Question 786 Deck Safety

The correct answer is A) oil drums. Portable foam (stored-pressure type) fire extinguishers are most useful in combating fires involving flammable liquids, such as those that may occur in oil drums. Foam extinguishers work by creating a blanket of foam that smothers the fire and prevents the release of flammable vapors, making them effective for Class B fires (flammable liquids). The other options are not the most suitable applications for a portable foam extinguisher. B) The bridge controls would be better protected by a dry chemical or CO2 extinguisher, C) Combustible metals require a specialized extinguishing agent, and D) Generators are better served by a dry chemical or CO2 extinguisher.
