What must be done with cylinder valve protection caps?

• A. They can be removed when not in use
• B. They must be securely fastened and protected
• C. They are optional if no leaks are detected
• D. They should be labeled with warning signs

Answer: (B)

Cylinder valve protection caps serve a critical safety function in the handling and storage of gas cylinders. Properly securing and protecting these caps ensures that the cylinder valves are shielded from accidental damage, which could lead to leaks or catastrophic failures. An intact protection cap prevents dirt, debris, and moisture from entering the valve, which is crucial for maintaining functionality and safety in operations involving pressurized gases.

Furthermore, if the cylinder were to be knocked over or improperly handled, having the protection cap securely fastened reduces the risk of the valve being inadvertently opened or damaged, which could create hazardous situations, including the potential for explosions or uncontrolled gas escape. This practice is consistent across safety guidelines in the industry, emphasizing the importance of maintaining cylinder integrity at all times, regardless of their immediate use status. The necessity of this safe practice is underscored by regulatory standards and best practices in workplace safety.

Other options, such as removing the caps when not in use or considering them optional, fail to acknowledge the critical role these caps play in safety and risk management. Lacking secure protection could expose the valves to undue risks and compromise safety protocols in handling gas cylinders. This underscores why securely fastening and protecting the cylinder valve caps is not only a safety protocol but often a regulatory requirement.
