This course explains how to determine the correct quantity and location of fire and gas detectors to appropriately reduce risk to a tolerable level.
Fire and gas detection and suppression system design techniques currently in use are often considered unsatisfactory due to their rule-of-thumb and experience-oriented nature, without any real means to quantify risk.
Only after technical report ISA-TR84.00.07-2018, Guidance on the Evaluation of Fire, Combustible Gas, and Toxic Gas System Effectiveness was published, was a comprehensive framework for performance-based fire and gas design established.
This certificate course describes the techniques recommended in the technical report, along with the hands-on application of these techniques and their associated software tools. It applies to a wide range of professionals involved with fire and gas systems—from high-level decision-makers to hands-on users.
It teaches a basic understanding of design techniques and includes a comprehensive case study that involves employing software to develop a complete performance-based design for a sample oil and gas production facility.
