Your Passive Fire Protection Plan

Are you building a roadtunnel, train tunnel or metrotunnel? For every type of large-scale underground structure you design, you will need to include a passive fire protection plan to protect it against fire. A complete passive fire protection plan, consists of 4 key building blocks:

1. Fire escape route

Allow people enough time to react and evacuate

The escape route needs extra attention to guarantee a successful evacuation of all the people inside. Studies show that the actual time needed to evacuate a tunnel after a fire alarm might be longer than you would expect. This is why it is important that the escape route can resist the fire can withstand high temperatures for much longer, independently from the rest of the tunnel.

2. Compartmentation & fire stopping

Prevent the fire from spreading through the building

If a fire can be contained within a closed compartment within the building, people can safely evacuate and fire fighters can extinguish the fire. Compartmentation is therefore one of the key elements in passive fire protection. Make sure walls, ceiling and floor will withstand fire and integrate fire resistant doors and all the necessary fire stopping solutions to prevent the fire from spreading through the building.

3. Smoke extraction and ventilation ducts

Get rid of smoke and slow down the development of fire

Smoke is often the main reason why people become victim of fire. When smoke and toxic gasses fill the space, it reduces not only the visibility, but also the amount of breathable air and leads to suffocation. Smoke is also a main factor in the spreading of fire. This is why a ducting system for smoke extraction is a key factor in your protection design.

4. Structural protection

Avoid the collapse of the loadbearing structure of the building

Once a building is on fire, the loadbearing structure can deteriorate and collapse. Structural protection safeguards the loadbearing structures (steel, concrete, timber, composite or others) in such a way that they will withstand high temperatures and maintain their load bearing capabilities. When a building is saved during a fire and is fit for repair and re-use, it is due to an efficient and well tested structural protection solution.
