In April 2011, an OSHA State Plan investigated a 3,600-pound ammonia release at a large warehouse where anhydrous ammonia is used in the refrigeration system in a cold storage building. In this incident, one worker was burned on the arm from the escaping gaseous ammonia. As part of the planned mechanical integrity schedule, two (2) employees…...
Employees #1 and #2 were draining refrigerant oil from anhydrous ammonia refrigeration system oil traps in fruit cold storage warehouse(s).
