Nfpa 53, Materials, Equipment

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, 2016
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

Improvements make it easier to select materials and components, and offer important lessons learned:

Expanded Table F.3.3.8 now includes heat of combustion and autoignition temperature data, in addition to oxygen index data, that can be used to determine the suitability of a longer list of nonmetallic materials for oxygen service.

Must-read new Fire Experience reports in Annex D share vital examples of fire and explosion incidents, based on recent field experience and incident reviews.
