Pre-Engineered Flammable Lockers

Pre-engineered, quick delivery outdoor lockers can offer compliant storage for hazardous chemicals stored in small volume containers. Pre-engineered flammable lockers are available in 2- or 4-hour fire-rated constructions. These fire-rated structures keep hazardous inventory close to facilities for increased manufacturing efficiency, while protecting flammable and combustible inventory.

Small Quantity Flammable Storage Lockers

All flammable lockers are constructed with heavy-gauge galvanized steel grating floors, secondary containment sumps, natural ventilation and additional accessories to keep personnel and facilities compliant. Suitable for storing 55-gallon drum containers, lockers are available in a variety of standard sizes ranging from 2 to 16 drum storage capacity. All lockers are FM approved and can meet EPA and NFPA regulations.

Storing bulk chemicals can lead to a disaster if improper chemical storage buildings are used. Not every building is safe for chemical storage.

1. How do I comply with regulations?

Chemical storage buildings manufactured by U.S. Chemical Storage are designed to get your operation compliant. Contact one of our technical sales engineers to learn how we can find the best solution for your compliance needs. You will also want to learn more about specific chemical storage requirements in your specific area by contacting your local “Authority Having Jurisdiction” (AHJ) who could be a local fire marshal, a municipal code official, or a city environmental department.

2. Do I need a fire-rated building?

First consult the Safety Data Sheet (SDS) to determine the type of chemical you’re storing and any storage requirements listed. There are two main classifications of buildings to consider: fire-rated and non-fire-rated steel buildings. There are three main questions you should answer before engineering or design can begin on your building: what is to be stored, how much of it is being stored, and where is the location it will be stored? You will also need to consult with your local “Authority Having Jurisdiction” (AHJ) or local code expert to determine your area’s specific storage building requirements. Our team at U.S. Chemical Storage has a wealth of knowledge, experience, and resources to help analyze your storage needs, but the final approval is made by the local AHJ, so you will need to ultimately ask them about your requirements early in the planning process.

3. How will location affect my building type?

Location of the building can be either inside another building or outside to fit your needs. Fire Separation, which is the amount of fire rating required between two occupancies, or the separation distance between those two occupancies, is determined by the type of chemical or hazard being stored, and distances between buildings, egress pathways, or environmental features. To determine the required fire separation, it is best to consult with your local code authority. Inside another building or within 10 feet of another building, you’ll be required to have a 4-hour fire rating. If your hazmat storage building is located at distances 30 feet or greater your building may not be required to have a fire rating at all.
