Point -Counter Point PSM Discussion.  Below is my position and counter to "my opinion" is that of a friend who specializes in PSM for the refrigeration industry.  You can read his position at his website taocomplaince.com

Scenario:  You have a freezer with racking. The racking inside this freezer needs to be replaced. You hire a contractor to do the job. You evaluate and train the contractor as a PSM Contractor. In the midst of removing the racking, the contractor strikes some NH3 piping above the racking with a forklift and causes an ammonia release. NOTE: the piping in this scenario is 18" above the rack and against the wall and ceiling, but not protected in anyway. The driver of the forklift was trained for the forklift he was operating. The racks were used to store products that were handled by hand - not by forklift, so the forklift being used to remove the racks is only in the freezer to remove the existing racking and install the new racking.
