Danger of ignition and explosion: this product is non-flammable, poisonous and irritating.
Part four: first aid measures
Skin contact: remove contaminated clothing and rinse with plenty of running water.
Eye contact: lift eyelids and rinse with running water or normal saline. Go to a doctor.
Inhalation: quickly remove from the scene to fresh air. Keep your airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Go to a doctor.
Ingestion: drink plenty of warm water to induce vomiting. Gastric lavage, drainage. Go to a doctor.
Part five: fire control measures
Dangerous properties: oxidizing. Exposure to organic matter poses a risk of combustion.
Harmful combustion products: nitrogen oxides, ammonia.
Fire fighting method: the fireman must wear the whole body fire protection clothing, in the upwind fire fighting. When extinguishing a fire, remove the container from the fire site to an open area as much as possible. Then choose the appropriate extinguishing agent according to the cause of fire.
Part six: emergency treatment of leakage
Emergency treatment: isolate the contaminated leakage area and restrict access. Emergency personnel are advised to wear dust masks and gas protective clothing. Do not come into direct contact with leaks. Small leakage: carefully sweep and collect in a closed container. Large leakage: collection and recovery or transport to waste disposal sites for disposal.
Part seven: handling and storage
Operation precautions: closed operation, 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 operators wear self-suction filter dust respirator, chemical safety protective glasses, protective clothing and rubber gloves. Keep away from inflammable, flammable materials. Avoid dust. Avoid contact with reducing agents. Equipped with leakage emergency treatment equipment. An empty container may contain harmful residue.
Store in cool and ventilated warehouse. Keep away from fire and heat. Keep out of direct sunlight. Packing seal. Should be stored separately with reducing agent, easy (can) combustible substance, edible chemical, avoid mixed storage by all means. Appropriate materials should be available in the storage area to contain leaks.
