Event description

Seven injured after inhaling hydrochloric acid

Investigation abstract

Employees #1 through #7 were preparing a plastic molding machine that had been r unning polyvinyl chloride (PVC) at 350 degrees F to run nylon at 500 degrees F. During the changeover, the purging step to remove PVC remaining in the molding m achine was inadvertently left out. When the hot nylon hit the PVC in the machine , hydrochloric acid was formed through the thermal decomposition of PVC.

The employees suffered injuries to their eyes, throats, and lungs and were hospitalized. Employees #1 through #7 were no t equipped with ppe.
