Compartmentation Surveys
Building Fire Safety
Compartmentation is a critical fire safety strategy that involves dividing a building into fire-resistant sections, or “compartments,” using walls, floors and ceilings designed to resist fire and smoke for a set period (e.g., 30, 60, 120 minutes). This method slows down the spread of fire, protects escape routes and reduces damage to property. Even a small hole, like one left by an unsealed cable or pipe, can completely compromise a fire compartment, allowing smoke and toxic gases to pass through long before flames do.
WHY IS COMPARTMENTATION IMPORTANT?
Effective compartmentation isn’t just about fire-rated walls; it’s about the entire system working together. Key components include fire-rated partitions (walls and floors), properly installed and maintained fire doors, fire-stopping seals around pipes, cables and ducts that pass-through walls/floors, and intumescent products that expand under heat to block fire/smoke. Any breach in these elements, like an unsealed cable tray or a damaged fire door, can cause the whole system to fail.
COMMON SIGNS OF COMPARTMENTATION FAILURE
Some red flags often found during Passive Fire Surveys include unsealed openings around service penetrations, missing or damaged intumescent collars and wraps, fire doors that don’t close properly or are wedged open, gaps above ceiling tiles or in riser cupboards and DIY work that has compromised fire barriers. These issues may go unnoticed day to day, but they can be life-threatening in an emergency.
WHO NEEDS TO WORRY ABOUT COMPARTMENTATION?
Compartmentation is essential in a wide range of settings, including schools, universities, residential buildings, HMOs, flats, commercial and office spaces, healthcare facilities, care homes, warehouses and industrial units, where protecting lives and limiting fire spread is critical. If you’re responsible for a building, especially as a Responsible Person under the Fire Safety Order, you have a duty to ensure the compartmentation is compliant and maintained.

COMPETENT SURVEYORS
Our team of competent compartmentation surveyors possesses the necessary qualifications, skills and experience to conduct thorough and intrusive surveys. This is crucial due to the survey’s nature, which requires in-depth knowledge of building structures, materials, design, fire safety and fire-stopping methods.
COMPREHENSIVE SURVEYS
Our surveys include a visual check of fire compartments and all compartmentation lines, including seals and fire doors. We inspect fire seals in service penetrations, evaluate sealing materials for fire rating and installation and review the condition of installed fire doors. We document non-conformances with details on locations, materials, dimensions, legislation breaches, remediation paths, access requirements and repair cost estimates. An action plan with photos, notes on defects and recommendations for fixes is also provided.
ADVANTAGES OF A FIRE COMPARTMENTATION SURVEY
A fire compartmentation survey can protect your occupants and property. Effective compartmentation reduces risk by slowing fire spread and giving occupants time to escape while containing damage. It also supports safe evacuation and firefighting by containing the fire to smaller areas, allowing firefighters to tackle it more effectively.
By choosing Exit Fire Safety, you ensure that your building’s fire safety measures are up to standard, compliant with legislation and effectively protecting lives and property.
