Every member of the team is essential to the effective operation of The rescue mission. If one member is put out of action due to an injury, the entire mission may be threatened. In the course of becoming a victim, a rescuer may take with him vital equipment resources as well. The loss of a rope, harness, or other specialized equipment could jeopardize or further delay the rescue. That can smash and cut ropes, hit rescuers, victims, onlookers below, most falling objects are started on their way by some person pushing, pulling, or kicking.
Unattended feet are the more common culprits.
Adrenaline provides a quick burst of energy that can mask the normal warnings the body gives us as total exhaustion approaches. In high angle work, the rush to get into position, hauling equipment, getting to the scene, can use up so much individual energy that the team will have little in reserve for the rescue itself. A rescuer may be going over the edge with barely enough energy left to reach the victim. If unforeseen problems arise, the rescuer too often becomes an additional victim. Be aware of your energy reserves.
