How To Guide

Heat kills workers each summer, and most victims are in their first days on a hot job. This guide turns OSHA and NIOSH heat guidance into a working routine: the water-rest-shade cycle, the 7-to-14-day acclimatization ramp, the heat index numbers that change the plan, cooling vests and towels that actually work, and the signs that mean 911.

Attics combine a floor you can fall through, insulation that inflames skin and lungs, live wiring, and summer temperatures of 130F or more. This guide covers joist footing, the N95-goggles-coverall PPE stack for fiberglass, the heat plan that decides when to climb up, and the red flags - vermiculite, mold, droppings - that mean stop.
