  • HOW TO AND COMBUSTIBLE LIQUIDS SAFELY

    “combustible” liquids (see page 30). However, both classes burn readily and intensively, are explosive under certain conditions, and if not properly contained, can spread fire rapidly and uncontrollably. In this guide the term “flammable liquids” will be used to cover both flammable and combustible classes.
