Read： 971 Time：14months ago Source：Transform the World with Simplicity

Methyl propylene glycol (Propanediol, referred to as MPD) is a common chemical production raw materials, widely used in coatings, inks, cleaning agents, plastics and other industries. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safe storage and transportation specifications of methyl propylene glycol.

1. the physical and chemical properties of methyl propylene glycol

Methyl propylene glycol is a colorless and transparent liquid with a slight special smell. It is soluble in water, ethanol, ether and other organic solvents, but insoluble in aliphatic hydrocarbons. Methyl propylene glycol has a low flash point, is flammable, and may form an explosive gas when mixed with air. In addition, methyl propylene glycol has an irritating effect on the eyes, skin and respiratory tract, and prolonged contact may cause skin allergies and respiratory diseases.

2. safety of methyl propylene glycol storage specification

1. storage site requirements: methyl propylene glycol should be stored in a cool, dry, well-ventilated warehouse, away from fire, heat. Fire fighting equipment and leakage emergency treatment equipment shall be set in the warehouse.
2. Storage container requirements: Methyl propylene glycol should be stored in a special stainless steel or plastic container to avoid the use of iron, aluminum and other metal containers to prevent chemical reactions.
3. Storage limit requirements: According to relevant national regulations, the storage of methyl propylene glycol should be controlled within a certain range and should not exceed the prescribed limit.
4. Management requirements: Warehouse management personnel should be professionally trained to understand the nature of methyl propylene glycol and safe operation procedures to ensure storage safety.

3. safety of methyl propylene glycol transport specification

1. transport vehicle requirements: methyl propylene glycol should be used for tanker or truck transport, vehicles should comply with the relevant national regulations and standards, with a valid transport license.
2. Transport packaging requirements: The packaging of methyl propylene glycol should be firm and sealed to prevent leakage. The packaging shall be clearly marked with the name of the goods, the nature of the hazard, emergency measures and other information.
3. Transportation personnel requirements: transportation personnel should be professionally trained to understand the nature of methyl propylene glycol and safe operation procedures to ensure transportation safety.
4. Requirements for transportation route: The transportation route of methyl propylene glycol shall be a route with smooth roads, convenient transportation, and far away from residential areas and open fire areas. During transportation, long-term parking should be avoided to ensure that the goods reach the destination in time.

4. of methyl propylene glycol leakage emergency treatment measures

1. immediately cut off the source of leakage, close the valve or take other measures to prevent leakage.
2. Mix the spill with sand, dry lime or soda ash and collect it in a special container.
3. Avoid leakage into restricted spaces such as sewers and drains.
4. If a large amount of leakage occurs, report to the local environmental protection department immediately, and take preventive measures to prevent the occurrence of fire and poisoning accidents.

5. summary

of methyl propylene glycol as a common chemical production raw material, in the process of storage and transportation need to strictly abide by the relevant norms to ensure safety. By understanding the physical and chemical properties of methyl propylene glycol, safety storage and transportation specifications, and leakage emergency treatment measures, the accident risk can be effectively reduced, and the safety of production and personnel health can be guaranteed.
