This symbol with the word 'explosive' denotes a substance which may explode under the effect of a flame or if subjected to shocks or friction. A material’s ability to ignite is dictated by the strength of bonds between molecules within the substance and the ease of oxidation. It would be convenient if all substances could be categorized as either flammable or non-flammable but, unfortunately, a significant proportion of substances fall into the category of burning under certain conditions. Inflammable substances have higher fume strain because of which flash point diminishes and combustibility increment in inflammable substances are exceptionally flammable. The main difference lies that flammable substances catch fire easily, and inflammable substances are not as easy to ignite, i. flammable substance means any flammable or combustible solids or liquids or flammable gas; flammable substance means any material or substance defined as "flammable" or as a "combustible fiber," " combustible liquid ," " flammable liquid ," or "flammable solid" by the fire code adopted under section 3737.

Combustible materials typically require higher temperatures to ignite than flammable ones. Per OSHA, workplace environments that contain flammable vapors must be equipped with ventilation capable of reducing the concentration of the substance to less than 10% of the LEL. This varies with different flammable liquids. 3. Combustibility is a measure of how easily a substance bursts into flame, through fire or combustion. It is a critical property to consider in designing and handling materials, particularly in industries that involve manufacturing, transportation, and storage of flammable substances such as chemicals, fuels, and gases.
