Before starting a purging operation, what is a vital preliminary step?

Inspecting the equipment is essential before starting a purging operation because it ensures that all apparatus is in proper working condition and safe for the procedure. This involves checking for leaks, verifying that all components are functioning correctly, and ensuring that safety features are operational. Adequate inspection helps prevent hazardous situations that could arise from faulty equipment, such as explosions or gas leaks during the purging process.

Filling the vessel with water can pose challenges in purging operations, as purging typically involves removing gas or vapors, while sealing all openings without inspecting the equipment first may inadvertently trap hazardous materials and escalate risks. Turning off alarms is also not advisable; instead, alarms should remain operational to alert personnel of any unexpected issues that may arise during the operation. Therefore, thorough equipment inspection is a foundational safety measure to minimize risks and ensure a safe and successful purging process.
