What is the standard procedure for charging hoses in a fire protection system?

Charging hoses in a fire protection system typically requires a methodical approach to ensure safety and effectiveness. The correct procedure involves charging one side first, which allows for controlled pressure buildup and helps to efficiently clear any air pockets in the hoses.

By charging the left side to 150 psi first, you ensure that all components function correctly and that there is a balance maintained as pressure is introduced into the system. This method helps to avoid sudden surges of pressure that could occur if both sides were charged simultaneously. After charging the left side, proceeding to charge the right side in a similar manner ensures a steady flow of water throughout the hoses and minimizes the risk of pressure-related issues.

This approach also allows firefighters to effectively monitor the integrity of the hose and fittings during the charging process. If any leaks or issues arise, they can be identified and addressed more easily when charging one side at a time, rather than subjecting the whole system to pressure suddenly. Hence, this methodical charging procedure enhances safety and operational effectiveness within fire protection systems.
