Passive fire protection is the primary measure integrated within the construction fabric of a building to provide inherent fire safety.
This is ensured by protecting against flame, heat and smoke to maintain the fundamental requirements of building compartmentation. Also, structural stability, fire separation and safe means of escape.
Passive fire protection measures achieve their intended purpose by raising the fire resistance of the structure to a specific level. Protecting the structure against the effects of fire, and reducing fire spread through secondary ignition (i.e. by service penetrations – see fire stopping). Also by limiting the movement of flame and smoke, and minimising the danger of fire-induced collapse or structural distortion.
Passive fire protection design, incorporating passive fire protection materials and systems, serves by fire containment to protect life, safeguard the building structure, protect assets, maintain building serviceability after fire. Thereby minimising rebuild costs, and facilitating quick business recovery and continuity.
