Before you begin
This assessment covers heat illness prevention, recognition, and emergency response on a City of Phoenix contract job site. It tests decisions, not memorisation — several options are plausible and wrong for reasons that matter.
Two modes
- Practice — untimed, coached. Every answer explains itself. Mistakes are recoverable. Start here.
- Assessment — 12 minutes, scored, no coaching until the end. Pass mark is 80%. Critical safety errors end the attempt immediately, exactly as they would end a life.
Scenario briefing
Friday, late July. Phoenix. You are the competent person on a City of Phoenix street-improvement contract — so the city's worker heat safety ordinance applies to you and flows down to your subs. The National Weather Service has issued an extreme heat warning. Forecast high is 112°F. You have a five-person crew and three vehicles.

Competency record
—
This record evidences a scored practical exercise. It is not a competency determination and does not establish qualified-person status — that determination rests with the employer, supported by your written heat illness prevention plan, site-specific instruction, first aid training, and supervision.
