WHA engineers have oxygen fire expertise unparalleled in industry, spanning nearly all industries that use oxygen and other non-oxygen oxidizers. We know oxygen fires like no one else.
WHA engineers take the mystery out of oxygen fires using their unparalleled oxygen fire expertise, spanning nearly all industries that use oxygen and other non-oxygen oxidizers. Beginning in the 1980s, WHA engineers have provided oxygen compatibility guidance, training, and failure analysis for the aerospace, welding, commercial gas, petrochemical, medical oxygen, and medical device industries. WHA has investigated hundreds of fires and incidents in most industries that use oxygen and have developed tools to harden systems against oxygen-related fire hazards.
- WHA has extensive oxygen safety and failure analysis expertise and provides services worldwide. WHA’s oxygen technologies uniquely sets WHA apart from virtually all other commercial firms in our industry.
- WHA brings NASA’s oxygen expertise to commercial industry. WHA engineers were among the NASA engineers that designed, fabricated, and implemented many of the oxygen and hazardous fluids test systems used by the space program during the Apollo, Space Shuttle, and International Space Station programs. WHA engineers participated in the qualification of many flight hardware systems and materials compatibility screening tests performed in support of the first 117 NASA Space Shuttle flights.
- WHA’s oxygen experience spans nearly every industry that uses oxygen. Beginning in the late 1980s, WHA engineers provided oxygen compatibility guidance, training and failure analysis for the aerospace, welding, commercial gas, petrochemical, medical oxygen and medical device industries. WHA has investigated fires and incidents in most industries that use oxygen and has developed tools to harden systems against oxygen-related fire hazards.
- WHA’s oxygen hazards and fire risk training is unsurpassed in the industry. WHA specializes in custom-tailored, technical training for oxygen systems and stresses the “why” behind the “what” related to mitigating fires in oxygen systems. Our engineers pioneered the development of oxygen safety training at NASA and ASTM International and today have advanced the content and methods well beyond any other government or industry source.
- WHA engineers have led the development of many international standards on oxygen safety. WHA engineers were founding members of the important ASTM International G-04 committee on Flammability and Sensitivity of Materials in Oxygen-Enriched Atmospheres. WHA engineers are also designated experts on ISO committees, NFPA committees, and the Undersea & Hyperbaric Medical Society.
- WHA test laboratories are unique and highly specialized for oxygen compatibility testing and material/component qualification. The WHA test facility has been utilized by clients throughout the world and is recognized among the leading test facilities for excellence in oxygen testing for both failure reconstruction testing and material, component, and system risk mitigation.
