Fire Rated Non-Occupancy RFP Chemical Storage Buildings

New Rack Fire Protect (RFP) buildings from DENIOS US are fire rated for 2 hours at 2,192 °F (1000 °C), minimizing the risk of fire spreading within the workplace. Designed in Germany, they are now manufactured in the United States for North American installations.

RFP fire-rated buildings provide safe and legally compliant storage of flammable and corrosive chemicals. Adjustable racking provides the flexibility to store up to 48 drums or 12 IBCs. Single or double-tiered designs keep dangerous chemicals organized and correctly separated. RFP buildings are built in accordance with FM Approval 6049, NFPA, OSHA, EPA-CFR 40, NBCC, NFCC and ETA/21/0642. Bi-directional fire rating provides 2-hour fire protection. They can be placed inside or outside (subject to distance requirements), making RFP suitable for the storage of sealed and closed containers of flammable and water-polluting substances.

"Manufactured using state-of-the-art technology, including new laser cutting and metal bending machinery, RFP buildings use only tested and approved components," said a company spokesperson. "These buildings have no thermal gaps, allowing heating and air conditioning equipment. Fully galvannealed panelized construction is insulated with fireproof 150 mm mineral wool panels (A class material, noncombustible). High-quality Durathane two-part RAL 9002 (Grey-White) paint helps ensure long-lasting corrosion protection inside and out. This color helps prevent the absorption of sunlight and consequent heating of the external surfaces, so the building is better protected from the influence of external temperatures."

One-piece hot dipped galvanized sump meets FM guidelines of "25% capacity rule." Each building is equipped with 3-hour fire-rated roll-up doors that are FM approved and UL-listed. Each structure meets the structural requirements for the installation location (wind and snow loads). The roof drainage design prevents water damage.

DENIOS engineers can aid in selecting HVAC technology to regulate the climate inside the RFP. Stored materials are then protected from harmful temperature fluctuations for increased shelf life. Technical ventilation provides six air changes per hour. HMI monitoring controls offer visual and audio annunciation in the case of a deviation in measured data. Easy-to-use touch panels are suitable for indoor or outdoor (NEMA 3R) operation.

Multisensor fire detectors quickly detect smoke and fire. DENIOS offers wet or dry fire suppression systems that provide added safety in the RFP. Built-in explosion protection components for internal bonding and external grounding connections are available.
