This is a Halon single use fire extinguisher once sold by NAPA. It weighs 15.2 oz gross, well above the 13 3/4 oz. disposal threshold, so it's good to go!
Halon has been removed from the market for environmental reasons but it's use is grandfathered. It is the superior extinguisher because it is highly effective on B Oil and C Electrical fires and best of all it leaves no residue. The small Euro fire extinguishers Mercedes once sold for use in their vehicles was a Halon extinguisher. If you don't want a dry chemical to clean up after and you don't want to carry a larger CO2, this little Halon can save your car if a fire starts an burns oil and electric sources. Cheap insurance!
