Vending Machine Releases Phosgene

Reuters has an interesting story concerning the release of phosgene by a hospital vending machine. Phosgene, COCl₂, has been used as a chemical weapon, although it has many industrial uses too. Phosgene irritates the eyes, nose, and throat and can lead to fatal fluid accumulation in the lungs. Apparently the vending machine caught fire and had a small explosion as a result of a food service worker's interaction with it. The phosgene probably resulted from a reaction between the freon from the broken cooling system and the heat from the fire. I don't know which struck me as funnier: that a vending machine in a hospital was spewing phosgene or that the accident resulted from maintenance of the vending machine. Maybe it's just the image of the vending machine giving off a chemical agent instead of Coca-Cola (known as the 'elixir of life' to members of my household).
