Ethylene glycol safety storage and transportation specification

ethylene glycol (ethylene, referred to as EG) is a common chemical production raw material, widely used in refrigeration, solvents, antifreeze and other fields. However, ethylene glycol has certain toxicity and flammability, so it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications for ethylene glycol.

1. the toxic
of ethylene glycol
ethylene glycol is toxic to the human body. After ingestion, it will cause poisoning symptoms, including vomiting, diarrhea, coma, convulsions, etc. In severe cases, it can be fatal. In addition, ethylene glycol is also irritating and corrosive, causing pain and burns on contact with the skin or eyes.

2. glycol storage specifications

1. The storage place should be dry, ventilated, and cool, avoiding direct sunlight and high temperature.
2. The storage container shall be well sealed to prevent ethylene glycol leakage and volatilization.
3. The storage area shall be provided with obvious warning signs and safety tips, and fireworks and open fire operations are prohibited.
4. The storage area shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.

3. ethylene glycol transport specification

1. transport vehicles should comply with the relevant standards, with anti-leakage, anti-static, fire and other functions.
2. During transportation, it should be kept stable, avoid violent vibration and collision, and prevent glycol leakage.
3. During transportation, the temperature should be strictly controlled to avoid high temperature decomposition or freezing of ethylene glycol.
4. Special personnel shall be assigned to escort during transportation to ensure transportation safety.

4. glycol leakage emergency treatment

1. In case of glycol leakage, the leakage source should be cut off immediately, and the residual liquid should be absorbed by sand, dry lime or soda ash.
2. When there is a large amount of leakage, a dam or a pit shall be constructed to accommodate it and be transferred to the tank car or special collector by pump.
3. Ventilate the polluted ground, flush the ground with a large amount of water, and put the diluted sewage into the waste water system.
4. Ventilate the leakage area to avoid accumulation of glycol vapor.

5. of ethylene glycol operation precautions

1. Operators should be professionally trained to understand the nature of ethylene glycol and safe operation procedures.
2. Wear protective gloves, goggles and other personal protective equipment during operation to avoid direct contact with ethylene glycol.
3. Obvious warning signs and safety tips shall be set up in the operation area, and fireworks and open fire operations are prohibited.
4. Good ventilation should be maintained during operation to avoid accumulation of glycol vapor.

6. Glycol packaging and labeling requirements

1. Glycol packaging containers should meet relevant standards and have sufficient strength and sealing performance.
2. The name, purity and manufacturer of ethylene glycol shall be marked on the packaging container.
3. The packaging container should be set up with obvious danger signs and safety tips, indicating flammable, toxic and other hazards.

In short, ethylene glycol is a common raw material for chemical production, and its safety and standardization of storage and transportation are very important. During the operation, relevant specifications and standards should be strictly observed to ensure personnel safety and product quality.
