
FAQ: Does the heat log cover concrete-cutting dust?
No. OSHA identifies cutting and grinding concrete as activities that can generate respirable crystalline silica. Keep the relevant dust-control and respiratory-protection process in place. A heat entry can identify the task and required equipment, but cannot replace exposure controls or the records required by another standard.
FAQ: What should the office review tomorrow?
Review repeated delivery delays, missing replenishment and unresolved relief coverage. Use those observations to improve the next pour plan. HeatProof Log recommends a short supervisor review with named owners; the record should support better preparation instead of becoming a folder of identical checkmarks.
