The risk assessment for entry to a confined space is a legal requirement and could save lives if done properly.
Confirm Whether the Space Qualifies
This does not mean that all enclosed spaces are confined spaces. The legal definition of a confined space is a space which is substantially enclosed and where there may be a foreseeable serious risk. This could be a tank, silo, sewer, basement, etc. and includes deep excavations.
Identify the Specific Hazards
Make a list of specific hazards present within the space, such as toxic or oxygen deficient atmosphere, risk of engulfment, presence of moving parts or extremely high temperatures. Make sure the list is specific to the confined space under review and does not include generic hazards found in other confined spaces.
Decide Who May Enter and When
Detail who is authorized to enter the space and the circumstances under which they will enter the space, and who will be supervising them. For Confined Space Rescue, see https://www.agofirerescue.com/confined-space-rescue/.
Specify the Rescue Method Beforehand
Match Equipment to the Hazards
This must also cover the selection of the appropriate equipment for the space to be entered for example the type of atmospheric monitor, breathing apparatus and PPE to counteract the specific space hazards identified.
Set a Review Schedule
Review the assessment at any time that there are changes to the confined space, following any incident where entry has occurred and at least on an annual basis. Ensure the assessment is updated and that a record of any reviews is kept up to date and signed and dated.
A thorough pre-entry assessment is your best protection.
