Event description

EMPLOYEE KILLED AFTER BREATHING NITROGEN IN RESPIRATOR

Investigation abstract

Digital Equipment Corporation had established a central breathing-air station to supply air line respirators in three plant locations. An outside contractor was connecting a fourth location to the existing system using a nitrogen gas purge while braising copper line. Employees at one of the existing air line locations were not notified of the work going on. As a result, Employee #1 plugged in his respirator and was killed when he breathed nearly pure nitrogen.
