Expanding Foam, Fire Rated COSHH Assessment Form

A three-page COSHH Assessment Form for Fire-rated Expanding Foam, with some example text reading:

Health risks: May cause irritation and sensitisation to contact points and irritation to the eyes and respiratory system.

Skin contact: May cause sensitisation to contact points.

Eye contact: May irritate eyes.

Ingestion: May cause irritation, nausea, vomiting and diarrhoea.

Inhalation: May irritate the respiratory system.

Fire-rated expanding foam is an essential material used for sealing and filling gaps and penetrations in various construction elements, effectively preventing the spread of fire and smoke. This specialised foam is particularly beneficial in locations where compliance with fire resistance standards is crucial, such as around fire doors, window frames, and in areas where pipes and electrical conduits penetrate walls. Upon exposure to fire, the foam expands dramatically to form a robust barrier, which helps contain flames and smoke, thereby enhancing the safety of both occupants and the structural integrity of the building.

Fire-rated expanding foam plays a vital role in sealing the gaps between fire doors and their frames and around window frames. This sealing ensures that fire and smoke cannot easily enter through these vulnerable points, significantly improving the door and window's overall fire performance. It also helps maintain the intended fire rating of these barriers, which is crucial during an emergency.

This foam is widely utilised for sealing openings around pipes, electrical wiring, and other penetrations that pass through fire-rated walls and floors. By effectively closing off these penetrations, the expanding foam restricts the pathways that fire and smoke could traverse, thereby enhancing the overall fire resistance of the building envelope.

Fire-rated expanding foam is also effective for addressing small gaps and cracks in walls, ceilings, and floors. By filling these voids, the foam improves the building's fire resistance and thermal insulation properties, contributing to energy efficiency and comfort within the space.

As a comprehensive passive fire protection system component, fire-rated expanding foam works synergistically with other materials, such as firestop collars and board systems. This collaboration ensures that fire is contained within designated compartments, allowing for safe evacuation routes and effective fire suppression measures.

Beyond its fire-resistant capabilities, fire-rated expanding foam also provides excellent thermal and acoustic insulation. This dual functionality helps maintain a consistent indoor temperature and reduces noise transmission, contributing to a more comfortable environment.
