Gas Explosion

Gexcon offers clear and objective scientific insights to unravel the complexities of gas explosion incidents, assisting in dispute resolution.

Preventing future incidents requires learning from past failures and taking corrective actions.

For over four decades, Gexcon has been involved in the assessment of safety concerns associated with vapour cloud explosions, gas explosions, and aerosol explosions.

Leaders in various process industries, safety engineers, attorneys, and insurance adjusters consistently rely on Gexcon's expertise for incident investigations, including large loss cases involving gas explosions.

Gexcon provides a comprehensive range of services for gas explosion investigations, covering site inspections, cause determination and analysis, testing, incident reconstruction using advanced tools, and expert witness testimony.

Count on our expertise in gas explosions

Gexcon's team of gas explosion experts comprises licensed Certified Fire and Explosions Investigators (CFEI) and Professional Engineers (PE) who bring extensive experience in investigating a broad spectrum of explosions, ranging from residential building and small vessel incidents to large-scale events within various process industries involving propane, natural gas and flammable liquids.


Gexcon performs analysis to identify leak locations and assess their extent. Our methods involve soil sampling for fuel gas, pressure testing, pipeline excavation, combustion control evaluation, and the use of ground-penetrating radar to trace underground migration routes. Additionally, our team is experienced in various sample collection methods, such as the determination of odourant levels and chemical composition for LPG.


Our experts proficiently apply fundamental scientific principles to gas explosion investigations, aligning with the guidelines specified in NFPA 921 (Guide for Fire and Explosion Investigations).


Furthermore, Gexcon uses the advanced modelling tools to create an accurate representation of incident sequences.
