Oxygen Fire Risk Analysis.

WHA’s formal Oxygen Fire Risk Analysis (OFRA) tool is the predominant method used to analyze oxygen fire risks in both systems and components for industries world-wide. WHA maintains a unique oxygen compatibility materials database to support our analyses, so our recommendations are grounded in real test data, not just expert opinion.

We offer fire risk analyses at several different levels, ranging from a basic Level 1 Oxygen Hazard Consult (OHC) to a formal Level 3 OFRA with a comprehensive technical report. Your customized solutions may also include specialized services like Failure Mode and Effects Analysis (FMEA), Materials Flammability Analysis (MFA), an Oxygen Cleaning Process Review (OCPR). Other specialty testing services such as oxygen compatibility testing are available when additional data is required.

Oxygen Safety Consulting.

WHA advances oxygen safety around the globe through system inspection and safety consulting. Our experienced engineers regularly review oxygen systems, components, and processes, both in-person and remotely. We often package oxygen safety inspection and consulting with technical training solutions, which can include customizable modules like oxygen cleaning.

Our capabilities

Compliance Auditing.

Compliance audits include a system inspection performed to specific industry standards. Common oxygen system and component design standards include:

  • ASTM G88
  • CGA G-4.4/EIGA 13-12
  • ASTM G93
  • CGA G4.14/EIGA 200/17
  • EASA CS-25
  • and others
Our capabilities

Hazardous Fluid Safety.

WHA uses many of its industry-leading analysis tools and methods to analyze hazardous fluids. Many of these fluids pose their own unique hazards in addition to more general pressure system hazards, including pressure vessel failures, explosions, and reactions. These fluids can include:

  • Non-oxygen oxidizers (nitrous oxide (N2O), nitrogen trifluoride (NF3), fluorine, ozone, compressed air, etc.)
  • Fuel gases (hydrogen, acetylene, propane, natural gas, etc.)
  • Compressed or liquid “inerts” (nitrogen, argon, helium, etc.)


Our Capabilities

Electrical Fire Risk.

WHA engineers have developed industry-leading tools to examine the specific hazards related to electrical failure. We can provide a fault tree analysis as well as a quantitative risk analysis and/or statistical reliability analysis.
