Health and Safety

Confined Spaces

A confined space is a place that is substantially enclosed (though not always entirely), and where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen).

Particular care must be taken when working in confined spaces likely to be unventilated (e.g. storage tanks and service ducts). In these areas there is a risk of the build up of flammable, toxic or suffocating atmospheres, with no obvious indication of the hazard. In such circumstances only specifically trained and authorised persons are permitted to enter, and the necessary required precautions must be taken before work can begin.

Entry must be carried out in accordance with a “permit to work” which formalises the precautions needed. For detailed advice please contact the Senior Engineer in the Estate Office or the Safety Office.
