Question 855 Deck Safety

The correct answer is D) A, B or C as marked on the extinguisher. Dry chemical extinguishers can be used on multiple classes of fires, as indicated by the markings on the extinguisher. The classes are: - Class A: Ordinary combustible materials like wood, paper, cloth, etc. - Class B: Flammable liquids and gases - Class C: Energized electrical equipment The extinguisher will be labeled with the specific classes it is rated for, so the user should check the markings to determine which classes of fire it can be safely used on. This makes option D the correct answer, as the extinguisher's use is not limited to just Class B or Class B and C fires.
