Question 851 Deck Safety

The correct answer is B) aimed at the source of the flames. When electrical equipment is involved in a fire, the stream of dry chemicals should be aimed directly at the source of the flames, not used to shield against electrical shock (A), shot off a flat surface onto the flames (C), or fogged above the equipment (D). Dry chemical extinguishers work by interrupting the chemical reaction that sustains the fire, and they must be applied directly to the burning material to be effective. Aiming the stream at the source of the flames is the proper technique to quickly extinguish the fire and prevent it from spreading.
