There is a tremendous amount of tower modifications going on all over the country in order to bring aging towers up to loading standards for all of the carrier upgrades. Many of the modifications require removal and replacement of tower members. This can be very dangerous if short cuts are taken or conditions such as wind are not right. Recently there was a tragic accident in West VA where the crew was replacing tower members and the tower collapsed. As a safety topic for everyone I would like to know the situations involved. Was there more than one member removed when the collapse happened? Were the winds too high? Was temporary bracing being utilized? What happened? I am not point fingers or trying to lay blame I would like to know so that we can try and protect all of the workers out there installing mods as we speak. My heart goes out to all of the families involved and I hope that at the least the industry can learn how to prevent something terrible like this happening again. Any discussion or information would be greatly appreciated.
