To outline procedures for the storage and dispensing of flammable substances.


All University personnel working with flammable substances.


This policy applies to all flammable substances which fall into the low or medium flash categories, i.e., having closed cup flash points below 200&Mac251;F (93&Mac251;C). This policy therefore includes combustible liquids.


Storage of combustible and flammable substances shall conform with the National Fire Code of Canada:

  • Flammable substances in quantities of five litres or greater shall be contained in approved safety containers, i.e., Factory Mutual or Underwriters Laboratory of Canada (ULC) approved equipment.
  • Where the quantity of flammable substances being used in any one area exceeds 50 litres, they shall be stored in an approved fire-rated storage cabinet. Not more than 250 litres in 20 litre or smaller containers may be stored in each cabinet. No other materials may be stored in the cabinet.
  • Not more than three storage cabinets may be located within a room. Flammables in quantities greater than 200 litres must be stored in a Physical Plant Department approved chemical storage room designed for that purpose. Flammable substances must be stored separately from reactive, oxidizing, or corrosive substances.
  • When dispensing flammable substances, all containers constructed from conducting material shall be grounded. All containers of flammable substances shall be W.H.M.I.S. labelled with the chemical name, "FLAMMABLE", and reference made to the availability of a Material Safety Data Sheet (MSDS).
  • Flammable substances shall not be stored in refrigerators, other than those of the safety type, nor shall they be transported on passenger elevators.
  • Approved disposal containers shall be required for the collection of waste flammable substances.
  • Smoking is prohibited in areas where flammable substances are used or stored.
