What is the maximum pressure that attack hose is intended to be used at?

The maximum pressure that attack hose is intended to be used at is 300 psi. Attack hose is designed for the delivery of water or other fire extinguishing agents from a fire apparatus to the fire. The construction and materials used in attack hoses allow them to withstand higher pressures than standard hoses, ensuring they can deliver the necessary flow to combat fires effectively.

While other pressures may be relevant in different contexts or for different types of hoses, 300 psi is generally regarded as the maximum working pressure for attack hose used in firefighting scenarios. This rating ensures that firefighters can operate safely while providing sufficient water flow for effective fire suppression. Understanding the correct maximum pressure is crucial for maintaining safety standards and ensuring that equipment functions properly during firefighting operations.
