The fire suppression system at BJ’s gas station in Riverhead was accidentally activated this morning, coating customers, vehicles and much of the site with a dry chemical agent that’s used to extinguish fuel-related and electrical fires.

Two people were transported to Peconic Bay Medical Center for evaluation after inhaling the powder. There were no serious injuries, Riverhead Volunteer Ambulance Corps President Garrett Lake said.

The agents are considered non-toxic to humans and the environment, but can cause temporary respiratory irritation, or skin and eye irritation upon exposure.

The system was undergoing routine maintenance at the time of the accidental discharge, Riverhead Police Chief Ed Frost said. Customers were fueling eight vehicles at the station when the incident occurred, he said.

The incident took place shortly after 11 a.m. Riverhead Police, fire department and ambulance responded to the scene. The Southampton Fire Marshal’s Office, covering for Riverhead fire marshal’s office, responded to investigate.

Lake said the discharge took place while the fire suppression system was being tested.

Fire suppression systems at gas stations are typically installed in the overhead canopies and use agents like sodium bicarbonate or mono-ammonium phosphate to quickly smother and extinguish flames to minimize the risk of explosion. The systems are required by law and must be inspected and tested regularly according to national fire protection standards.
