When should a leaking cylinder be labeled as "DEFECTIVE"?

Labeling a leaking cylinder as "DEFECTIVE" before gas has escaped is essential for ensuring safety in the work environment. Identifying and marking the cylinder immediately upon detection of a leak prevents accidental use and alerts personnel to the potential hazards associated with the cylinder.

This proactive approach minimizes risks, as it allows for timely action to be taken—such as isolating the cylinder and following proper procedures for handling, repairing, or disposing of defective equipment. Not waiting for gas to escape helps prevent the possibility of hazardous situations, such as fires, explosions, or exposure to harmful gases.

In scenarios where a cylinder is only marked after the gas has escaped or when waiting for a replacement to arrive, there could be elevated risks of accidents or injuries. Thus, timely labeling is crucial for maintaining a safe working environment.
