Development and application status of foam extinguishing agent

The paper presents a review on foam extinguishing agent. The classification, mechanism of foam extinguishing agent, advantages and limitations with applicable scope of different agents are described briefly. The current status of the application of foam extinguishing agent is introduced. Because of its readily biodegradability and environmental benefits, protein foam agent is also an available choice in the alternative options of western countries. In terms of status of aqueous film-forming foams, according to the ＂Convention of Stockholm＂ which severely restricted the use of Perfluorooctane sulfonates （PFOS）, several alternative solutions are offered. For the A Class foam agent, fundamental researches have been conducted on the heat-insulating protection and fire extinguishing performance. New type of stabilizing additive has been invented to enhance extinguishing properties, by the use of alcohol resistant foam extinguishing agent. Compressed N2 foam extinguishing agent and heptafluoropro- pane foam agent have also been hot research topics.
