As part of these capabilities, WHA engineers and scientists provide expert witness services in support of their investigations and analyses.
Hazard and Fire Risk Analysis
Analyzing and mitigating hazards and fire risks associated with hazardous fluids is critical to ensuring the inherent safety of a given system. Many industries world-wide rely on WHA's background, training, and experience to evaluate the fire risks associated with various hazardous fluids including gaseous and liquid oxygen (GOX & LOX), non-oxygen oxidizers (nitrous, nitrogen trifluoride, fluorine, ozone, compressed air), fuel gases (hydrogen, acetylene, propane, natural gas) and compressed or liquid "inerts" (nitrogen, argon, helium).
WHA’s engineers have worked with international standards organizations (ASTM, CGA, EIGA, NFPA, SAE, ISO, and others) to develop and implement new standards that govern safe design practices and fire risk analysis methods to minimize the risk of fire in oxygen and oxy-fuel gas systems.
WHA works with clients to apply these methods to components and systems for the purposes of basic safety audits, standards compliance, or full-scale formal fire risk analysis.
WHA’s formal Oxygen Hazards & Fire Risk Analysis (OHFRA) tool, based on industry standards, has now become the predominant method used to analyze oxygen fire risks in oxygen components and systems for industries world-wide.
Standard & Custom Testing
WHA's test facilities are internationally recognized for the range and depth of their testing capabilities and their comprehensive research services. Our Test Facility is compliant with ISO 17025. WHA conducts a large variety of standard tests including material and component testing in various fluids such as oxygen, inert gases, fuel gases, and non-oxygen oxidizers.
Among the many quality testing and research services that WHA provides, there are several that are offered commercially in the United States only by WHA. Many state-of-the-art specialty tests available are unique to WHA.
Based on specific customer requirements and in response to evolving industry-specific demands, new and innovative testing systems are routinely developed. Along with its own facility, WHA through a unique industry liaison relationship with NASA's White Sands Test Facility makes available testing capabilities that exceed WHA's in-house capabilities.
The forensic engineering services that WHA performs often lead to reconstruction support testing. Where applicable, standardized tests are performed, but when appropriate, customized testing is used to provide answers to our client's questions.
WHA is renowned for its quality custom-tailored testing and its ability to deliver fast results. Whether fire, mechanical, electrical or chemical testing is required, WHA has the capability, experience and resources to provide professional and comprehensive results.
WHA specializes in custom-tailored, technical training for oxygen and hydrogen systems. We believe in teaching the “why” behind the “what,” empowering students to better understand the systems on which they work.
WHA’s unique instructional philosophy better equips students to respond to their job-related safety challenges. WHA has spent almost three decades developing the expertise and background represented in our course offerings.
Our training courses are based on the latest guides and practices from industry standards from ASTM, CGA, EIGA, NFPA, SAE, ISO and others. We know the industry standards because we help write them by actively participating in these standards organizations.
Safety principles for oxygen are at the heart of what we teach. We use the simple fire triangle illustration to effectively communicate basic fire principles that become the basis for fire risk mitigation.
The key words we use to create a safe environment have now become a standard in industry: Maximize, Minimize, Utilize. These core concepts are taught in every course we provide, from our Level 1 introductory hazards awareness courses up to our Level 4 engineering design and fire risk analysis courses. WHA currently offers four different levels of training and three different formats (on-site, eTraining, and webinars) to meet industry needs.
Our instructors are knowledgeable in oxygen testing standards worldwide, are experienced in forensic investigation techniques and have taught courses in almost every industry that utilizes oxygen. Our course instructors are industry-leading experts in the fields of oxygen safety, design methodology, hazards analysis, and fire risk mitigation. We can effectively train on design methods, risk analysis techniques, and good practices for system assembly, operations and maintenance at every level of competency.
WHA has a new precision clean room to provide commercial precision cleaning services for oxygen equipment. WHA has been performing oxygen precision cleaning for over 15 years and currently cleans up to 10,000 piece parts per month.
WHA can meet various industry oxygen cleaning specifications such as those listed in ASTM G93, ISO 15001, CGA G4.1 and SAE ARP1176. Our oxygen cleaning process is validated using quantitative verification techniques following on ASTM methods.
Our oxygen cleaning verification services can also help evaluate your own oxygen cleaning or support contamination analyses to quantify and characterize contamination.
