Section 437-004-1430 - Sources of Fire(1) Definitions. These terms are used in Subdivision 4/L Fire: (a) Closed container - A container sealed with a lid or other device that prevents the loss of liquid or vapor at ordinary temperatures. (b) Combustible - A substance or material that is able or likely to catch fire and burn. (c) Explosive - something capable of causing damage to the surroundings by chemical reaction. (d) Flammable - Something capable of being easily ignited, burning intensely or having a rapid rate of flame spread. (e) Flammable liquids - are liquids having a flash point at or below 199.4 degrees F. (93 degrees C.) As defined in the globally harmonized system of classification and labeling (GHS) adopted in OSHA's Hazard Communication Standard, flammable liquids are divided into four categories. NOTE: Examples of some common flammable liquids are:
Category 1: Diethyl ether (solvent sometimes used in starting fluid).
Category 2: Gasoline (Benzene, Ethanol).
Category 3: Kerosene, Stoddard Solvent.
Category 4: Diesel fuel, Naphthalene.
NOTE: Additional information can be found in Division 4/B, 437-004-0100 Universal Definitions.
(2) Store combustible waste material, including oily rags in covered metal receptacles. (3) If using electric lights, equipment, and wiring where there may be flammable or explosive gases, vapors, mists, dust or fibers they must comply with the State Electrical Specialty Code. NOTE: See additional electrical requirements in Division 4/S, OAR 437-004-3075 Agricultural Buildings with Special Hazards.
(4) Locate internal combustion engines so that there is a clearance of at least 6 inches between exhausts and exhaust piping and combustible material. (5) Do not allow smoking, open flames, the use of spark-producing devices or tools not approved for use in such areas, and other sources of ignition: (b) When servicing fuel systems for internal combustion engines. (c) When receiving or dispensing flammable liquids. (d) Where using flammable liquids. (e) Where storing flammable liquids. (f) Areas that may have flammable or explosive gases, vapors, mists, dust, fibers or flyings. NOTES: Other sources of ignition include cutting and welding; grinding hot surfaces; frictional heat; static, electrical and mechanical sparks; spontaneous ignition including heat producing chemical reactions; and radiant heat. There are more detailed standards for: The use and storage of flammable liquids in 4/H, OAR 437-004-0720; The use of liquefied petroleum gas (LPG) in 4/H, OAR 437-004-0780 and 437-004-0790; The prevention of fire prevention standards for welding operations are in 4/Q, OAR 437-004-2310.
