In this episode, we discuss the scientific and regulatory definitions of flammability and combustibility. The episode details different categories of flammable and combustible liquids based on their flashpoints and boiling points, and explains the classification systems of OSHA, GHS, and NFPA. It emphasizes the importance of understanding the flashpoint and combustibility of materials in various work environments, the implications of aerosolization, and the potential for spontaneous combustion in oily rags. The discussion covers the relevance of different test methods and standards used in hazard communication and risk assessment in industrial settings.
