Accompanied descent rescue with the I'D
In case of a work emergency, a rapid evacuation solution for a single victim is an accompanied descent done by a co-worker.
- Read the technical notice before viewing the following techniques.
- It is important to fully understand the information provided in the technical notice before using this complementary information
- Mastering these techniques requires training.
- Consult a professional before attempting to perform these techniques on your own.
The I'D S can be used to control a 2-person descent, up to a maximum load of 200 kg.
For improved control, the rope must pass through a braking carabiner.
Above 200 kg, tests have shown that descent control becomes very difficult, and unforgiving of any operator error or incident during the operation.
- In the context of practicing a short descent on a dry rope, descent control is manageable.
- For a longer descent, on a wet or dirty rope, with the stress of a real victim, the risk of losing control of the descent is significant.
Consequently, if the workers at a job site weight more than 100 kg, the rescue plan should not include evacuation by accompanied descent with the I'D.
Another rescue strategy should be developed, for example installing the ropes on releasable anchors.
