Constructed from high quality steel, all SuperLoc™ buildings include built-in, leak-tested secondary containment sumps for spill containment, coal tar undercoating, and chemical and weather-resistant coatings inside and out. Maintaining compliant chemical storage is important for many reasons, including avoiding insurance costs, fines, fires and hazardous spills. SuperLoc™ flammable storage buildings are the top the of U.S. Chemical Storage line. Each building can provide years of use, as supported by our 15-year structural warranty and 1 year warranty offered on components (please see warranty disclosure for more details). All buildings can be modified with a variety of optional accessories to customize your storage solutions. Explosion control systems such as explosion relief construction can be included.

4-Hour Flammable Storage

Use SuperLoc™ hazardous storage buildings to achieve compliance and make your manufacturing and chemical storage management more efficient. Completely customizable, SuperLoc chemical storage buildings are manufactured in bi-directional 4-hour fire rated weather-resistant construction. All buildings feature mineral wool insulation installed in the wall cavity. Multiple layers of UL Classified fire-resistant gypsum wallboard encased between heavy gauge steel for maximum fire protection. Optimize your chemical storage capabilities with a variety of optional explosion proof and non-explosion proof rated, fire rated safety accessories. U.S. Chemical Storage offers options for climate control, fire suppression, mechanical ventilation and more.* Many configurations and types of storage buildings are available, including modular construction for larger sizes. All 4-hour fire-rated flammable storage buildings can meet EPA and NFPA regulations, have a standard wind load of 120 m.p.h, and can be manufactured to FM or Warnock Hersey standards. *Always consult your local authority with jurisdiction to ensure that all rules and regulations are followed, including proper setback requirements.

1. 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.

2. What size building do I need?

Building size is determined by the amount of hazardous material you are planning to store, the need for occupancy or inspection around these materials, and must take into consideration the most efficient way of moving these materials into and out of your chemical storage building.

3. What is a sump or secondary containment in reference to chemical storage buildings?

The definition of a “sump” is a pit or reservoir providing containment for spilled liquids. U.S. Chemical Storage offers leak-proof spill containment sumps in each standard model. All our sumps are tested for leaks for a 24-hour period prior to finishing. The sump is then covered by a steel or fiberglass floor grating and can even be equipped with a resistant plastic sump liner to protect against corrosive chemical accidental spills. The size of the sump is dictated by code based on the volume of liquid being stored within the building.

4. 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.
