- Fire behavior and conditions, including: heat, energy types, chemical chain reactions, combustion chemistry, combustion products and modes of heat transfer
- The ignition characteristics of liquid, gaseous and solid fuels, flammability and BLEVE phenomenon (a combination of fire and explosion)
- Firefighting safety tips, five classes of fire: A-B-C-D-K
- Fire steps (incipient, growth, fully developed and decay)
- Fire in apartment, the effects of room contents on fire development, fire structure (Backdraft, Flashover & Rollover), thermal equilibrium and thermal stratification
