Chemical Storage Reagent Cabinets

Chemical storage reagent cabinets

Specialized types of storage reagent cabinets must be used in laboratories in order to separate incompatible chemicals from one another and to ensure safe storage. All chemicals must be stored in a secure container, preferably within enclosed reagent cabinets. Periodically check shelves and supports in all chemical storage reagent cabinets for corrosion or other signs of damage.

Flammable chemical storage reagent cabinets

Flammables not in active use should be stored inside a flammable chemical storage cabinet. Flammable storage cabinets should be used for all labs that use flammable chemicals. No more than 10 gallons of flammable chemicals can be stored outside of a flammable cabinet.Chemical storage reagent cabinets,chemical reagent cabinets, chemical reagent storage cabinet

The cabinet design must meet National Fire Protection Association (NFPA) 30 & Occupational Safety and Health Administration (OSHA) 1910.106 standards. The purpose of designing to these codes is to minimize the risks caused by a fire following the combustion of flammable materials that were exposed to a source of flame or spark. Flammable cabinets have features such as flame arresters, leak-proof sills, and highly visible signage.

Chemical Flammable storage cabinets are designed to protect the contents from the heat and flames of external fire rather than to confine burning liquids within. They can perform their protective function only if used and maintained properly. Always make sure that the door properly and fully closes.

Cabinets are typically designed with double-walled construction and doors which are two inches above the base (the cabinet is liquid-proof up to that point). Cabinet doors should be self-closing.

Metal Flammable Reagent Storage Cabinet Features Include:

Bottom, top and sides of cabinet must be at least No. 18-gauge sheet iron

Cabinet must be double walled with one and one-half inch airspace

Joints must be riveted, welded or made tight by some equally effective means

Door must have a three-point latch

Door sill must be raised at least two inches above the cabinet bottom to retain spilled liquid within the cabinet

Wood Flammable Storage Cabinet Features Include:

Bottom, top and sides of cabinet must be constructed of exterior-grade plywood at least one inch thick

Plywood must not break down or delaminate under fire conditions

Joints shall be rabbeted and fastened in two directions with flathead wood screws

Acid Reagent Storage Cabinets

Acids should be kept in an acid chmeical storage cabinet specially designed to hold them. Such cabinets are made of plastic or metal coated with epoxy enamel to protect against corrosion. If not provided as part of the cabinet, use polyethylene trays to contain small spills. If your lab does not have an acid cabinet, acids can be stored in a wooden cabinet inside a plastic tub for containment. Nitric acid must always be stored away and separate from other acids.Leave a Message
