What defines a gas room?

A gas room is specifically designed for the storage and use of compressed gases, and it must be separately ventilated to ensure safety and compliance with regulations. This definition is crucial because a gas room typically houses medical gases, which require strict controls to prevent hazards such as leaks or explosions. Proper ventilation is essential to maintain air quality and dissipate any potentially dangerous gas accumulations.

The other choices focus on aspects that do not align with the specific requirements and functions of a gas room. Multiple ventilation sources or general storage does not meet the targeted safety standards and regulations necessary for managing compressed gases. Likewise, a space for handling combustible materials is unrelated to the characteristics of a gas room. Thus, understanding the unique purpose and design of gas rooms is vital for ensuring safety in environments that utilize piped non-flammable medical gases.
