Consequence Analysis


Save 25% when you register three or more attendees. Team Discount cannot be combined with any other discounts or promotions.

This course covers current regulatory requirements, including source term modeling (release rate, pool formation and evaporation, and aerosol formation methods); atmospheric dispersion modeling (meteorological concepts and passive and dense vapor cloud dispersion methods); fire modeling (pool fire, jet fire, boiling liquid expanding vapor explosion [BLEVE] fireball, and flash fire methods); explosion modeling (vessel rupture, BLEVE, vapor cloud explosion, and confined explosion methods); data and correlations for evaluating personnel injury and facility/equipment damage resulting from toxic exposure, fires, and explosions; public and commercial software available for performing consequence analyses; and risk analysis methods.


Who Should Attend this course?
  • Those who need a thorough understanding of consequence analysis techniques to comply with EPA's risk management program rule (40 CFR 68)
  • Those who use consequence analysis techniques to evaluate accidents for documented safety analyses
  • Those who use consequence analysis as an integral part of QRAs and SVAs
  • Those who develop plant/community emergency response plans using consequence analysis techniques
  • Participants should have the equivalent of a bachelor's degree in science, engineering, or mathematics (attendees should bring a scientific calculator to the course)
what will i learn in this course?
  • Gain a fundamental understanding of consequence analysis terminology, techniques, and software used in the industry
  • Learn the assumptions and limitations of the various techniques (when to apply them and when not to)
  • Understand and be equipped to use consequence analysis techniques in a variety of applications (SVAs, OCAs, QRAs, facility siting studies, emergency response planning, etc.)
  • 3.5 CEUs, 3.5 COCs, 5.85 CM, ABIH approval #10-246
Duration: 5 days
