What is the minimum length of a hose that can substitute for a 2A rated fire extinguisher?

The minimum length of a hose that can substitute for a 2A rated fire extinguisher is 100 feet. A 2A fire extinguisher is rated to effectively combat Class A fires, which involve ordinary combustible materials. This rating signifies that the extinguisher can handle a fire with a certain capacity, and a hose of 100 feet offers an adequate reach and volume of water or fire suppression agent to effectively deal with such fires in typical situations. For fire safety, it's important to have the right equipment that meets or exceeds the capacities of traditional fire extinguishers, and a hose of this length helps ensure that firefighters can reach the source of a fire safely and efficiently.
