Comparison of the Effects of Different Fire Test Regimes on Passive Fire Protection Materials

In the past, HSE’s Health and Safety Laboratory (HSL) has studied the performance of a variety of passive fire protection (PFP) materials in protecting a part-filled LPG tank subjected to hydrocarbon pool fire engulfment. However, this is only one potential fire incident scenario that can threaten a process vessel; another is a jet fire, perhaps resulting from an ignited release from a leaking ...

Theoretical and experimental analysis of the heat absorbing profile in passive fire protection materials

Substances undergoing endothermic reactions are of wide interest in the development of materials oriented to fire passive protection. These components can be used as aggregates in usual building materials in order to improve the response under high temperature scenarios. The mechanism of action is based on the absorption of part of the generated heat of combustion by the corresponding endotherm...

Microcontroller Based Fire Protection System

Realization of microcontroller based real time fire protection system is considered and described in the paper. Given solution is based on application of microcontroller AT89S8253. The system is consisted of set of sensors connected to control device (microcontroller module). Control, monitoring and diagnostic are performed via computer of PC type serially connected with control device. Charact...

SIL Rating Fire Protection Equipment

SIL's (Safety Integrity Levels) are used by IEC 61508:1998 [1] to characterise the required functional safety of computer control systems. For example, SIL 4, the highest rating is for fly by wire aircraft and weapons systems and track circuited train signalling systems while SIL 2 is typical of certain Programmable Logic Controllers (PLC). Fire control panels have not been SIL rated to date ev...
