When transporting compressed gas cylinders, what must be securely fastened?

• A. Weight distribution brackets
• B. Approved valve protection caps
• C. Safety harnesses
• D. Warning signs

Answer: (B)

When transporting compressed gas cylinders, securing the approved valve protection caps is essential because these caps are designed to protect the cylinder valves from damage during transport. If the valve is compromised, it could lead to gas leaks, which pose serious safety hazards such as explosions or asphyxiation from gas inhalation.

The valve protection caps not only prevent physical damage to the valves but also help ensure that gases remain contained within the cylinders until they are ready to be used. This is particularly important for maintaining both workplace safety and regulatory compliance.

Other measures such as using weight distribution brackets or safety harnesses may aid in stabilizing the load, but they don't specifically address the safety of the valves themselves. Warning signs might be necessary for visibility, but they do not contribute directly to the mechanical protection of the gas cylinder's critical components. Therefore, focusing on securing the valve protection caps is paramount for safe transportation of compressed gas cylinders.
