Question 850 Deck Safety

The correct answer is B) the multipurpose extinguishing ability. An ABC dry chemical extinguisher has the advantage of being able to extinguish a wider range of fire types, including Class A (ordinary combustibles), Class B (flammable liquids), and Class C (energized electrical equipment) fires. This multipurpose extinguishing capability is a key advantage over a carbon dioxide (CO2) extinguisher, which is primarily effective on Class B and C fires but may not be as effective on Class A fires. The other answer choices are not the main advantages of an ABC dry chemical over a CO2 extinguisher. Lack of toxicity (A) and cooling ability (C) are not the primary distinguishing factors, and while burn-back protection (D) is an important feature, it is not the primary advantage compared to a CO2 extinguisher.
