Oregon Administrative Rules › Chapter 437 - DEPARTMENT OF CONSUMER AND BUSINESS SERVICES, OREGON OCCUPATIONAL SAFETY AND HEALTH DIVISION › Division 4 - AGRICULTURE › Section 437-004-0720 - Flammable and Combustible Liquids

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Definitions:
(a) Approved - See Universal Definitions in
			 4/B, OAR 437-004-0100.
(b) Closed
			 container - A container sealed with a lid or other device that prevents the
			 loss of liquid or vapor at ordinary temperatures.
(c) Combustible - A substance or material
			 that is able or likely to catch fire and burn.
(d) Combustible liquids - See definition of
			 "Flammable liquids" below.
NOTE
: When Oregon OSHA revised the Hazard
				Communication Standard to align with the Globally Harmonized System (GHS) of
				classification and labeling of chemicals, the term "combustible liquid" was
				eliminated. However, the term is still used by the National Fire Protection
				Association (NFPA) and by the Oregon State Fire Marshal. The NFPA system
				classifies some chemicals as "combustible liquids" that OSHA classifies as
				"flammable liquids."
(e)
			 Explosive - something capable of causing damage to the surroundings by chemical
			 reaction. Also, see Universal Definition in 4/B, OAR 437-004-0100.
(f) Flammable - something capable of being
			 easily ignited, burning intensely, or having a rapid rate of flame spread.
			 Also, see Universal Definitions in 4/B, OAR 437-004-0100.
(g) 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 as follows:
(A) Category 1
			 includes liquids that have a flashpoint below 73.4 degrees F. (23 degrees C.)
			 and have a boiling point at or below 95 degrees F. (35 degrees C.)
(B) Category 2 includes liquids that have a
			 flashpoint below 73.4 degrees F. (23 degrees C.) and have a boiling point above
			 95 degrees F. (35 degrees C.)
(C)
			 Category 3 includes liquids that have a flashpoint in a temperature range from
			 at or above 73.4 degrees F. (23 degrees C.) to at or below 140 degrees F. (60
			 degrees C.)
(D) Category 4
			 includes liquids that have a flashpoint in a temperature range from above 140
			 degrees F. (60 degrees C.) to at or below 199.4 degrees F. (93 degrees C.)
NOTES:
See Appendix A to OAR 437-004-0720 Flammable Liquids for a comparison of the GHS/Hazard Communication
				classification system with the NFPA classification system. Examples of
				flammable liquids include: Category 1: Diethyl ether (solvent used in some
				starting fluids) Category 2: Gasoline, Benzene Category 3: Kerosene, Stoddard
				Solvent
Category 4: Diesel fuel
(h) Portable tank - A closed container with a
			 liquid capacity more than 60 U.S. gallons (230 liters) and not intended for
			 fixed installation.
(i) Safety can
			 - An approved closed container, of not more than 5 gallons (20 liters)
			 capacity, with a spring-closing lid and spout cover, and designed so that it
			 will safely relieve internal pressure when subjected to fire.
