SIL Rating Fire Protection Equipment
نویسندگان
چکیده
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 even though certification organisations like Factory Mutual provide SIL for various PLCs in their approvals guides. This paper addresses SIL' derivation/allocation to fire systems and fire control panels in particular.

Congested Public Goods: the Case of Fire Protection
This paper uses a fire protection measure based on a community’s tire insurance rating to estimate the strength of congestion effects for fire protectron services. The empirical results show that the congestion properties of fire protection are much like those of a pure public good. In addition, the paper introduces a new notion of returns to scale for public goods and estimates the relevant pa...
متن کاملA comparison of fire danger rating systems for use in forests
Fire danger is the resultant of ‘factors affecting the inception, spread and difficulty of control of fires and the damage they cause’ (Chandler et al. 1983). If any of these factors are absent, then there is no fire danger (Cheney and Gould 1995). Fire danger rating is ‘a fire management system that integrates the facets of selected fire danger factors into one or more qualitative or numerical...

BacKground A number of fire danger rating systems, which integrate selected quantifiable factors contributing to fire danger, have been developed to provide numerical indices relating to fire protection needs. it is important to note that fire danger indices have no real physical manifestation – they are just indices. Calculation of fire danger indices generally rely on information relating to ...
