Confined Space Risk Management — Study on the Use of Permanent Collective Protection Measures


Work in confined spaces involves a high level of risk. At present, employers manage this risk mainly by issuing entry permits, measuring gas levels, and requiring the use of personal protection equipment. However, in a previous study entitled “Development of a Confined Space Risk Analysis and Work Categorization Tool”, the authors noted major shortcomings in the application of these measures. Employers invest relatively little effort in measures focused on design and collective protection.

The aim of this project is to produce a critical overview of collective protection measures and to study their applicability in the workplace using real-life situations. The principles examined include doing away with confined spaces, reducing hazards at the design stage, and eliminating the need for entry.

The results will be useful in the design and modification of confined spaces and as a source of information for regulatory and standards organizations as well as for OHS professionals.
