NFPA 53:2016

NFPA 53 combines new requirements and real-world experience to advance safety in Oxygen-Enriched Atmospheres (OEAs).
Developed by experts, NFPA 53: Recommended Practice on Materials, Equipment, and Systems Used in Oxygen-Enriched Atmospheres is your single source for the latest criteria for the safe use of oxygen (liquid/gaseous) and the design of systems for use in oxygen and oxygen-enriched atmospheres. Information is provided for the selection of materials, components, and design criteria that can be used safely in oxygen and OEAs.
Extensively used by designers, engineers, and facility managers in health care, industrial, and fire service fields, NFPA 53 applies to:
Gas and compressed air supplies
Medical applications, including home oxygen systems
Spaceflight operations
Industrial processes
Welding applications
Self-contained breathing apparatus (SCBA)
Self-contained underwater breathing apparatus (SCUBA)
Underwater tunneling and caisson work
Commercial and military aviation
