Under what condition can wooden racks for cylinder storage be used?

The correct answer is that wooden racks for cylinder storage are not permitted. This guideline is grounded in safety protocols that prioritize fire prevention and the durability of storage solutions for medical gas cylinders. Wooden materials present a significant fire hazard, particularly in the event of a gas leak or ignition, as they can combust easily and are not capable of withstanding the pressures exerted by gas cylinders.

Regulatory standards typically require that storage systems for gas cylinders be made from non-combustible materials to mitigate these risks and ensure the safety of personnel and facilities. Metals are preferred for their strength, stability, and fire resistance, which make them suitable for securely holding heavy gas cylinders without posing a fire risk or structural integrity concerns.

Additionally, while some options imply modifications (like treating wood for fire resistance or reinforcing with metal), these do not align with standard best practices or regulations, which explicitly discourage the use of wood in such critical applications. Thus, the consensus in safety regulations is to avoid wooden racks altogether for cylinder storage.
