The hoods over galley ranges present what major hazard?

Correct Answer: Option B — Grease collects in the duct and filter and if it catches fire is difficult to extinguish.

Galley range hoods and exhaust ducts accumulate grease deposits over time. Per 46 CFR standards, these combustible residues present a major fire hazard because intense galley fires can ignite the grease, traveling rapidly through ductwork and defying standard extinguishing efforts.
