The maximum length for the main fire system hose at LNG facilities is specified as 100 feet or less. This limit is established to ensure effective firefighting capabilities while maintaining control and manageability of the hose during emergencies. A shorter hose is easier to maneuver, reduces the potential for kinks or damage, and allows for more effective and efficient deployment in high-stakes situations.

While longer hoses may seem like they could cover more distance, they can hinder response times and make it more challenging to maintain the pressure and flow of water needed to combat a fire effectively. The 100-foot maximum length strikes a balance between reach and operational control, which is critical in the high-risk environment of LNG facilities where rapid and efficient response to fire hazards is essential for safety.
