Entry vs. Non-Entry
If the worker is physically able to use rescue equipment (safety retrieval line, rope, wristlets, etc.), rescuers may choose not to enter the space.
Instead, they can provide appropriate equipment and assistance necessary to bring the worker out of the space (a non-entry rescue).
In situations in which the worker is unresponsive, atmospheric hazards are extremely high, or significant time has elapsed before rescuers arrive at the site, emergency rescue personnel may decide the risks associated with entering outweigh the potential for a successful rescue. If this is the case, rescuers may elect not to go into the confined space until conditions warrant a safe entry. However, remember a rescue attempt will likely become a body retrieval after 4 minutes without oxygen.
As mentioned earlier, non-entry rescue is the preferred method for confined space emergencies when self-rescue is not possible. It's important to remember the confined space Attendant should not perform entry rescue. Rescue requiring entry should only be performed by a trained rescue team or emergency service providers.
Rescue Equipment
The importance of having the right rescue equipment on hand can't be stressed enough. Rescue equipment may include:
- full body harness with retrieval line attached
- wristlets (may be used in rescue when it can be shown that they are the safest and most effective means of rescue)
- hand-cranked mechanical winch and tripod (required when entrant is five feet or more below the entrance)
- ladder
- explosion-proof lighting
- SCBA/SAR
- stretcher
- approved head protection
