Hazard category:
Invasion route:
Health hazards: Irritating to eyes, upper respiratory tract and skin. Inhalation can cause cough, chest pain, etc. Oral administration is harmful to health.
Environmental hazards:
Explosion hazard: this product is flammable and irritating when wet.
Part IV: First-aid measures back to the directory
Skin contact: take off contaminated clothes and rinse skin thoroughly with soapy water and clean water.
Eye contact: Lift eyelids and rinse with running water or normal saline. See a doctor.
Inhalation: leave the scene quickly and go to a place with fresh air. Keep the respiratory tract unobstructed. If you have difficulty breathing, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor.
Intake: Drink enough warm water to induce vomiting. See a doctor.
Part V: Traceability catalogue of fire control measures.
Hazard characteristics: flammable, it produces intense white light and emits high heat when burning. When it meets water or moisture, it reacts violently to release hydrogen, releasing a lot of heat, causing combustion or explosion. If it reacts violently with chlorine, bromine, iodine, sulfur, phosphorus, arsenic and oxidant, it is in danger of burning and explosion. Powder and air can form an explosive mixture. When it reaches a certain concentration, it will explode when it meets Mars.
Harmful combustion products:
Fire extinguishing method: water, foam and carbon dioxide are strictly prohibited. The best way to put out the fire is to suffocate the seedlings with dry graphite powder and dry sand to isolate the air. Protect your eyes and skin during rescue to avoid flying particles burning your body and magnesium light burning your eyesight.
Part VI: Return to the directory of emergency response to leakage.
Emergency treatment: isolate the leaked contaminated area and restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static work clothes. Don't touch the leak directly. Small amount of leakage: avoid dust and collect it in a dry, clean and covered container with a clean shovel. Transfer and recovery. Massive leakage: covered with plastic sheets and canvas. Clean up under the guidance of experts.
Part VII: Operation, Disposal and Return to Directory
Precautions for operation: strengthen local ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear self-priming filter dust mask, chemical safety glasses and anti-static work clothes. Stay away from kindling and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Avoid dust. Avoid contact with oxidants, acids, halogens and chlorinated hydrocarbons. Pay special attention to avoid contact with water. The treatment is carried out in nitrogen. When handling, handle with care to prevent the packaging and containers from being damaged. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances behind.
Precautions for storage: Store in a cool, dry and well-ventilated warehouse. Stay away from fire and heat sources. The reservoir temperature should not exceed 30℃. The package should be sealed and not in contact with air. Should be stored separately from oxidants, acids, halogens, chlorinated hydrocarbons, etc. , and should not be mixed. Adopt explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are easy to generate sparks. The storage area should be equipped with suitable materials to control leakage.
