Q: What are the requirements for a small storage room becoming a transfer station for filling oxygen cylinders? What code would there be? What type of ventilation do we need if any? Are there any fire ratings required if any?
A: If you’re referring to transfilling liquid oxygen, then you need to comply with NFPA 99-2012, sections 188.8.131.52.1 and 184.108.40.206.2. Specifically, the following is required:
- A designated area separated from any portion of the facility where patients are housed, examined, or treated by a fire barriers of 1-hour
- The area is mechanically ventilated, sprinklered and has ceramic or concrete floor
- The area is posted with signs indicating transfilling is occurring and that smoking in the immediate area is not permitted
- The individual transfilling the containers has been properly trained
- The guidelines of CGA pamphlet P-2.6 are met
If you’re referring to transferring gaseous oxygen from one cylinder to another then you must follow CGA pamphlet P-2.5. Transfilling of any gases from one cylinder to another in patient care rooms of health care facilities is prohibited. See sections 220.127.116.11.2 and 18.104.22.168.3 of NFPA 99-2012.
