Confined Space and Rescue
APPLIES TO
The confined space work situation is very different from any other. All confined spaces have a restricted means of entry and exit, and may have only one opening.
The entry and exit opening, and interior work area, are large enough for an employee to enter and perform required tasks.
In the UK, 'Confined Space Regulations 1997' states that "Confined Space means any place including any chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or similar space in which, by virtue of its enclosed nature there arises a reasonably foreseeable specified risk".
Confined spaces must NOT be entered without full recognition of possible dangers, proper safety training and protective equipment necessary to ensure a users safety.
Note - Tripods, Quadpods, Monopods and Davits can be regarded as anchorage's to which can be attached combinations of Fall Arrest and Recovery Devices and Material Winches. As a general rule, when making your choice you have two options:
- If the primary means of entry to a confined space is by ladders or steps it is acceptable for an operative to be connected to a Fall Arrest and Recovery Device. In the event of a fall or incapacitation he can then be raised or lowered. Note - this 'system' must not be used for man riding i.e. raising or lowering in suspension unless it is a rescue situation.
- If the only means of entry into a confined space is by 'man riding' an operative must be raised and lowered by a materials winch whilst at the same time being attached to a fall arrest and recovery device as an additional backup. This arrangement ensures that whilst in 'suspension' an operative is always protected by two seperate systems.
Having decided upon the systems required you must then determine the length of cable and type of harness required.
