Product Description

The design of the building will also be affected by whether or not you will be dispensing from containers stored in the building. Explosion relief panels are required for buildings that store and dispense Class IA liquids and that dispense Class IB liquids. Otherwise, an explosion relief panel is not required. 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: Can outdoor chemical storage buildings be moved from one location to another? 

A: Yes. Outdoor chemical storage buildings are designed to be portable. When moving a building to a new location, be sure to confirm that the new location meets all required local codes. A building can also be moved indoors if needed. Buildings for flammable liquid storage being relocated indoors should have a continuous ventilation system that is exhausted to the outdoors, a four-hour fire rating, a fire suppression system and explosion relief panels directed towards a safe exterior location. Also, in most cases when storage is indoors and a sprinkler system is installed, the containment sump is required to be large enough to hold 100% of the volume of the largest container stored or 10% of the combined total volume of all of the stored containers, whichever is larger, plus the additional volume of the water discharged by the sprinkler system in 20 minutes. 

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.
