FAQ about Safety Cabinets for Flammables
How fire resistant is your Oily Waste Can?
Justrite Oily Waste Cans (OWC) are manufactured galvanized steel a fire resistant material as required by OSHA 1926.252(e). But there is more to an OWC design than that. The OWC self-closing lid limits the inside of the OWC of the oxygen that is required to support combustion. The self-closing lid guards the contents from sparks or other heat sources. Oily rags can create an exothermic chemical reaction from the polymerization of oil drying in the absence of air. This is a chemical reaction known to start fires. Always store oily rags in an approved OWC.
Why haven’t I heard about this yet?
Laws such as those driving these requirements are typically enforced once the jurisdictional authorities become aware of them. This takes time. Your local jurisdiction may not be fully aware and/or enforce the latest edition of these regulations yet. Best safety practices follow a proactive, rather than reactive, approach to compliant hazardous material storage.

Can I store gasoline and oil in the same cabinet?
Yes: OSHA 29 CFR 1910.106(d)(3)(i&ii): Design, construction, and capacity of storage cabinets (i) Maximum capacity. Not more than 60 gallons of Class l or Class ll liquids, nor more than 120 gallons of Class lll liquids may be stored in a storage cabinet.
Can I store containers in the sump of a safety cabinet?
Yes. The specifications on the sump only states it be 2-inches deep and watertight. Minimum volume is not addressed. The sump can give a safe visual indication and contain a leak before it becomes a problem, allowing the users to correct the leaking container, and clean up a spill as quickly as possible. There is nothing in writing from OSHA, NFPA, IFC, FM, or UL to limit the use of the sump on a safety cabinet for storage. That is not to say you could not limit its use for storage as an internal safety policy. An official having jurisdiction (State Fire Marshal, Building Inspector Local Fire Chief, etc.) at your site might discourage using the sump for storage. However, there is nothing otherwise to preclude storage in the sump.
What types of chemicals should be stored in these cabinets?
These cabinets are intended to store corrosive solids and liquids, flammable solids, organic peroxide formulations, oxidizer solids and liquids, pyrophoric solids and liquids, toxic or highly toxic solids and liquids, unstable (reactive) solids or liquids, and water-reactive solids or liquids. Always ensure that incompatible materials are stored in separate cabinets, and consult your local code authority for any other items in question.
Does my safety cabinet need to be grounded?
It is necessary to ground a safety cabinet if you are dispensing liquids from container(s) inside the cabinet, and the potential of an ignitable vapor is possible. This is not to preclude one from grounding all cabinets as a best practice. Please see our TechTALK on Safety Cabinet Grounding for further information.
