ARE THE CONTENTS OF A DRY CHECMICAL EXTINGUISHER TOXIC?
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 the Fire Department (9-l-l) to ensure that the fire is completely extinguished.
