Struck by falling object

A crew of 5 workers were installing an 8'x10' process door when the lifting lug on the door became detached. This resulted in the door free falling approximately 22"" to the ground and ultimately falling over onto one of the crew members.

Inhalation of radiations, caustics, toxic and noxious substances

A Chemicals I&E Technician was sprayed in the face with a liquid assumed to contain condensated hydrogen fluoride. The miner was in the process of performing routine preventative maintenance on an instrument tap. The system that the miner was working on is expected to be under a vacuum under normal conditions. The injuries suffered by the EE resulted in his death.
