In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame. Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. The main difference between flammable and combustible liquids is the flashpoint, which refers to the lowest temperature at which the vapors generated by a liquid turn into a flammable gas and can ignite. Examples: diesel fuel, motor oil. Flammable liquids have a lower flashpoint than combustible liquids. Isopropanol / CH 3 CH (OH)CH 3. Review previous incident (s) involving fire or explosion to ensure causative and preventative actions are identified and implemented. Hazard classifications.
