Zirconium tetrachloride is a white, shiny crystal or powder that is prone to deliquescence. Commonly used in the production of metal zirconium, pigments, textile waterproofing agents, leather tanning agents, etc., it has certain hazards. Below, let me introduce the emergency response methods of zirconium tetrachloride to you.
Health hazards
Zirconium tetrachloride can cause respiratory irritation after inhalation. Intense irritation to the eyes. Direct contact with liquid on the skin can cause strong irritation and can cause burns. Oral administration may cause burning sensation in the mouth and throat, nausea, vomiting, watery stools, bloody stools, collapse, and convulsions.
Chronic effects: Causes skin granuloma on the right side. Mild irritation to the respiratory tract.
Hazardous characteristics: When subjected to heat or water, it decomposes and releases heat, releasing toxic and corrosive smoke.
So what should we do with it?
Emergency response for leaks
Isolate the leakage contaminated area, set up warning signs around it, and suggest emergency treatment personnel to wear gas mask and chemical protective clothing. Do not come into direct contact with the leaked material, avoid dust, carefully sweep it up, prepare a solution of about 5% water or acid, gradually add dilute ammonia water until precipitation occurs, and then discard 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, remove it under the guidance of technical personnel. Waste disposal method: Mix the waste with sodium bicarbonate, spray with ammonia water, and add crushed ice. After the reaction stops, rinse with water into the sewer.
Protective measures
Respiratory protection: When exposed to dust, a gas mask should be worn. Wear a self-contained breathing apparatus when necessary.
Eye protection: Wear chemical safety goggles.
Protective clothing: Wear work clothes (made of anti-corrosion materials).
Hand protection: Wear rubber gloves.
Other: After work, take a shower and change clothes. Store clothes contaminated with toxins separately and reuse them after washing. Maintain good hygiene habits.
The third point is first aid measures
Skin contact: Immediately rinse with water for at least 15 minutes. If there is a burn, seek medical treatment.
Eye contact: Immediately lift the eyelids and rinse with flowing water or physiological saline for at least 15 minutes.
Inhalation: Quickly remove from the scene to a place with fresh air. Maintain unobstructed respiratory tract. Perform artificial respiration if necessary. Seek medical attention.
Ingestion: When the patient is awake, immediately rinse their mouth and drink milk or egg white. Seek medical attention.
Fire extinguishing method: foam, carbon dioxide, sand, dry powder.
