In fire protection, what does the term "gpm" signify?

In the context of fire protection, "gpm" signifies gallons per minute. This measurement is critical in determining the flow rate of water delivered by fire suppression systems, such as sprinklers or hose lines. A higher gpm indicates a greater volume of water being applied to extinguish a fire, which can be crucial for effective firefighting strategies.

Understanding gpm is fundamental for fire protection professionals as it directly impacts the design and effectiveness of fire suppression systems. Different fire scenarios may require varying gpm levels to successfully control or extinguish flames, making it vital for the calculation of water supply needs and the assessment of system performance during emergencies.
