Fire streams that deliver less than what volume of gpm are considered handlines?

Handlines are typically defined as fire streams that deliver less than a certain volume of gallons per minute (gpm). The classification can vary between different fire departments or training programs, but it is widely accepted that a handline generally delivers up to 350 gpm.

The reason the correct answer is often considered to be 350 gpm is that this volume allows for manageable handling by firefighters without the need for larger, more complicated apparatus. Handlines are typically used for initial attack efforts, quick suppression tactics, and in situations where mobility and flexibility are necessary. This ensures that firefighters can navigate tighter spaces more easily compared to larger hoses, which are more difficult to maneuver and require larger teams due to the higher water flow requirements.

Thus, understanding the designation of handlines as delivering less than 350 gpm assists firefighters in ensuring they are equipped with the appropriate tools and tactics for the specific fire scenario they are responding to.
