Question 239Safety & Environmental - QMED

The correct answer is B) at the seat of the fire, starting near the edge. When fighting a Class B fire (flammable liquid or gas fire) with a portable dry chemical extinguisher, the proper technique is to direct the discharge at the base or seat of the fire, starting near the edge and sweeping it across the entire surface. This allows the dry chemical agent to smother and extinguish the fire at its source. The other options are incorrect because: A) bouncing the discharge off a bulkhead is an inefficient technique, C) directing the discharge at the main body of the fire may not reach the seat, and D) discharging over the top of the fire is unlikely to effectively smother the base of the flames.
