In an O2 project requiring a shutdown of the piped gas system, what is the maximum number of E-cylinders that can be stored in the smoke compartment according to NFPA 99-2012?

According to NFPA 99-2012, the guidelines established for medical gas storage in healthcare facilities are designed for safety and accessibility. When it comes to oxygen (O2) projects, particularly those that necessitate a shutdown of the piped gas system, NFPA 99 specifically addresses the maximum allowable quantity of cylinder storage in smoke compartments.

Among the key points in the regulation, it states that no more than 12 E-cylinders can be stored in a smoke compartment. This limit is put in place to mitigate the risks associated with the potential for gas leaks, fire hazards, and to ensure that healthcare facilities maintain a safe environment for patients and staff. The decision to permit up to 12 cylinders offers a balance between operational needs and safety concerns.

The other options exceed this maximum limit set by NFPA 99-2012, which is why they are not viable. Adhering to these codes is crucial for compliance and the overall safety of healthcare settings, reinforcing the importance of understanding and implementing these regulations in practice.
