What is the maximum pressure that supply hoses are intended to be used at?

The maximum pressure that supply hoses are intended to be used at is 200 psi. This standard is based on industry guidelines and testing protocols established to ensure safety and reliability for firefighters during operations. Supply hoses are designed to withstand high pressures, but a maximum working pressure of 200 psi serves as a benchmark to prevent hose failure, which could lead to dangerous situations in emergency scenarios.

Understanding this limit is crucial for driver/operators, as using hoses beyond their rated capacity can not only cause the equipment to fail but also jeopardize the safety of the crew and the integrity of firefighting efforts. Thus, it is essential to adhere to the manufacturer's specifications and industry standards for effective and safe operations.
