Fire Compartmentation

Ventro provides a full range of fire safety services, ensuring a cohesive approach to fire safety within your building. Our multi-skilled teams guarantee that no fire safety stone is left unturned, leaving our clients with complete peace of mind.

Fire Compartmentation is the strategy required to prevent the spread of fire by subdividing buildings into a number of compartments.

Approved Document B, Volume 2 defines a fire compartment as “A building or part of a building comprising one or more rooms, spaces or storeys constructed to prevent the spread of fire to or from another part of the same building or an adjoining building”.
The spread of a fire is prevented using fire-resistant walls, floors and special measures that cope with openings in compartment lines such as doors, penetrations, and ductwork and usually offer between 30-120 minutes of resistance. Compartmentation provides occupants with additional time to evacuate by preventing escape routes becoming compromised by the spread of fire and smoke. Compartmentation in the case of a fire within a block of flats whereby each flat is its own compartment means that a full building evacuation is not always necessary, and a stay put policy may be enforced. In the case of a hospital fire where moving occupants vertically to different floors can be challenging, compartmentation means that residents may be moved horizontally to compartments on the same floor away from the fire.

What does HTM 05-02 say about Compartmentation?

However, these compartments should be divided into sub-compartments in the following circumstances:
Where a patient access area exceeds 750m² (1000m² in Outpatient Areas)
Where an area contains than sleeping accommodation for more than 30 patients
Where it contains areas to which more than 30 patients have access at the same time

Our Approach

Ventro’s unique approach adopts a 3-step cycle to establish that our clients are proactively tackling fire-safety by ensuring buildings are not only brought up to compliance but kept that way. The 3-Step Approach includes our detailed 5-yearly Healthchecks, Remedial and Installation Planned Programmes of Works, and ongoing Regulatory Routine Maintenance Contracts.


The Healthcheck is an extended survey of the buildings to diagnose the issues within a building. We recommend that a Healthcheck is carried out at the beginning of engagement with ourselves and subsequently re-visited every 5-years as an extended review of the building in conjunction with our maintenance contract; to ensure our clients are keeping ahead of the curve with the most up-to-date solutions in an ever-changing regulatory environment.


Ventro provides an end-to-end project management service for all fire safety and regeneration projects, including the project, technical, site, and resident liaison aspects, ensuring that any remedial works required are carried out seamlessly and in a hassle-free manner for the client. Inclusive of specification, design, waste removal, supply and installation to provide the full turn-key solution to your project.


Following diagnosis and remediation, it is key that ongoing maintenance of all fire safety systems is proactively and routinely kept up-to-date to guarantee compliance requirements are met and ensure the safety of building users and longevity of installations. These are complemented every 5 years by an extended Healthcheck as described above to ensure total peace of mind.
