Read： 427 Time：12months ago Source：Transform the World with Simplicity

Propylene glycol diacetate (Propylene Glycol Diacetate, referred to as PGDA) is a common chemical raw material, widely used in coatings, inks, adhesives and other fields. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety.

1. Safety

1. Toxicity: Propylene glycol diacetate has certain toxicity. Prolonged exposure or inhalation of its vapor may cause human discomfort, such as headache, dizziness, nausea and other symptoms. Therefore, it is necessary to wear protective equipment during operation to avoid direct contact.
2. flammability: propylene glycol diacetate is a flammable liquid, encountered fire, high heat and other conditions prone to combustion or explosion. In the process of storage and transportation, it is necessary to keep away from fire, heat and other dangerous factors.

2. storage specification

1. storage place: propylene glycol diacetate should be stored in a cool, ventilated, dry special warehouse, away from fire, heat and other risk factors. The warehouse shall be equipped with fire fighting equipment and leakage emergency treatment equipment.
2. Storage container: Propylene glycol diacetate should be stored in a special stainless steel or plastic container, and iron containers should be avoided to avoid chemical reactions. The container shall be tightly sealed to prevent leakage.
3. Storage limit: The amount of propylene glycol diacetate stored should be controlled within a safe range to avoid safety risks caused by excessive storage.

3. transport specification

1. transport vehicles: propylene glycol diacetate should be transported by special dangerous goods transport vehicles, which should comply with relevant standards and have safety measures such as fire prevention and explosion prevention.
2. Transport packaging: The packaging of propylene glycol diacetate should conform to the dangerous goods packaging specifications, and the packaging should be tight and strong to prevent leakage or damage during transportation.
3. Transportation route: safe transportation route should be selected for the transportation of propylene glycol diacetate to avoid passing through densely populated areas, open fire areas and other dangerous areas.

4. emergency treatment

1. Leakage treatment: in the process of storage and transportation, such as propylene glycol diacetate leakage, should take immediate measures to deal with, to prevent pollution of the environment and endanger the safety of personnel. The leakage can be covered and collected with adsorption materials such as sand and dry lime, and then sent to the designated place for treatment.
2. Fire treatment: in case of propylene glycol diacetate fire, fire extinguishers, foam and other fire extinguishing equipment shall be used immediately to extinguish the fire, and alarm and start the emergency plan at the same time. Keep a safe distance during fire fighting to avoid casualties.

In short, propylene glycol diacetate, as a common raw material for chemical production, needs to strictly abide by relevant specifications during storage and transportation to ensure safety. By strengthening management and training, improving the safety awareness and operation skills of operators, safety risks can be effectively reduced and production safety can be guaranteed.
