Storage of Flammables – Safely Contain Your Hazmat

Flammable liquids are present in nearly every workplace. The dangers associated with flammable liquids are usually greater than estimated. To prevent fires, hazardous materials and the storage of flammables require special techniques for storage, handling and transferring. It is necessary that all workplaces have emergency plans prior to the storage of flammables.

Below US Chemical Storage defines flammables and talks about regulations pertaining to flammable and combustible materials. See below to learn more.

Defining Flammables

The flashpoints and boiling points determine the category of a liquid. See below for a list of OSHA defined flammable liquid categories and their descriptions according to the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals.

Class IA: Liquids with flashpoints below 73F (22.8C) and boiling point below 100F (38C).

Class IB: Liquids with flashpoints below 73F (22.8C) and boiling points at or above 100F (38C).

Class IC: Liquids with flashpoints at or above 73F (22.8C), but less than 100F (38C).

Class II: Liquids that have flashpoints at or above 100F (38C), but less than 140F (93C).

ClassIIIA: Liquids that have flashpoints at or above 140F (60C), but less than 200F (93C).

 

Understanding NFPA 30 – Storage of Flammables

NFPA 30 Flammable and Combustible Liquids Code contains pertinent information for the design, construction and testing of flammable liquid storage structures, including flammable cabinets, fire-rated chemical storage buildings, and safety cans.

Flammable Safety Cabinets: According to OSHA 1910.106(d)(3)(ii), “Fire resistance: Storage cabinets shall be designed and constructed to limit the internal temperature to not more than 325 deg. F. when subjected to a 10-minute fire test using the standard time-temperature curve as set forth in Standard Methods of Fire Tests of Building Construction and Materials, NFPA 251-1969, which is incorporated by reference as specified in Sec. 1910.6. All joints and seams shall remain tight and the door shall remain securely closed during the fire test. Cabinets shall be labeled in conspicuous lettering, “Flammable – Keep Fire Away”.

Inside Storage Rooms: Under OSHA CFR 1910.106(d)(4)(i),Inside storage rooms shall be constructed to meet the required fire-resistive rating for their use. Such construction shall comply with the test specifications set forth in Standard Methods of Fire Tests of Building Construction and Materials, NFPA 251-1969…”.

Safety Cans: OSHA CFR 1920.106 (a)(29), “[A] Safety can shall mean an approved container of not more than 5 gallons capacity, having a spring-closing lid and spout cover and so designed that it will safely relieve internal pressure when subjected to fire exposure”.
