A portable aerosol fire extinguisher releases chemicals from a spray can in a rapid stream to extinguish a small fire. The fire extinguisher is usually hand-held, typically red in colour and non-rechargeable, allowing for once-only use before discarding.
Serious burns can occur if the aerosol fire extinguisher fails to operate or perform satisfactorily when there is a fire.
The mandatory standard for portable aerosol fire extinguishers came into effect on 22 December 1999 and was last amended 1 January 2005. It covers specific materials and construction, design, charge, performance, testing, labelling and instruction requirements for portable aerosol fire extinguishers.
