We were on a long line job up in the mountains spinning fiber wrap job on a 220 skyline when one of our crew members went down in the LZ. I was running a big crew made up of guys from our crew, volunteers from other crews, and Telecom hands. I was out on a tower when I received a call from the pilot that he needed to come get me because we had a situation in the LZ. When I arrived in the LZ crew members were attending to the affected person but weren’t completely sure what the issue was. in that moment, I needed to take a step back and detach and look at the big picture. We were in a remote area, I had crew members out on towers, where the helicopter was the only means of transportation in and out of the area, and I had a crew member that needed immediate medical attention. The pilot wanted to load this crewmember into our bird and fly them to the hospital, but I was not convinced that was a good call while having guys out on towers and that bird being our only mode to get them back to the LZ. So we initiated EMS 911, I had our bird clear the LZ so that the EMS bird could land and treat our crew member. Once our crew member was attended to and evacuated from the site I sent our bird out to retrieve the crew members off the towers and bring them all back to the LZ. I had a short amount of time to make a lot of little decisions that could positively or negatively affect multiple people. In the heat of the moment, my training kicked in and enabled me to make the best possible decisions which led to the best possible outcome. Once our crewmember was evacuated to get the treatment they needed, and all remaining crew members returned to the LZ I had a major adrenaline dump and needed a few minutes to collect myself.
