Get help. Call or assign someone to call the local emergency medical service
(EMS) or fire department.
Observe all measures of safety. If at all possible, there must be another
worker present to help with the rescue before a rescuer enters a manhole. If no other
worker is available, proceed with the rescue only in cases where asphyxiation or gas
poisoning can be definitely ruled out. If atmospheric hazards cannot be ruled out by
atmospheric monitoring, do not assume the manhole is safe for entry. If in doubt, obtain
help by contacting the local rescue team (normally the installation fire department),
before starting the rescue. Organizational rescue teams can be used only if rescue
personnel are trained on all required equipment to include appropriate PPE, including
respiratory protection equipment necessary for entry into confined spaces, and with
rescue and retrieval equipment suitable for the type of confined space involved.
There are different ways in which a rescue can be accomplished. Two
methods are described here, commonly described as the Windlass System (One-
Worker) Rescue and the Two-Worker Manual Rescue.
Either rescue method uses a rescue rope. The rescue rope must be wrapped
twice around the body under the arms of the victim. Tie the rope with a bowline at the
back of the body for the Two-Worker Manual Rescue (shown in Figure 14-6) or at the
front of the body for the Windlass System (One-Worker) Rescue.
