Possible applications of dry powders in suppressing supertall buildings fires will be discussed. Development of the agent with the chemical fire extinguishing mechanism is reviewed. Condensed phase compounds including powders of certain alkali metal compounds with gas loaded appear to achieve quicker fire suppression in very tall buildings. Dry powder properties are independent on the flame conditions and so having better suppression performance than other agents. Quantitative information on dry powder suppression behavior, particularly on the effect of size, physical and chemical effects of the powders, and the fire extinction mechanism are still limited. Although the objective of this review article is specifically targeted for fire suppression in very tall buildings, the findings are applicable to fire suppression by dry powders in general.
