Flammable storage cabinets and rooms play a critical role in protecting facilities by keeping flammable liquids, aerosols, and chemicals safely separated from general storage areas, reducing the risk of accidental fires or explosions. This Hazard Alert provides guidance on proper cabinet and room design, classifications of flammable and combustible liquids according to NFPA 30, and best practices to minimize hazards associated with improper storage. Since NFPA 30 has been adopted as Colorado’s statewide minimum standard, with local governments permitted to enforce stricter requirements, understanding and following these guidelines is essential for compliance and safety.
