Cal/OSHA Issues Alert on Ammonia Safety at Wineries

The alert cites a September 2012 fatality that is under investigation.

A recent hazard alert posted by California's Division of Occupational Safety and Health, better known as Cal/OSHA, reminds workers and managers at the state's wineries about the dangers of anhydrous ammonia, which is used under pressure as a liquefied refrigerant. A worker died in September 2012 in an incident involving it, and the alert says the incident is still under investigation to find the root causes.

The document describes NH3 as a corrosive to the skin, eyes, and lungs, even at low concentrations in air. Exposure to 300 ppm is immediately dangerous to life and health.
