On a vessel, constructed after 1970, carrying grades A, B, C or D cargoes, what can NOT segregate enclosed spaces where sources of vapor ignition are normally present from cargo tanks?

Correct Answer: Option A — galleys

Galleys contain open flames and electrical heating elements representing active ignition sources. Under 46 CFR regulations for tank vessels, galleys can never be used to segregate enclosed spaces containing ignition sources from hazardous cargo tanks.
