Question

Which type of fire stream is supplied by 1½- to 3-in. (38- to 77-mm) hose, and discharges from 40-350 gallons per minute (gpm) (160-1,400 liters per minute [L/min])?

a. Master stream
b. Hand line stream
c. Low-volume stream
d. High-volume stream

Answer 1

A fire stream discharging from 40-350 gpm (160-1,400 L/min) supplied by a 1½- to 3-in. hose is called a hand line stream.

Step-by-step explanation:

The type of fire stream supplied by 1½- to 3-in. (38- to 77-mm) hose that discharges from 40-350 gallons per minute (gpm) (160-1,400 liters per minute [L/min]) is known as a hand line stream.

This type of stream is typical for use by firefighters and involves lines that can be managed and directed by hand as opposed to those that are fixed or require mounting due to their higher volume and pressure requirements.
