Proof Testing for Safety Instrumented Systems…what you need to know!

Date From: 12 July 2018
Description: A one hour webinar from the IChemE Process Management & Control Special Interest Group around the topic of Proof Testing.
Event Type: Webinar
Venue: Online

Time: 9:00-10:00 BST
Organiser: Process Management & Control Special Interest Group

Book Event

Proof Testing of a Safety Instrumented System (SIS) is essential if the Target Risk is to be achieved and maintained throughout the life of the plant.  Failure to carry out Proof Tests at the prescribed frequencies will reduce the risk reduction achieved by the Safety Instrumented Function (SIF) and may reduce it to an such an extent that the Tolerable Risk is not achieved. The Webinar will:

• Provide an introduction to Safety Instrumented Systems;
• Set out the principles of Proof Testing;
• Outline the importance of plant operators being involved in the decisions relating to Proof Testing;
• Consider the concept of Perfect Proof Testing and Imperfect Proof Testing;
• Set out a systematic approach for the development of Proof Test Procedures.
