Compartmentation Surveys

Fire Compartmentation Surveys

In-Line Safety provide fire compartmentation surveys with expert advice to comply with fire safety legislation.

Definition of Compartmentation is… Division into separate sections or units.

In a building where the floors and walls are designed as fire compartments in order to protect the occupants from the spread of fire by containing it in the compartment (origin of fire) for a period of time or until rescue can be affected.

Our Fire Compartmentation Surveys are designed to give you a full assessment of your fire compartmentation requirements for buildings that come under Article 17 of the Regulatory Reform (Fire Safety) Order 2005.

In-Line Safety consultants are registered with the FPA (Fire Protection Association) and also the ASFP (Association for Specialist Fire Protection). They are all NEBOSH qualified and all consultants carry their own bespoke qualifications according to their field of expertise.

Fire Compartmentation is essential to the design of any building, especially those of residency and multiple occupancy.  A compartment is simply a part of a building bounded by walls, floors and doors that will resist the passage of fire for a specified period of time. The fire resistance of this construction is such that, normally, a fire will burn itself out before spreading to other parts of the building or allow sufficient time for the rescue services to evacuate people from the building. Larger spaces are divided into smaller, manageable spaces and create a safe, protected space / evacuation routes, should a fire occur. 

Things to consider

  • Escape Routes              
  • Doors (including hatches to cupboards, ducts and vertical riser shafts linking floors), lift shafts and stair wells
  • Walls, floors, ceilings and loft spaces
  • Cavity barriers, fire stopping and dampers
  • PEEPS (Personal Emergency Evacuation Plan) Occupancy/residency
  • Building Use and Risk loading

Fire Compartmentation Survey

Fire Compartmentation Surveys include:

  • An assessment of the properties’ compartmentation strategy and any evacuation plans that may be applicable.
  • A comprehensive visual inspection of the existing fire compartmentation provisions which includes floors, walls, roof voids, basements, floor and ceiling voids, risers and shafts where present. Access must be gained to all these areas to ensure a complete and holistic opinion can be drawn.
  • An assessment of the condition of compartmentation and subsequent defects in accordance with relevant British Standards, Approved Document B of the Building Regulations and any site-specific fire strategy information made available.
  • A detailed review of fire doors on the premises (in some instances this may also be required as a separate inspection), particularly in care home or hotel type properties
  • Assess Service Penetrations – checking resistance of the compartment, including doors or electrical and mechanical services are within regulations.
  • Recommend and specify Fire Stopping Products and Systems.
  • A clear action plan which outlines locations of defects, photographic evidence and suggested remedial actions to be taken. To include prioritisation in a RAG (red, amber, green) format.
  • Marking up of existing floor plans (if made available) to indicate the locations of compartment walls and floors, and develop evacuation plans where required.
