WHA applies proven hazard analysis methods to evaluate oxidizers, liquefied fuels, fuel gases, inert cryogenics, and compressed fluids — helping engineers prevent accidents, protect assets, and meet compliance requirements.
These fluids pose their own unique hazards in addition to more general pressurized system hazards (including pressure vessel failures, explosions, and rapid phase transition).
Non-Oxygen Oxidizers
WHA also uses 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, including:
- Nitrous oxide (CGA G-8.1, G-8.2, and G-8.3; EIGA Doc. 176)
- Nitrogen trifluoride (CGA G-14, EIGA Doc 92)
- Fluorine (CGA G-15 and EIGA Doc 140)
- Ozone (CGA P-34)
Fuel-Gases
WHA uses its to evaluate and mitigate the unique handling, decomposition, reactivity, and flammability hazards of reactive fluids and fuels. This approach is consistent with industry practices such as NFPA 30, Flammable and Combustible Liquids Code, and other suitable best-practice standards of care. WHA evaluates the storage, handling, and use of flammable, combustible, and reactive fluids, including:
- Acetylene
- Propane
- Natural gas
- Synthesis gas
- And others
Inert Cryogenics and Compressed Fluids
WHA’s analysis methods are uniquely capable of evaluating and mitigating hazards associated with cryogenic liquids, high-pressure compressed inert fluids, and the unique potential energy releases associated with these systems. Though these systems often comprise inert liquids or gases, the potential energies for a failure can be substantial, necessitating storage and handling consistent with industry guidance from API, ASME, CGA, and NFPA 55, Compressed Gases and Cryogenic Fluids Code.
