OSHA Standards and Requirements for Safe Handling, Storing and Dispensing of Flammable Liquids

Satisfying OSHA Standards for Plant Safety
This section should prove of special interest to you and be helpful in selecting the particular safety container or device that you need to meet a specific OSHA requirement.

Safety Cans
1926.152 Flammable and combustible liquids.
1926.152(a)(1)
(a) General requirements. (1) Only approved containers and portable tanks shall be used for storage and handling of flammable and combustible liquids. Approved metal safety cans shall be used for the handling and use of flammable liquids in quantities greater than one gallon, except that this shall not apply to those flammable liquid materials which are high viscid (extremely hard to pour), which may be used and handled in original shipping containers. For quantities of one gallon or less, only the original container or approved metal safety cans shall be used for storage, use, and handling of flammable liquids.

Safety Storage Cabinets
1926.152 Flammable and combustible liquids.
1926.152(b)(1) - (b) Indoor storage of flammable and combustible liquids. (1) No more than 25 gallons of flammable or combustible liquids shall be stored in a room outside of an approved storage cabinet.

1926.152(b)(2)(ii & iii) - (b) Indoor storage of flammable and combustible liquids. (2) Quantities of flammable and combustible liquid in excess of 25 gallons shall be stored in an acceptable or approved cabinet meeting the following requirements. (ii) Approved metal storage cabinets will be acceptable. (iii) Cabinets shall be labeled in conspicuous lettering, "Flammable-Keep Fire Away".

1926.152(b)(3) - (b) Indoor storage of flammable and combustible liquids. (3) Not more than 60 gallons of flammable or 120 gallons of combustible liquids shall be stored in any one storage cabinet. Not more than three such cabinets may be located in a single storage area. Quantities in excess of this shall be stored in an inside storage room.

Disposal Equipment
1910.106 Flammable and combustible liquids.
1910.106(e)(9)(iii) - (e) Industrial plants-(9) Housekeeping-(iii) Waste and residue. Combustible waste material and residues in a building or unit operating area shall be kept to a minimum, stored in covered metal receptacles and disposed of daily.

1926.252 Disposal of waste materials.
1926.252(e) - (e) All solvent waste, oil rags, and flammable liquids shall be kept in fire resistant covered containers until removed from worksite.

Drum Storage and Dispensing Equipment
1910.106 Flammable and combustible liquids.
1910.106(d)(2)(ii) - (d) Container and portable tank storage-(2) Design, construction, and capacity of containers-(ii) Emergency venting. Each portable tank shall be provided with one or more devices installed in the top with sufficient emergency venting capacity to limit internal pressure under fire exposure conditions to 10 p.s.i.g., or 30 percent of the bursting pressure of the tank, whichever is greater.

1926.152 Flammable and combustible liquids.
1926.152(e)(2) - (e) Dispensing liquids. (2) Transfer of flammable liquids from one container to another shall be done only when containers are electrically interconnected (bonded).

1926.152(e)(3) - (e) Dispensing liquids. (3) Flammable or combustible liquids shall be drawn from or transferred into vessels, containers, or tanks within a building or outside only through a closed piping system, from safety cans, by means of a device drawing through the top, or from a container, or portable tanks, by gravity or pump, through an approved self-closing valve. Transferring by means of air pressure on the container or portable tanks is prohibited.

Definitions
1910.106 Flammable and combustible liquids.
1910.106(a)(19) - (a) Definitions. As used in this section: (19) "Flammable liquid" means any liquid having a flashpoint below 100°F. (37°C.), except any mixture having components with flashpoints of 100°F. (37°C.) or higher, the total of which make up 99 percent or more of the total volume of the mixture. Flammable liquids shall be known as Class I liquids. Class I liquids are divided into three classes as follows:

(i) Class IA shall include liquids having flashpoints below 73°F. (22.8°C.) and having a boiling point below 100°F. (37.8°C.).
(ii) Class IB shall include liquids having flashpoints below 73°F. (22.8°C.) and having a boiling point at or above 100°F (37.8°C.).
(iii) Class IC shall include liquids having flashpoints at or above 73°F. (22.8°C.) and below 100°F. (37.8°C.).

1926.155 Definitions applicable to this subpart.
1926.155(l) - (l) "Safety can" means an approved closed container, of not more than 5 gallons capacity, having a flash-arresting screen, spring-closing lid and spout cover and so designed that it will safely relieve internal pressure when subjected to fire exposure.
