Propylene glycol safety storage and transportation specification

1. Introduction

Propylene glycol is a common chemical production raw materials, widely used in food, medicine, cosmetics and other fields. However, if the storage and transportation of propylene glycol is not standardized, it may cause safety accidents and cause harm to human health and the environment. Therefore, the purpose of this paper is to explore the safety storage and transportation specifications of propylene glycol to ensure production safety and personnel health.

2. Propylene Glycol Properties and Hazard

Propylene Glycol is a colorless, odorless, transparent liquid with strong hygroscopicity and solubility. It has an irritating effect on the skin and eyes, and long-term contact or inhalation of propylene glycol vapor may cause harm to the human body. In addition, propylene glycol is also flammable, in case of open flame, high heat or oxidant contact, there is a risk of combustion and explosion.

3. propylene glycol safety storage specification

1. storage place should choose cool, ventilated, dry place, away from open flame, heat source and oxidant.
2. Storage containers shall be well sealed to prevent leakage and volatilization.
3. The storage area shall be provided with fire fighting equipment and leakage emergency treatment equipment.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. propylene glycol safety transport specification

1. Transport vehicles should have the corresponding qualifications and certificates, the driver should be professionally trained.
2. Keep running smoothly during transportation to avoid severe vibration and collision.
3. Propylene glycol should be transported separately from oxidants, acids and edible chemicals, and mixed storage and transportation should not be allowed.
4. During transportation, the goods shall be inspected regularly and any abnormal situation shall be handled in time.

5. propylene glycol leakage emergency treatment

1. found propylene glycol leakage, should immediately stop the operation, close the source of leakage.
2. Absorb the spill with a mixture of sand, dry lime or soda ash and collect it in a sealed container.
3. In case of a large amount of leakage, embankments or pits shall be constructed and covered with foam to reduce steam disasters.
4. Ventilate the leakage area to ensure air circulation.
5. If you ingest or inhale propylene glycol, you should seek medical treatment immediately.

6. Training and Management

1. Conduct professional training for staff engaged in the storage and transportation of propylene glycol to improve their safety awareness and operational skills.
2. Establish a sound management system for the storage and transportation of propylene glycol, and clarify the job responsibilities and operating specifications.
3. Conduct regular safety inspection and evaluation, and timely discover and rectify potential safety hazards.

7. conclusion

propylene glycol as a common chemical production raw material, its safe storage and transportation is very important. By understanding the nature and hazards of propylene glycol, strictly abiding by storage and transportation norms, strengthening the work of emergency treatment, training and management of leakage, production safety and personnel health can be effectively guaranteed. Therefore, all relevant units should strengthen the safety management of propylene glycol storage and transportation to ensure the stable development of chemical production.
