Heatwave sparks emergency rule July 09 2021 Oregon OSHA adopts emergency rule to protect workers from the dangers of high and extreme heat. Oregon OSHA announced Thursday that it adopted an emergency rule aimed at protecting workers from the dangers of high and extreme heat. The temporary rule takes effect immediately and remains in place for 180 days, during which time framers will be working on a permanent heat-stress prevention rule anticipated to be adopted in the fall. The temporary rule was adopted following direction from Oregon Gov. Kate Brown to enact emergency measures. It comes in the wake of an extreme, record-breaking heatwave that claimed more than 100 lives in Oregon, including Sebastian Francisco Perez, who died while working on a tree farm in St. Paul during the height of that heatwave.
