What is SIL?

SIL Fire Systems use equipment that execute Safety Instrumented Functions (SIF) under a functional safety management (FSM) structure. This safety mechanism is measured to give a SIL (Safety Integrity Level).

Although the reliability of a fire safety product is crucial in every type of environment, there are some applications which demand additional proof of reliability. These are applications such as marine, rail, hazardous areas and power stations which will lose a huge amount of revenue if the site is unable to operate or must shut areas down.

Many of these type sites require that all safety apparatus is SIL approved. This is to ensure that the safety equipment is robust and is unlikely to stop functioning. However, even the most reliable of products will break down at some stage or require maintenance. SIL assessment gives an estimated failure rate of a product, which subsequently enables applications like these to estimate downtime costs/loss of revenue over a period of time.
