Hazardous materials - Flammable liquids

  1. Liquids, liquid mixtures, and solutions or suspensions that include solid matter (which refers to paint, varnish, lacquer, and other materials,) that produce flammable vapor at temperatures not higher than 60.5 degrees centigrade (141 degrees Fahrenheit) for the airtight container test, and 65.6 degrees centigrade (150 degrees Fahrenheit) for the open container test.Provided, however, flammable liquids which are categorized into other hazarous materials by its hazarous nature shall not be included. The above temperature is generally called "flash point".
  2. Among the liquids mentioned in (1), ones with flashpoints that exceed 35 degrees centigrade (95 degrees Fahrenheit) need not be considered flammable liquids, provided that
    • They do not burn even if the method to test the flammability of the substances mentioned in 3 is used;
    • They have combustion points that exceed 100 degrees centigrade (212 degrees Fahrenheit) based on ISO 2592; or
    • They are miscible solutions that include water content exceeding 90% in weight.
  3. All liquids must be considered flammable liquids if they are to be transported at temperatures equal or higher than their flashpoints.
  4. Substances that are transported at elevated temperatures and produce flammable vapor at the possible highest temperatures (to which they will be probably exposed during transport) or even lower temperature must be also considered flammable liquids
  5. Examples: benzene, gasoline, alcohol, flammable solvents and synthetic cleaners, flammable paint, flammable varnish, stripping agents, and thinner
