Packaging, transportation and safety

Packing method:Small open steel barrels; Ordinary wooden cases outside ampoules; Ordinary wooden cases outside threaded glass bottles, iron cap pressure glass bottles, plastic bottles or metal barrels (cans).

Transport notes:Railway transportation shall be carried out in strict accordance with the dangerous goods loading table in the Regulations of the Ministry of Railways on the Transport of Dangerous Goods. During transportation, the transportation vehicles shall be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. recommend morning and evening transportation in summer. The tank (tank) truck used in transportation shall be provided with grounding chain, and the hole partition plate can be set in the tank to reduce static electricity generated by vibration. It is strictly prohibited to mix with oxidants, acids, alkalis, edible chemicals, etc. During transportation, it shall be protected from sun exposure, rain and high temperature. Stopover should be away from fire, heat, high temperature zone. The exhaust pipe of the vehicle carrying the goods must be equipped with fire retardant device, and it is forbidden to use mechanical equipment and tools that are easy to produce sparks for loading and unloading. Road transportation shall be carried out according to the prescribed route, and do not stop in residential areas and densely populated areas. It is forbidden to slip away during railway transportation. It is strictly prohibited to use wooden ships and cement ships for bulk transportation.

Storage Precautions:Store in a cool, ventilated warehouse. Keep away from fire and heat source. The temperature of the warehouse should not exceed 30 ℃. Keep container sealed. Should be stored separately with oxidants, acids, alkalis, do not mix storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

Operation Precautions:Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filtering respirator (half mask), chemical safety goggles, anti-static overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidants, acids and alkalis. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle and unload lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

Health Hazards:On the eyes and upper respiratory tract have a strong stimulating effect, there is an anesthetic effect. Inhalation of high concentrations of this product may cause tearing, sore throat, cough, chest tightness, shortness of breath, etc. In severe cases, cardiovascular and neurological symptoms may occur. Can cause conjunctivitis, keratitis, corneal epithelial vacuole formation. Skin contact can cause skin dryness.

First aid measures

Skin contact: remove contaminated clothing and rinse skin thoroughly with soap and water.

Eye contact: immediately lift the eyelid and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.

Inhalation: quickly leave the scene to fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention. Intake: Drink plenty of warm water to induce vomiting.

Fire protection measures

Hazardous characteristics: flammable, its vapor and air can form an explosive mixture, fire, high heat caused by combustion explosion. Can react strongly with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower point, and it will catch fire and backburn in case of a fire source.

Hazardous combustion products: carbon monoxide, carbon dioxide.

Fire extinguishing method: use anti-soluble foam, carbon dioxide, dry powder and sand to extinguish the fire. Fire extinguishing with water is ineffective, but water can be used to keep the container cool in the fire.

Emergency treatment of leakage

Quickly evacuate the personnel from the leakage pollution area to the safety area, isolate them and strictly restrict the access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static overalls. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: with activated carbon or other inert material absorption. It can also be washed with a large amount of water and diluted with washing water into the waste water system. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Transfer to tanker or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.
