OSHA is preparing several rule updates for 2026 that will impact jobsite safety requirements across the mechanical and construction trades. Two areas especially relevant to HVAC contractors include the proposed national heat‑illness prevention standard and continued emphasis on silica exposure controls.

The heat‑illness standard is expected to require written procedures, access to shade and hydration, acclimatization protocols for new workers, and increased supervisor oversight—important for teams working on rooftops, outdoor condenser installations, and other high‑heat environments.

OSHA is also continuing strict enforcement around crystalline silica, particularly for tasks involving drilling, cutting, concrete pads, and demo work that HVAC crews may encounter on mechanical retrofits.

Contractors are encouraged to begin evaluating their safety programs now, updating training, reviewing PPE and engineering controls, and ensuring consistent practices across all crews and jobsites. Strong compliance can help prevent injuries, reduce workers’ compensation claims, and protect EMR ratings.
