Confined space rescue

[1] This is a last resort option as having more personnel enter an area that has already incapacitated one or more persons places the rescuer at considerable risk.

One of the initial pieces of equipment employed in a confined space is a method of ventilation to disperse collected hazardous gases and introduce fresh air into the environment.

This may include a self contained breathing apparatus (SCBA), protective headgear and the use of explosion proof lighting (to prevent igniting any gases).

The rescuer may also wear a full body harness with an attached safety line, especially if a vertical descent is required.

[1] To assist in vertical descents, a mechanical winch and tripod may be set up over the access point, if the bottom of the confined space is more than five feet from the entrance.
