Leak / gas detection - HSE

General PrinciplesContributory Factors For An Assessor to Consider Concerning Leak/Gas DetectionMajor HazardsGuidance and Codes of Practice Relating to Leak/Gas DetectionFurther Reading MaterialCase Studies Illustrating The Importance of Leak / Gas DetectionThe following aspects should be considered with respect to Leak/Gas Detection: 1. Human Factors; 2. Objectives of leak/gas detection systems; 3. Types of leak/gas detectors required; 4. Maintenance of leak/gas detectors; and 5. Management of leak/gas detector systems. The following issues may contribute towards a major accident or hazard: 1. Unrecognised high-risk areas, where detectors could be used; 2. No detectors or the wrong types in place in high risk areas; 3. Detectors incorrectly positioned and installed on site; 4. Poor level of maintenance and control of detection systems; 5.
