Event description
Employee asphyxiated by nitrogen in sandblasting hood
Investigation abstract
When Employee #1 could not obtain breathing air from the installed line, he adap ted unapproved hoses with quick disconnects so he could connect a respirator for use in abrasive blasting to a gas line supplying a blasting pot. This piping wa s not color coded or labeled in accordance with company policy, so Employee #1 d id not know he was connecting to a nitrogen line instead of compressed air. He d ied of asphyxia. Since nitrogen is a waste gas in an air separation plant, it is used instead of compressed air for operating pneumatic equipment.
