1. Do I need a fire-rated building?

There are two types of buildings to consider: fire-rated and non-fire rated steel buildings. First identify the materials to be stored and then group them by hazard. There are three steps to consider when deciding between a fire-rated and non-fire rated building. You must first determine what is to be stored and the quantity. Then you must decide where in relation to other buildings and property lines is the desired storage is to take place, and finally schedule a consult with the local authority having jurisdiction or local code expert to determine the storage building requirements. Our team at U.S. Chemical Storage has resources to help analyze your storage needs and building requirements but the final approval is made by the local authority having jurisdiction.

2. 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. This sump is then covered by a steel or fiberglass floor grating and is can be equipped with a “sump liner” of a plastic nature to provide resistance to accidental spills.

3. What size building do I need?

Building size is determined by the amount of hazardous material you are planning to store, the need, if any, for working room around these materials, and must take into consideration the most efficient way of moving these materials into and out of your chemical storage 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 occupancy ratings, construction types, and distances between both buildings. To determine the required fire separation, it is best to consult with your local code authority. If your hazmat storage building is located at distances greater than 30 feet you may not be required to have a fire-rated building.
