Emergency response to leakage of zirconium tetrachloride


Isolate the contaminated area and set up warning signs around it. It is recommended that emergency personnel wear gas masks and chemical protective clothing. Do not directly contact the leaked material to avoid dust. Be careful to sweep it up and prepare a 5% aqueous or acidic solution. Then gradually add dilute ammonia water until precipitation occurs, and then dispose of it. You can also rinse with a large amount of water, and dilute the washing water into the wastewater system. If there is a large amount of leakage, clean it up under the guidance of technical personnel.
