The C354TS is the smallest Halon fire extinguisher with a discharge hose (to facilitate proper upright use). Twenty percent more Halon 1211 than model C352TS, is the same size and uses the same mounting bracket. Halon is a "Clean Agent" – a gaseous fire extinguishant that does not leave a residue. Halon is extraordinarily effective in putting out flammable liquid and electrical fires. As a liquefied gas, Halon is able to effectively fight hard-to-reach fires by chemically disrupting combustion.
