The duty of the fire protection system may be to extinguish, control, or provide exposure protection to control a fire and reduce the risk of a ripple effect. For some applications foam pourers or fixed water monitors may be a more appropriate method of delivery than sprays or sprinklers. Passive fire protection can provide an effective alternative to active systems for protecting against vessel failure. This generally consists of a coating of fire resistant insulating media applied to a vessel or steel surface.
It is often used where water or other active protection media supplies are inadequate, such as in remote locations, or where there are difficulties with handling fire water run-off. An important criterion in deciding which system is most appropriate for fire exposure protection is the likely duration of the exposure to fire as passive fire protection is only effective for short duration exposure (1-2 hours). To measure this, we test the heat transfer between cold and hot face temperatures.
Intumescent coating is an effective extinguishing foam which is sprayed against the required components and reacts in the instance of fire. A reinforcing glass fibre scrim or steel wire gauze is applied to prevent cracking and peeling of the coating under fire conditions and to provide additional strength to resist the impact of high pressure water jets. The fire protective coating is further protected by a weather protective top layer. Fibre matting systems consist of fireproof mineral fibre matting clad with a protective galvanised steel sheet. The protective capability of the system is provided by the poor heat conductivity of the system.
