A crew begins heavy rooftop replacement work during extreme heat. Which prevention and emergency provisions belong in the plan?
- Heat-illness prevention plan
- BLess water to reduce breaks for the described HVAC equipment and measured operating conditions
- CNo buddy checks
- DDark clothing only
Why A is correct
The best answer is: Heat-illness prevention plan. Roof surfaces intensify heat and new workers may not be acclimatized. California heat-illness controls must be active before symptoms appear. The transferred operating condition requires the same design, installation, diagnostic, or safety principle in a different HVAC context. The other choices skip a prerequisite, conflict with the listed procedure, or treat a symptom without controlling its cause.
