WHA uses many of its industry-leading analysis tools and methods to analyze hazards in non-oxygen oxidizers (nitrous oxide (N2O), nitrogen trifluoride (NF3), fluorine, ozone, compressed air, etc.), fuel gases (hydrogen, acetylene, propane, natural gas, etc.), and compressed or liquid “inerts” (nitrogen, argon, helium, etc.). Many of these fluids pose their own unique hazards, in addition to more general pressure system hazards (including pressure vessel failures, explosions, and reactions).

Non-oxygen Oxidizers.

WHA uses the same tools and methods described in the OFRA method for non-oxygen oxidizers. Particular consideration is given to the specific and inherent hazards of non-oxygen oxidizers including decomposition, violent oxidation, and toxicity. WHA’s hazard analyses are consistent with industry guidelines, standards and codes as follows:

  • Nitrous Oxide (CGA G-8.1 and G-8.2, EIGA Doc. 116/07)
  • Nitrogen Trifluoride (CGA G-14, EIGA Doc 92/03)
  • Fluorine
  • Ozone (CGA P-34)

Pressure System Hazards.

Body: Pressurized fluids of any kind are subject to common risks. Our expertise with pressure vessels and equipment allows us to provide insight into common pressure failure modes, including:

  • Overpressure Failures
  • Corrosion and Stress
  • Cryogenic Failures
  • Relief Valve Malfunction
  • Cyclical Pressurization and Vibration Failures
  • Crack Formation
