Coroner statement: "The farm workers were going into the apple store, which is kept cool by nitrogen, to look for apples. We don't know what happened after that - I presume they were overcome by fumes and the absence of oxygen, but we can't be sure yet."
Fruit can be kept fresh through controlled atmosphere storage, which regulates temperature, oxygen, carbon dioxide and humidity. Typically, the ripening process is slowed by storing fruit in sealed rooms, where oxygen levels are reduced by the infusion of nitrogen gas.
