Confined explosions in enclosed buildings have caused at least 20 fatalities and 123 injuries since 1998, yet PHAs and QRAs routinely fail to account for them adequately. This webinar presents a systematic review of CSB incidents and introduces quantitative methods to better assess and integrate these critical hazards into standard risk analysis. This webinar was based on a presentation from the 2026 AIChE Spring Meeting & 22nd Global Congress on Process Safety.
