The dust is irritating to the nose and throat. Inhalation of high concentrations causes bronchospasm, respiratory distress and wheezing. Very high concentrations can cause pulmonary edema and even death if inhaled. It is irritating to the eyes and skin. Oral burns to the digestive tract.
A serious hazard to the environment.
This product is combustible and highly irritating.
First aid measures
Remove contaminated clothing and rinse with plenty of running water.
Lift the eyelids and rinse with running water or saline. Seek medical attention.
Remove from scene quickly to fresh air. Keep airway clear. If breathing is difficult, administer oxygen. If breathing stops, resuscitate immediately. Seek medical attention.
Gargle with water and give milk or egg whites. Seek medical attention.
Strong oxidizer. Contact with flammable and organic materials can ignite easily. Reacts with nitrogen-containing compounds (such as ammonia, urea, etc.) to form explosive nitrogen trichloride. When heated or damp, it can easily produce highly toxic fumes.
Hazardous combustion products:.
Carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen chloride, sodium oxide.
Fire extinguishing method:
Firefighters must wear full body fire and hazmat suits and extinguish the fire upwind. Whenever possible, move the container from the scene of the fire to an open area while extinguishing the fire. Then select the appropriate fire extinguishing agent according to the cause of the fire.
Spill Emergency Response
Isolate the spill contaminated area and restrict access. It is recommended that emergency responders wear dust masks and general operating uniforms. Do not come into direct contact with spilled material. Small spills: Cover with dry sand, vermiculite, or other inert material. Collect in a closed container with a clean shovel. Large spills: collect for recycling or take to a waste disposal site.
Handling Disposal and Storage
Precautions for Operation
Airtight operation, providing adequate local exhaust air. Prevent the release of dust into the workshop air. Operators must be specially trained to strictly follow operating procedures. It is recommended that operators wear dust masks (full face masks), one-piece mylar hazmat suits, and rubber gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Avoid generating dust. Avoid contact with ammonium salts, nitrides, oxidizers and alkalis. Equip fire-fighting equipment and spill response equipment of appropriate variety and quantity. Emptying the container may leave harmful residues.
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Package must be sealed and not exposed to moisture. It should be stored separately from flammable (combustible) materials, ammonium salts, nitrides, oxidizers, alkalis, etc. Do not mix them. Suitable materials should be available in the storage area to contain spills.
Exposure Control/Individual Protection
Tightly sealed to provide adequate local exhaust ventilation.
A dust mask (full face mask) must be worn when there is a possibility of exposure to dust. An air respirator should be worn in emergency situations for rescue or evacuation.
Protected in respiratory protection.
Wear a hooded mylar hazmat suit.
Wear rubber gloves.
Smoking, eating and drinking are not allowed on the job site. Shower and change clothes after work. Maintain good hygiene habits.
