SIL Determination

SIL Background Information

Safety Integrity Levels (SIL) are measures of the safety of a given process or machine. To say that a process meets a specific SIL is to say that it was developed using appropriate techniques and measures to ensure that it meets the systematic failure requirements of a specific safety function at that level. Levels are ranked 1-4 and the higher the number, the safer the process.

Determining SIL in partnership with Pilz

Determining the correct SIL is necessary to achieve the correct balance between safety and productivity. A methodology for assigning SIL levels can be broken down into a number of discrete stages:

  • preparation;
  • safety function analysis and mapping;
  • identification of potential accidents;
  • accident scenario frequency estimation;
  • harm frequency estimation;
  • harm frequency summation; and
  • SIL assignment.

Experienced Pilz engineers are able to determine and calculate SIL for your machine/process and in doing so, highlight any areas which may be over-protected or may be improved upon. Pilz can also specify and design any necessary hardware and software to meet the requirements of the SIL determined by the assessment. This can ultimately save money for your company in terms of equipment costs, reduced down-time or, at the other end of the scale, injuries and their consequences.
