Process Safety Engineering

Exponent is a leading consulting firm in the investigation and prevention of chemical and industrial process accidents, with over 50 years of history in incident investigation, failure analysis, and safety consulting. The wealth of knowledge gained from thousands of process-safety-related investigations in industrial, chemical, oil, and gas facilities provides a valuable reservoir of lessons learned. Exponent’s consultants assist clients in evaluating risk, investigating failures and process upsets, and identifying and evaluating preventive measures in a manner sensitive to both risk and financial sustainability. Exponent’s multi-disciplinary teams of professionals leverage this knowledge base, along with their expertise in the various aspects of plant design, implementation, and operation, to assist clients’ efforts to understand the limits and capabilities of their process plants and perform root-causes analyses.

Our Approach

Exponent combines its experience from reactive failure analysis with its interdisciplinary internal network, substantial laboratory facilities, and over 900 technical consultants to tackle the most complicated process safety incidents and challenges that clients face. Our project experience ranges from the analysis of small equipment failures to investigation of the catastrophic loss of entire production facilities. Exponent’s consulting staff is located in 24 offices in the United States and 7 offices internationally, giving Exponent the ability to respond quickly and efficiently to problems across the globe.

Our capabilities and expertise are further evidenced by our participation, as chairs and committee members, on many of the industrial standards and guidance documents that plant operators look to for process safety guidance (e.g., NFPA, ASME, ASTM, API, ISO, and the Hydraulic Institute). Our professionals publish numerous papers in their fields of expertise, and Exponent is also a corporate member company of the Center for Chemical Process Safety (CCPS).
