Reply to comment by paulmarchant in TIL that a typical fire extinguisher only lasts seconds while continuously being sprayed. A 20 pound extinguisher can only be sprayed for 25 seconds. by rtpkickballer
The vast majority of extinguishers you're likely to encounter in daily life are dry chem. CO2 are generally reserved for electrical fires, so if it's extinguished quickly, the equipment will only be damaged rather than destroyed. Occasionally you see them in kitchens, too, but most places will either have foam or a full on fogging system if it's a bigger setup.
