DANGER: The presence of a second
operator nearby is essential to carry out a
possible evacuation.

injured person within a period of less than 15 minutes.
After that time, the operator is in danger.
Throughout the rescue phase, there must be
direct or indirect visual contact or other means of
communication between the rescuer and other
persons involved in the rescue.
For rescue operations, the use of a comfortable
harness EN 813 (type Promast™, Transport,
Emergency) or a harness equipped with an EN 1497
