Loss of Containment Incident Analysis
This report presents findings from a project conducted by the Health and Safety Laboratory (HSL) on behalf of the Health and Safety Executive (HSE). The research was funded by the HSE Hazardous Installations Directorate (HID). The overall aim of the project was to provide information on incidents that involved a loss of containment in order to inform HID regarding intervention strategies.
Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR), employers and the self-employed are required to report certain work-related diseases, accidents and dangerous occurrences to the Health and Safety Executive (HSE). Dangerous Occurrences include incidents leading to a loss of containment. In the chemical and petrochemical industries the loss of containment of a hazardous substance has been the main factor in a number of major incidents.
A sample of 718 investigations into loss of containment incidents were identified from approximately 2,500 investigations, provided by HSE of accidents, incident and dangerous occurrences, subject to their containing enough detail to produce a profile of the occurrence. The sample was selected from across an 11 year time period, from 1991 to 2002. The advantage of sampling over a wide time period is that the incident profile that is developed should be more representative.
