Valve fails while being turned and releases 200 pounds of NH3 leading to 1st and 2nd degree burns

On October 4, 2005, Employee #1 was working as a refrigeration mechanic. An ammonia system valve in freezer Number 7 was being turned, when the bonnet came loose with the wheel, releasing approximately 100 to 200 lbs of ammonia. Employee #1 was 35 feet up without fall protection, and he had to slide down racking to escape. He gave notification to shut the system down and summoned the city’s hazard materials team. The plant and the surrounding businesses were evacuated without incident. Employee #1 sustained first and second-degree chemical burns on his left hand. He was not hospitalized. This was not the first time that the bonnet of that Hansen 1.25 in. shut off valve had come off when the valve was turned. This type of valve is now made with a bolt to prevent the bonnet from turning.
