This product is suitable for storing drums and IBC large container; Apply in segregated storage of hazardous chemicals container, indoor or production workshop. Also use as outdoor container.

Safely storing hazardous materials and wastes is a necessity for many companies.Outdoor Chemical Storage Buildings provide an effective solution to fulfill this need. The National Fire Protection Association (NFPA) defines an outdoor chemical storage building as "a prefabricated structure, manufactured primarily at a site other than the final location of the structure, and transported completely assembled or in a ready-to-assemble package to the final location." These buildings provide an economical means of storage and secondary containment because they eliminate the expense of constructing permanent structures. They also offer the additional benefit of being portable, allowing the buildings to be relocated should the need arise.

When selecting outdoor chemical storage buildings your choice will depend on the materials to be stored, how the building will be used, the volume of the materials being stored and the location of the building and design requirements.

If the materials to be stored are either flammable or combustible, you will need a building that meets the NFPA Code 30, Uniform Fire Code (UFC) Articles 79 and 80, or an equivalent local code. Check with the authority having jurisdiction (AHJ) to determine which code is locally enforced.

The class of the flammable-combustible material (refer to NFPA Code 30) can also dictate what type of building construction is required. Class I, II, or III flammable and combustible liquids will require either a non-combustible building or a fire-rated building. Non-combustible buildings are constructed of non-combustible material (such as steel), whereas a fire-rated building is constructed of non-combustible materials and includes fire resistant insulation in the walls. Fire-rated buildings are further divided into categories based on the fire resistance of the walls, roof and openings (doors and vents).

With the 2012 revision to the Occupational Safety and Health Administration’s (OSHA’s) Hazard Communication standard and the adoption of portions of the Globally Harmonized System of Classification and Labeling of Chemicals, flammable liquids are now either Category 1, 2, 3, or 4 flammable liquids. The NFPA fire codes still identify liquids as flammable IA, IB, IC or combustible II, IIIA and IIIB liquids. Information regarding the flammability of the chemical you are storing is located in Section 9 of the Safety Data Sheet (SDS).

The interior of the building should accommodate the number of containers required in a single layer and have adequate sump capacity to comply with the Environmental Protection Agency (EPA) Secondary Containment Requirements (40 CFR 264). To meet this regulation, the sump containment should be large enough to hold 100% of the volume of the largest container stored in the building or 10% of the total volume of all containers stored in the building, whichever is larger.

Q: Is there a difference between a chemical storage building and a chemical storage locker?

A: Yes. A chemical storage locker is usually smaller in size and generally doesn’t allow workers to enter the structure. Approval of storage lockers is limited to outdoor use only.
