What type of hose is typically used with a Class II standpipe system?

• A. Supply hose
• B. Garden hose
• C. Attack hose
• D. Discharge hose

Answer: (C)

In a Class II standpipe system, the type of hose typically used is attack hose. This type of hose is specifically designed for delivering water directly to the fire from the standpipe system. Attack hoses are constructed to withstand the high pressures associated with firefighting and provide the necessary flow rates needed to effectively combat a fire. Class II standpipe systems are primarily intended for use by trained personnel, such as firefighters, and the attack hose connected to them allows for quick deployment and efficient suppression efforts. The hoses are generally smaller in diameter compared to supply hoses, which are used for drawing water from a source and connecting to a pump. In contrast, discharge hoses are utilized to transport water away from a source, typically in a different application, while garden hoses are not suitable for fire suppression purposes due to their lower pressure ratings and less durable construction.
