According to NFPA 1901, a pumper with a capacity of 500 GPM or less should be capable of flowing how many GPM from their booster tank?

NFPA 1901 sets standards for the design and performance of fire department vehicles, including pumpers. According to these standards, pumpers with a capacity of 500 gallons per minute (GPM) or less are required to have the ability to flow a minimum of 250 GPM from their booster tank. This specification ensures that even smaller pumpers can deliver adequate water supply for firefighting operations without relying solely on external water sources.

The requirement for 250 GPM allows for effective initial attack capabilities, especially in situations where immediate water is needed and time is of the essence. This is particularly important in rural or less developed areas where hydrant availability may be limited.

Other choices, such as 100 GPM, 500 GPM, and 750 GPM, exceed or do not meet the established standard for a pumper of this size, highlighting the importance of adhering to NFPA guidelines to ensure all firefighting apparatus are equipped to provide the necessary fire flow capabilities in various emergency situations.
