Storage for central supply systems should include which requirements?

• A. Have a minimum of two entry/exits if outdoors
• B. All of the above
• C. Secure all cylinders
• D. Have a minimum 1-hour fire resistance rating

Answer: (B)

Storage for central supply systems must protect people, equipment, and the gas contents from hazards. Cylinders should be secured to prevent tipping, rolling, or tampering, using racks, chains, or straps as needed. If the storage area is outdoors, it should provide at least two independent entry/exit routes to ensure safe egress for personnel and access for emergency responders. The space should have a minimum fire-resistance rating of one hour to resist heat transfer and limit fire spread, helping to protect the cylinders and maintain the gas supply during a fire. Together, these measures address containment, accessibility, and fire protection, making all of the listed requirements appropriate.
