This is not the first time we've been at this site. The first time was in 1995, when we were looking at this exact area and helping the ski area understand why it needs to be avoided. The hazards of this location are well-known.
If you follow the proper procedures you don't have employees inside the silo doing work activity while product is being removed. We have to look at whether proper training was provided, and whether employees know what the hazards were associated with their work.
