SIL Notes Objective : SIL assignment establishes the risk reduction needed for each                     process system to protect against one or more hazards,                      The risk reduction is calculated as the gap between the existing risk posed by the                          process or  equipment and the risk target.                     Risk reduction (Layer of Protection) is provided by process and mechanical                                  integrity, Independent Protection Layers (IPLs) and required Safety Instrumented                      Systems (SIS). Scope :  The SIL level of each...
