Fire-fighting measures

1) Hazardous characteristics: Strong oxidizer. In contact with flammables and organic matter, it is easy to catch fire and burn. In case of ammonia, ammonium salt, urea and other nitrogen-containing compounds and water, it will generate explosive nitrogen trichloride. Decomposition by high heat produces toxic and corrosive fumes.

2) Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen chloride.

3) Fire extinguishing method: Firefighters must wear full-body fireproof and anti-virus clothing, and put out the fire in the upwind direction. When extinguishing the fire, move the container from the fire scene to an open place as much as possible. Then select the appropriate fire extinguishing agent to extinguish the fire according to the cause of the fire.

Emergency treatment for leakage

1) Emergency treatment: Isolate the leaked contaminated area and restrict access. It is recommended that emergency personnel wear dust masks and general working overalls. Do not come into direct contact with spilled material.

2) A small amount of leakage: Avoid raising dust, collect it with a clean shovel in a dry, clean container with a cover.

3) Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.

Handling and storage

1) Precautions for operation: Airtight operation, provide sufficient local exhaust. Prevent dust from being released into the workshop air. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that the operator wear a dust mask (full face mask), a one-piece tape protective clothing, and rubber gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Avoid generating dust. Avoid contact with reducing agents and alkalis. Take particular care to avoid contact with water. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

2) Precautions for storage: Store in a cool, dry, well-ventilated warehouse, away from moisture, water, rain, fire, and isolated from fire and heat sources. It is forbidden to mix with flammable, explosive, spontaneous combustion and self-explosive substances, and it cannot be mixed with oxidants. , reducing agent, easy to be chlorinated and oxidized, and it is absolutely forbidden to mix and mix with liquid ammonia, ammonia water, ammonium bicarbonate, ammonium sulfate, ammonium chloride urea and other inorganic salts and organic substances containing ammonia, ammonium, and amine, otherwise It is easy to explode or burn, and it should not be in contact with non-ionic surfactants, otherwise it is easy to burn. Storage areas should be equipped with suitable materials to contain spills.

Exposure Control/Personal Protection

1) Engineering control: Strictly sealed, provide sufficient local exhaust.

2) Respiratory system protection: When you may be exposed to its dust, you must wear a dust mask (full face mask). When emergency rescue or evacuation, air respirators should be worn.

3) Eye protection: Protected in respiratory protection.

4) Body protection: Wear one-piece adhesive tape anti-virus clothing.

5) Hand Protection: Wear rubber gloves.

6) Other protection: Smoking, eating and drinking are prohibited at the work site. After work, take a shower. Practice good hygiene.
