Rooftop Safety
12% of this examRoofing is the deadliest common trade, and the exam tests the numbers and systems that keep crews alive: the 6-foot fall protection rule and its low-slope alternatives, hole covers, ladder and material-handling discipline, power line clearances, hot work, and Florida's ever-present heat.
Core concepts
Fall protection at 6 feet, with low-slope options
Construction work at 6 feet or more above a lower level requires guardrails, nets, or personal fall arrest. On low-slope roofs, a warning line system combined with a safety monitor is an additional permitted method. Painted lines, signs, or verbal warnings never qualify.
Holes and skylights are falls waiting to happen
Covers over roof openings must support twice the load that could cross them, be secured against displacement, and be marked 'HOLE' or 'COVER.' Unguarded skylights count as holes — workers fall through them every year.
Ladders, materials, and power lines
Hoist materials mechanically (ladder hoist, conveyor, boom delivery) so climbers keep three-point contact — never carry bundles up a ladder. Dropping debris more than 20 feet outside the building requires an enclosed chute. Keep 10 feet of clearance from power lines under 50kV; ladders and edge metal conduct.
Heat and fire on the roof
Heat illness controls are water, rest, shade, gradual acclimatization, and watching each other for symptoms — roof surfaces run far hotter than the air. Kettles need a trained attendant and a fire extinguisher; torch work demands flame-resistant clothing, heat-resistant gloves, eye protection, and fire-watch duties after shutdown.
Key facts to know cold
Where it lives in your books
The real exam is open book. Knowing which book — and which tab — answers this domain is worth as much as memorizing it.
Roofing References
Florida roofing is code-first: product approvals, underlayment, and attachment requirements decide questions that would be judgment calls elsewhere. Tab the FBC roofing chapter before anything else.

OSHA 1926
OSHA questions are number questions: heights, depths, distances, and hours. Tab the big subparts and trust the printed number over your memory.

Lookup strategy
- · Tab OSHA Subpart M (fall protection) and 1926.502 — most roofing safety questions resolve to a number printed there.
- · Fall protection thresholds differ by context (6 ft construction, 10 ft scaffolds): read which situation the question describes before answering.
