There are various hazards associated with work in confined spaces and these regulations were constructed to ensure that identifiable risks are suitably assessed and adequate control measures and emergency rescue arrangements are in place. The legislation defines a confined space as:
"any place, including any chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or other similar space in which, by virtue of its enclosed nature, there arises a reasonably foreseeable specified risk”
– Regulation 1: Citation, commencement and interpretation
It goes on to describe the specified risks that must be managed for compliance. Each risk can cause serious injury, loss of consciousness and/or asphyxiation or drowning to any person at work within a confined space; they are:
Employers must ensure that work in confined spaces carried out by employees (and their self) is done in a manner so it complies with the requirements outlined within the regulations. Self-employed individuals must similarly ensure that their own work is carried out in line with the regulations.
Additionally, employers and the self-employed have a duty for compliance in respect to matters that are within their control when work in confined spaces is being carried out by other workers (who are not their employees).
The potential for danger while working in a confined space must be re-assessed if it’s possible that the site has been affected by a change in weather conditions, temperature or other activities occurring nearby.
