Use a Class A fire extinguisher on the fire. If you do not have a fire blanket handy, then you can easily use a fire extinguisher on a Class A fire. Ensure that the label on the extinguisher reads Class A.[33]
o To use the extinguisher, aim at the base of the fire and sweep the spray back and forth across it until it’s out.[34]
o If you cannot extinguish the fire within five seconds of using the extinguisher, then it’s too large.[35] Evacuate to a safe place and call 911.
o Solely Class A extinguishers will be silver and will have a pressure gauge for the water inside; however, many multipurpose dry chemical extinguishers will also be rated for Class A fires.[36]
o You can use a carbon dioxide (CO2) extinguisher on Class A fires if it’s the only type of extinguisher you have, but it’s not recommended. Class A objects tend to smolder for a long time, and the fire can very easily reignite as the CO2 dissipates.
