At 3:30 p.m., an employee was repairing a valve in an ammonia (NH3) refrigeration line. He was raised to the valve location in a basket attached to a forklift. He removed the actuator and was trying to close the valve manually when the valve became dislodged from the piping. The ammonia was released from the main system directly toward the employee, who died from burns and asphyxia. Two other employees working in the area, tried to rescue their colleague, were injured and taken to Hospital. Fifteen workers were treated on site by medical personnel ; neighbours complained about the smell but were –according to the firefighters- not at danger due to the wet weather. The leak was stopped at 7 pm.
