Features of Storage Buildings of Chemical Substances


Flammable liquids, chemicals and hazardous waste are safely and securely stored in chemical storage buildings which feature a leak-tight sump area at the bottom to prevent leakage and contamination on the surrounding storage area. Basically, chemical storage buildings are customized to accommodate any type of container, according to the volume capacity of chemicals that are normally stored.


The strict regulations for chemical storage buildings are based on a system of inspection and accredited from Factory Mutual System Approval and the FB Approved fire rated wall and roof design, that’s why almost all chemical storage buildings are fire-rated designed and approved. Fire ratings upgrade mean the time duration in which a structure can withstand the damage of fire, therefore, fire-rated storage buildings are constructed following these criteria: standard buildings must pass the 2-hour and 4-hour fire ratings upgrade, walls must pass the 2-hour and 4-hour fire ratings upgrade, and roofs must pass the 1.5-hour and 3-hour fire ratings upgrade. To meet with the standard requirements, all fire-rated buildings must be equipped with hydraulic operated self-closing, fire-rated doors and fire damper protected vents.

Chemical storage buildings are constructed out of a 16 gauge galvanized steel for a 12 drum capacity, while larger buildings are constructed of a 12 gauge galvanized steel. The standard sump, bottom part of the storage building which functions as reservoir, is constructed of heavy gauge steel with leak tight seams, while the interior of the sump is coated with corrosion resistant material, a high-density polyethylene liner. If the building is designed to store four 55-gallon drums, the sump can only contain 55 gallons, this, therefore, points to the standard capacity of the sump, which must be at least 25% of the liquid storage capacity of the building.
