What is the Main Objective of Fire Compartmentation?

One of the biggest risks in a fire is the spread of smoke and toxic gases. If not handled correctly, any attempt to evacuate a building will be hindered by the spread of smoke. Therefore, it is integral that there are structural measures in place to contain smoke and fire.

Airflow between doors and rooms can push flames and smoke throughout a building. This is called the ‘chimney effect’. Compartmentation aims to mitigate this effect, controlling the spread for a prescribed period of time. This length of time can range between thirty minutes and four hours. The building’s ‘compartments’ will be protected using fire walls, doors, and cavity barriers. This then limits the fire to a specific part of the building. This helps firefighters manage risk more effectively, as well as protecting primary escape routes. Compartmentation also provides fire separation for adjoining buildings.

For compartmentation to be successful, all potential sources of airflow must be protected using fire-resistant materials. This includes joints and rafters, pipes, air ducts, and ceiling voids. Compartment walls and floors should also be installed for parts of buildings that serve separate purposes. For instance, offices for different companies as part of a business complex.

Compartment solutions must be reviewed regularly in case of any inadvertent breaches. These breaches can be found in cavity barriers, joint seals, and penetration seals. Regardless of size, any breach in a compartment will render it ineffective against the chimney effect.

Often, third party contractors such as plumbers or electricians can unknowingly compromise fire compartments. CLM Fireproofing will conduct thorough inspections of fire compartments, swiftly identifying and rectifying any breaches.
