Explore the Importance of Fire Compartmentation in Preventing the Spread of Fire within a Building

Fire safety is crucial for any building, as uncontrolled fires can result in extensive damage, injury, and loss of life. A key aspect of fire safety is compartmentation i.e. dividing a building into compartments separated by fire-resistant walls and floors.

Key Points

• Fire compartmentation works by restricting fire in a specific area
• There are a lot of benefits of fire compartmentation
• Building owners should know the factors that ensure effective compartmentation

Effective compartmentation is vital in preventing the spread of fire from its origin to other parts of the building. This article explores the importance of fire compartmentation and how it helps contain fires.

How Does Fire Compartmentation Work?

Fire compartmentation refers to sub-dividing a building into individual fire compartments separated from each other by fire-resisting construction. These compartments act as fire containment zones and prevent or slow the spread of fire from one compartment to the next.

Compartmentation works on the principle that fires will be confined to the room or area of origin for a reasonable time, allowing people to evacuate and the fire brigade to intervene.

The walls and floors separating compartments must withstand high temperatures and prevent the passage of flames, hot gases and smoke for a specified fire resistance period. Doors between compartments are also fire-rated. In addition, cavities and concealed spaces like ducts, piping and ventilation shafts that could allow fire spread between compartments must be sealed off with fire-stopping materials.

Benefits of Fire Compartmentation

There are several crucial benefits of proper fire compartmentation

Prevents Fire Spread

Well-designed compartments contain the fire in its original location, preventing it from spreading rapidly throughout the building. This provides vital time for building evacuation.

Reduces Property Damage

By limiting the fire spread, the extent of damage to the building structure and contents is lower, reducing asset loss.

Facilitates Progressive Horizontal Evacuation

Occupants can evacuate horizontally into adjoining fire compartments that aren’t affected by the fire. This is safer than using stairs or lifts.

Allows safe firefighting

Firefighters can isolate the fire compartment, making it easier and safer to suppress the fire.

Increases Structural Stability

Fire-rated compartment walls prevent structural collapse for a longer time. This prevents injury and allows more evacuation time.

It Allows For a More Efficient Phased Evacuation

The building can be evacuated in phases – occupants in the fire compartment first, then adjacent compartments. This prevents congestion and panic.

Protects Vital Things In The Building

Critical equipment like generators and IT servers can be located in separate fire compartments to ensure operational continuity.

Factors That Contribute To Effective Compartmentation

Several factors are vital in constructing effective fire compartments.

The Euroclass System

The materials that are used in fire safety and fire prevention practices should be of a certain quality.

The Euroclass system categorises construction products based on their reaction to fire into classes A to F. Products rated A1 and A2 meet strict non-combustibility standards and do not contribute to fire in any way. B, C, D, and E classifications denote increasing levels of combustibility and contribution to fire spread from minor to high.

Following Euroclass fire safety guidelines for furniture, wall finishes, floor coverings, building insulation, and structural elements reduces risk in case of accidental fires and improves occupant safety.

Completely sealed compartments

All openings and service penetrations must be adequately protected using tested fire-stopping products to seal any gaps or cracks.

Limiting openings

The number and size of openings (doors, ducts) between compartments are kept minimum to restrict fire spread. Doors must be fire-rated and self-closing.

Structural stability of boundaries

Compartment walls must maintain structural integrity during a fire without collapse. Joints must be able to accommodate movement during a fire.

Regular Maintenance

Any damage to compartment boundaries like walls and floors must be identified and repaired. Fire doors should be regularly maintained.

Compatible Tenancy

Parts of the building with greater fire risk should be sited within separate compartments.

Proper Escape Routes

There must be alternative escape routes from compartments so that exit paths don’t get blocked by fire.

Final Words

Effective fire compartmentation is crucial in any building for safeguarding life and property. Proper design with well-constructed fire barriers, openings protected with fire-rated doors and sealing of service penetrations is vital. Compartmentation works in conjunction with other fire safety measures like detection, extinguishment and evacuation systems.

Periodic inspection and maintenance of all compartmentation measures also go a long way in averting fires and mitigating their damage. Robust compartmentation backed by fire safety management procedures ensures built-in resilience against fire spread, making buildings intrinsically fire-safe.
