This SACHE product covers the fundamentals of explosions and some practices necessary for preventing explosions. The 35 minute video includes:
- Pictures showing the consequences of explosions.
- Discussion of definitions, such as auto-ignition temperature (AIT), lower and upper flammability limits (LFL/UFL), minimum ignition energy (MIE), limiting oxygen concentration (LOC), flash point (FP), etc.
- The distinction between physical and chemical explosions.
- Detailed discussions covering boiling liquid expanding vapor explosions (BLEVES), dust explosions, deflagrations, and detonations.
The video can be used as an introduction to a lecture on explosions, or given to students for self study prior to a more detailed discussion in a classroom setting. This product can be used in universities or industrial training sessions. In the university, it can be used in various courses such as design, thermodynamics, kinetics, or a safety course. In industry, it can be used for new engineers as an introduction to chemical process safety.
The recommended practices and related references include:
- Explosion prevention technology, such as reliefs, venting devices, etc.
- Codes and Standards – NFPA, ASME, and API.
- Textbooks, CCPS Guidelines, Periodicals, Short Courses, and SACHE materials.
