We provide investigation of fires, explosions, and failures of systems and components using oxygen, flammable liquid and fuel gas, oxidizing and reactive fluids, or pressure equipment. From personal medical oxygen equipment in residential applications to large petrochemical plant explosions, we have the expertise and tools to determine what went wrong.
“In my career in the gases industry, when working in the fields of incident investigation and subsequent design improvement, I always found WHA both knowledgeable and innovative … The inquiring mind-set of WHA people and their facilities are leading edge and biased towards experiment and investigation, as well as being capable of ensuring product compliance with standards.”
The aftermath of fires, explosions, and other accidents is often chaotic and confusing, but our meticulous approach is designed to eliminate the mystery. WHA’s failure analysis methodology emphasizes data collection and analysis, systematic evaluation of physical evidence, and engineering analysis to reconstruct the sequence of events leading to an incident with the goal of determining corrective actions and/or liability. We provide clear answers and actionable recommendations.

Years combined experience
Incidents investigated
Countries served
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.
Our capabilities
WHA’s engineers are recognized among the world’s leading experts in fire investigations involving oxy-fuel, air-fuel, and other reactive or hazardous fluids. We’ve investigated hundreds of incidents, from small welding system fires to high-order industrial explosions. Our blast analysis and blast testing capabilities have helped set new standards and influenced the industrial, petrochemical, gas distribution industries.
Our Capabilities
WHA engineers have decades of experience designing, fabricating, operating, and testing high pressure components and systems. Our engineers are trained and knowledgeable regarding standards and codes for pressure vessels, piping, and components, and have the tools to evaluate pressure related failures.
Our capabilities
WHA has 30+ years of background and experience evaluating mechanical failures using mechanical engineering design principles, metallurgical testing, and its unique 3D microscopy to evaluate the root cause of failed mechanical equipment.
WHA also has exceptional experience and test capability in evaluating electrical sources of ignition in products and flammable gasses and oxygen enriched environments including the unique ignition mechanisms associated with ESD, Arc Tracking, and unusual component failure modes. WHA is specially equipped to help uncover the role of a suspected electrical failure in a fire incident, especially in oxygen-enriched or air/oxy-fuel atmospheres.
Our capabilities
WHA has provided forensic engineering litigation support services since 1974. Our emphasis has always been on understanding the physical evidence, the standard of care, and finding the cause of an event using the highest level of integrity and scientific/engineering reliability. The scientific method of documentation, evaluation, analysis, experimentation, observation and discovery is utilized to ensure our opinions and conclusions are founded on solid science. WHA is committed to the understanding and integrity provided by this approach and WHA strives to live up to this standard in all the services it provides.
Our capabilitiesWe don’t just investigate WHY failures occur; we’re uniquely qualified to explore HOW they can be prevented from happening again. Our investigations often lead to risk analysis and testing of related systems. We can also provide customized technical training to make sure your personnel are up to date on industry standard oxygen safety practices.
