What safety measure should be taken with safety valves attached to steam drums?

Ensuring that safety valves are accessible for maintenance and testing is a crucial safety measure in any system involving steam drums. These valves are designed to release pressure to prevent potential hazards such as explosions or equipment failure. Maintaining accessibility allows for regular inspections and service, ensuring that they function correctly when needed. Operators can easily check for wear, perform necessary adjustments, and conduct tests to verify that the valves will activate as intended in case of an overpressure situation. This proactive maintenance is vital for the overall safety and efficiency of the steam system, as it minimizes the risk of failure during operation.
