Fire and Gas Mapping: Practical Application (EC56)

ISA EC56 Training - Image of Safety concept of safety and security system on offshore oil and gas processing platform, hand hold gas detector for check hydrocarbon leak to protect fire and explosion

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.
