① Quickly evacuate the personnel from the leaked contaminated area to the upper wind, and isolate them until the gas has been exhausted. It is recommended that emergency handlers wear self-contained positive-pressure respirators and chemical protective clothing (complete isolation) specially recommended by the manufacturer.
② Cut off the air supply. Spray ammonia water or other dilute lye to neutralize, pay attention to collecting and treating wastewater. Then exhaust (indoor) or strong ventilation (outdoor). If possible, use the exhaust fan to send the residual or leaked air to the washing tower or the fume hood connected to the tower.
