No. Dry chemical extinguishers are usually filed with Mono-ammonium phosphate. This is a non-toxic substance, however, large amounts of this powder in the air can cause breathing difficulties. Leave the area after discharging a dry chemical fire extinguisher. Call 911 to ensure that the fire is completely extinguished.

The recommended extinguisher for home use is a “Dry Chemical” type, generally type 2A-10BC.
Store your extinguisher away from the stove, near the entrance to the kitchen. Mount the extinguisher on the bracket that is supplied with the extinguisher. In your workshop, mount the extinguisher away from power tools, near the exit.
Caution: Never put yourself or anyone else in jeopardy by trying to extinguish a fire that may be too large. Sound an alarm to other occupants, leave the building close all doors behind you and call the Fire Department (9-1-1). Go to your designated meeting place and wait for firefighters to arrive.
If you are called on to use your extinguisher to fight a fire, just think of the words, PASS:
PULL on the safety pin at the top of the extinguisher.
AIM the nozzle, horn, or hose at the base of the flame (6 to 8 feet away).
SQUEEZE or press the handle.
SWEEP from side to side at the base of the fire until it goes out.
Always follow the manufacturer's instructions as listed on the unit. Never go back into a burning building!
Hardware stores and department stores in your area stock fire extinguishers. You can also refer to the “Yellow Pages” of the phone directory for servicing companies. Most extinguisher servicing companies have units for sale, which are suitable for home use.
