Firestop Safety and Maintenance

A firestop, or firestopping, is a material, device, or system that is installed in a building or structure to prevent the products of fires – flames, hot gases, and smoke – from spreading. Firestopping is used to seal around openings and between joints in fire-resistance-rated walls, floors, and ceilings, which themselves are designed to compartmentalize and limit the impact of fires. When firestopping is missing or installed incorrectly, flames, smoke, or hot toxic gases can spread from room to room and floor to floor and greatly worsen the outcome. Firestops, along with sprinkler systems, detection and alarm systems, and regular training, help protect buildings and their occupants. This course discusses the science of fire, the principles of fire protection, and the purpose and design of firestopping. It shares examples of NFPA-compliant and non-compliant firestopping and explains how regular inspections and maintenance can help ensure continued compliance.
