Fire Science Fundamentals
ASP written lesson, 10 min read. ASP Domain 4: Fire Prevention and Protection
Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Name the elements of the fire triangle, tetrahedron and dust pentagon and match each extinguishing method to the element it removes
- Explain why vapors, not liquids or solids, burn
- Define flashpoint, lower flammable limit and upper flammable limit and interpret a gas meter reading in percent of LFL
- Describe conduction, convection and radiation
- Classify fires as Class A, B, C or D using OSHA definitions
What this lesson covers
This lesson covers the fire science behind every fire prevention rule: the fire triangle, tetrahedron and pentagon, how solids and liquids actually burn, flashpoint, lower and upper flammable limits, heat transfer and the classes of fire. It matters because every control, from a safety can to an extinguisher choice, works by removing one element of the fire.
