Our Mission.

For over 30 years, WHA International (formerly Wendell Hull & Associates) has been helping clients understand, evaluate, and mitigate hazards and fire risks associated with oxygen, hydrogen, and other hazardous fluids. Our in-depth experience with testing and forensic investigation equips us to provide highly-specialized services of failure analysis, hazard analysis, standard and custom testing, technical training, and oxygen precision cleaning.

Our Background.

WHA was founded in 1987 with a special emphasis in failure analysis and forensic engineering. From the early years, the company’s focus was to provide just resolution of forensic engineering disputes, using the scientific method for testing and evaluation.

Before long, numerous industries began looking to WHA not just for answers about past incidents, but for critical information on how to stay safe around oxygen and other hazardous fluids. WHA’s capabilities expanded organically beyond failure analysis to include our current suite of comprehensive consulting, training, and testing services, all focused on oxygen safety. As the hydrogen economy continued to grow in the 21st century, WHA began to participate in notable projects and accident investigations around the world, adding hydrogen as an additional core area of expertise.


Oxygen Specialty.

Oxygen safety came into the spotlight in 1967 following the tragic death of NASA’s Apollo 1 crew members. Our founders built their careers with NASA and later brought their experience to the commercial sector through WHA International.

From the beginning, our engineers have been uniquely equipped to address the specific safety concerns of oxygen, and WHA remains a respected authority in oxygen safety today. Our engineers are intimately familiar with international standards governing the use of oxygen, because they have helped write many of the standards,and routinely contribute to organizations such as ASTM, CGA, EIGA, NFPA, NASA, SAE, and ISO.

Hundreds of companies worldwide rely upon our cutting-edge Oxygen Fire Risk Analysis (OFRA) method. Our approach is consistent with industry standards for performing oxygen hazards analysis on systems and components per ASTM (G 88, G-63, G-94, and others), CGA (G-4.4), EIGA (IGC 13/12, 200/17), ISO (ISO 15001) and NASA (TM-2007-213740).
