Passive Fire Protection is the combination of fire resistant materials with the constructional fabric of the building to create an air-tight and sealed structure. Such as sealing any service, opening or hole penetrating a compartment wall, floor or ceiling. This prevents the spread of flame, smoke and heat throughout the building.

Buildings are split into confined zones with set resistances (in minutes i.e 30/60/90/120 minute resistance). By creating a fire resistant obstacle (wall, floor, fire stopping, fire door) it will impede the impact and spread of the flame and smoke will have on a building. These zones are referred to as Compartmentation, the most common example is the use of a riser cupboard to transport services vertically throughout a building. Risers are designed to achieve a set fire resistance depending on its fire strategy to which if a fire did occur within the fire would not leave that riser until that resistance has been met.

It is vital that in all areas of compartmentation adequate and suitable protection is afforded to any imperfections, fit or openings in the constructional fabric (e.g. holes in walls and floors). This can be via ‘Fire Stopping which is designed to fill that hole with proven fire resisting materials that will last the fire duration depending on its installation specifications and requirements.
