June 23, 2016The Transient Reactor Test (TREAT) Facility at Idaho National Laboratory's Materials and Fuels Complex (MFC) needs flammable and combustible liquids storage space. The proposed action is to procure an outdoor, prefabricated chemical storage building designed for storage of 55 gallon drums containing flammable or combustible liquids. The facility would be a hazardous material storage building made with double-walled galvannealed steel with 3" of insulated air space for extra strength and safety. The double-walled building has been tested for tornado resistance, withstanding F-4 tornado force winds of 250 mph. The outer wall of the chemical storage center would be welded 16 or 12 gauge steel. The inner wall would be constructed of 20 gauge steel. The hazardous materials storage building would include a 12 gauge welded steel liquid-tight sump, removable galvanized steel grating and safety floor planking. Convection vents would be located throughout. Twelve 12 gauge galvanized steel forklift channels to assist in transporting the building would be provided. National Fire Rating (NFR) warning labels, ratings and instructions would also be included. The facility would be finished in chemical, corrosion and ultra-violet (UV) resistant paint. The facility would meet National Fire Protection Association (NFPA) code 30 and would comply with Occupational Safety and Health Administration (OSHA) and Environmental Protection Agency (EPA) regulations.
