In order to comply with code, what is the maximum distance of unsupported hose fittings in fire protection systems?

In fire protection systems, the requirement for unsupported hose fittings is crucial to ensure reliability and safety during operation, particularly under various environmental conditions. The maximum distance of unsupported hose fittings set at 6 feet is established to prevent excessive strain on the fittings and hoses, which may lead to failures or leaks during use.

Hoses that are too far from a stable support risk tension or damage, especially if subjected to water pressure, movement, or environmental factors. Building codes, like those from the National Fire Protection Association (NFPA), set standards to ensure the integrity of fire protection systems, ensuring that all components function effectively when needed. The specification of 6 feet balances practical installation considerations while maintaining safety standards, making it the correct maximum distance for unsupported hose fittings in fire protection systems.
