Fire stopping is a crucial component of passive fire protection that helps prevent the spread of fire, smoke, and heat through building compartments. It involves using fire-resistant materials to seal gaps, joints, or openings in walls, floors, and ceilings where services such as pipes, cables, or ducts pass through. Properly installed fire stops ensure that these penetrations do not compromise the fire safety of a building.
In the UK, fire stopping plays a critical role in maintaining the integrity of fire-resistant barriers, ensuring compliance with fire safety regulations and laws.
UK Fire Stopping Regulations
In the UK, fire stopping is governed by a range of fire safety regulations and standards to protect building occupants and reduce fire-related risks. Key regulations include:
The Regulatory Reform (Fire Safety) Order 2005 – This legislation places a legal obligation on building owners, landlords, and employers to ensure fire safety measures are in place, including appropriate fire stopping.
Building Regulations Part B (Fire Safety) – These regulations set out the requirements for fire safety in new and existing buildings, emphasising the importance of compartmentation and fire stopping to restrict fire spread.
BS EN 1366-3 and BS EN 1366-4 Standards – These British Standards outline the methods for testing the effectiveness of fire-stopping products and services, ensuring they meet strict safety criteria.
Fire Risk Assessments – Regular fire risk assessments are required to evaluate the fire safety of a building, and fire stopping is a key consideration in ensuring compliance with these assessments.
Why is Fire Stopping Important?
Fire stopping is essential because it helps:
Contain fire to its area of origin – Preventing the spread of flames and smoke to other parts of the building.
Protect escape routes – Ensuring that corridors and stairwells remain usable for longer during a fire.
Safeguard property and assets – Limiting fire damage by preventing its spread to other rooms or areas.
Comply with legal requirements – Ensuring your building meets fire safety regulations.
Types of Fire Stopping Materials
There are several types of fire stopping materials used to block penetrations in fire-resistant walls, floors, and ceilings. For example:
Intumescent sealants – These expand when exposed to heat, sealing gaps and preventing fire spread.
Fire-resistant boards and collars – Often used around pipes or ducts that pass through walls or floors.
Fire pillows – Flexible, non-combustible pillows that can be used to block gaps temporarily.
Fire-resistant compound – A cement-like material used to fill large voids in fire barriers.
Key Takeaways:
Compliance – Fire stopping is legally required in the UK to ensure fire safety in all types of buildings.
Protection – Effective fire stopping protects lives, property, and ensures the safety of escape routes.
Materials – Different fire-stopping materials are used depending on the type of penetration and the fire rating of the building.
