Read： 655 Time：17months ago Source：Transform the World with Simplicity

N,N-dimethylacetamide (DMAC) is a common chemical raw material, which is widely used in medicine, pesticide, plastic, fiber and other fields. Due to its toxicity and flammability, strict compliance with relevant safety regulations is required during storage and transportation. This paper will detail the safe storage and transportation specification of DMAC.

1. safety storage specifications

1. Storage environment requirements
DMAC should be stored in a dry, cool, well-ventilated indoor environment, avoiding direct sunlight and high temperature. The storage temperature should be controlled below 25 ℃, and the relative humidity should not exceed 75%.

2. Storage container requirements
DMAC should use a special sealed container storage, container material should have corrosion resistance and sealing. The container shall be marked with the name of the DMAC, its hazards and storage precautions.

3. Storage location requirements
DMAC should be stored on a shelf or platform with a height of not less than 50cm from the ground, avoiding close to fire, heat and power sources. The storage area shall be provided with obvious safety warning signs and fire protection facilities.

4. Storage management requirements
storage area should establish a strict management system, no smoking and open fire, regular safety inspection and maintenance. Storage personnel should be professionally trained to understand the nature and safe operating procedures of DMAC.

2. Transport Code

1. Transport Vehicle Requirements
DMAC should use special dangerous goods transport vehicles for transport, vehicles should comply with relevant national standards, with explosion-proof, fire prevention, leakage prevention and other safety measures.

2. Transport packaging requirements
DMAC packaging should comply with relevant national standards, with corrosion resistance, good sealing, high compressive strength. The package shall be marked with DMAC name, danger, transportation precautions and emergency contact number.

3. Transportation route requirements The transportation route of
DMAC should choose a safe and reliable route to avoid passing through densely populated areas, important facilities and other sensitive areas. During transportation, traffic rules should be observed, speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided.

4. Transportation personnel management requirements
transportation personnel should undergo professional training, understand the nature of DMAC and safe operation procedures, and have the ability to deal with emergencies. In the process of transportation, communication shall be kept unblocked and the transportation situation shall be reported in time.

3. emergency treatment measures

1. skin contact: immediately take off contaminated clothing, rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

4. conclusion

N,N-dimethylacetamide (DMAC) as a common raw material for chemical production, its safety and standardization of storage and transportation are very important. In the storage process, it is necessary to strictly control the environmental conditions and follow the storage management requirements; in the transportation process, special vehicles and packaging should be selected, traffic rules should be observed, and communication should be kept smooth. By strictly complying with these specifications, the safe storage and transportation of DMAC can be ensured, and the safety of production and the health of personnel can be guaranteed.
