At 11:25 a.m., Wailuku firefighters met with company representatives and learned that anhydrous ammonia gas was leaking from a room that housed the storage tanks.

Employees had already evacuated the building when fire crews arrived.

Nearby business’ that called in to report smelling the strong irritant were advised to shelter-in-place by closing all windows and to remain indoors until the leak was fixed. No extended evacuations were ordered and Lower Main Street remained open.

Two people were evaluated by paramedics for headaches and nausea but were released at the scene.

Fire crews gave the all-clear after air quality readings were back to normal levels at around 12 noon.

Anhydrous ammonia is commonly used as a refrigerant in large commercial refrigeration applications and is easily detectable by its strong pungent odor.

Maui Soda & Ice Works General Manager Cathy Nobriga Kim released the following statement on Wednesday morning:

“The release of anhydrous ammonia that took place at our Wailuku plant yesterday morning (Tuesday, July 19, 2016) was the result of safety precautions built into our refrigeration system. Three to five pounds of the material was released into the atmosphere after less than optimum temperature conditions were recorded in the room where the substance is stored.

The Maui Fire Department Hazmat Crew was on scene as a safety precaution to further ensure our employees safety before they returned into the building.

Everyone at Maui Soda & Ice Works is sincerely thankful for the assistance of the Maui County Fire Department and grateful that no one either within or outside of our company was injured.”
