Title Frozen Food Company in California Fined for Toxic Gas Release in San Jose
Introduction LA Testing provides industrial hygiene and environmental testing services to identify exposure risks to ammonia and other chemicals to protect workers, the public, and to help keep companies in regulatory compliance.

Huntington Beach, California, January 31, 2023

Last month, the County of Santa Clara’s Office of the District Attorney announced that a food manufacturer with a facility in San Jose was convicted and sentenced for a large release of toxic ammonia back in 2021. The company had been criminally charged with negligently discharging an air contaminant, failing to immediately report that release, providing inadequate training to its contractors, and failing to implement an adequate emergency action plan according to a news release from the district attorney’s office.

The anhydrous ammonia was used as a refrigerant and it was reported that approximately 3,400 pounds of it escaped from the plant into the surrounding community, forcing residents to shelter in place. The company was ordered to pay close to $85,000 and is upgrading systems and procedures to prevent future releases.

Ammonia is a chemical compound that is both made by humans and naturally found in the environment. A significant amount of ammonia is produced for use as fertilizer, but it is also used as an industrial refrigerant and to manufacture synthetic fibers, plastics, explosives and other materials. According to the U.S. Environmental Protection Agency (EPA), each year, there are about 150 accidents at facilities that make, use or store extremely hazardous substances such as ammonia refrigeration facilities.

“Exposure to ammonia typically occurs through inhalation or skin contact,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “Contact with it can cause serious injuries and even fatalities at high concentrations. Exposure to even low levels may cause concern for some people with asthma and other health conditions. To help prevent exposure risks and to support health and safety programs at facilities that utilize ammonia, LA Testing offers industrial hygiene and environmental laboratory testing services and sampling supplies to detect it and many other industrial chemicals.”

Several years ago, LA Testing sponsored an educational video about ammonia and exposure risks that can still be seen at:
