On January 10, 2020, Employees #1 and #2 were working from a scissor lift and dismantling an ammonia blast freezer in preparation for installing a new freezer. As they worked, ammonia was released. Employee #1 was killed by the chemical exposure. Employee #2 self-rescued, but was seriously injured. He was transported to the hospital and treated for severe burns and inhalation injuries.

Could this be prevented by making sure to cut-off/isoltae the ammonia supply before undertaking the work ?
