Read： 623 Time：19months ago Source：Transform the World with Simplicity

PPD, also known as hydroquinone, is an important organic chemical raw material, widely used in dyes, pharmaceuticals, pesticides, antioxidants and other fields. However, due to its unique chemical properties, PPD poses certain safety risks during storage and transportation. In order to ensure production safety, the relevant storage and transportation regulations must be strictly observed.

1. the properties and hazards of PPD

PPD is a white or slightly yellow crystalline powder with a special pungent odor. PPD is harmful to humans and may cause skin irritation, allergies and respiratory diseases after exposure. In addition, PPD is also flammable and corrosive, and may cause combustion or corrosion of equipment when exposed to open flames, high heat or contact with oxidants.

2. PPD safety storage specifications

1. Storage facilities: PPD should be stored in a cool, dry, well-ventilated special warehouse, avoid direct sunlight. The warehouse shall be equipped with fire fighting equipment and leakage emergency treatment equipment.
2. Storage and packaging: PPD should be sealed in accordance with national standards, and the packaging materials should have good corrosion resistance and sealing properties to prevent PPD leakage.
3. Storage identification: Obvious warning identification shall be set up in the warehouse to indicate the name, harmfulness and emergency treatment measures of PPD.

3. PPD safety transport specification

1. transport vehicles: should be selected with dangerous goods transport qualification of special vehicles for transport, vehicles should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
2. Transport packaging: The transport packaging of PPD should meet national standards, have good corrosion resistance and sealing properties, and prevent PPD from leaking during transportation.
3. Transport routes: Safe transport routes should be chosen to avoid passing through densely populated areas and sensitive areas.
4. Transport personnel: Transport personnel shall undergo professional training in the transport of dangerous goods, be familiar with the nature and hazards of PPD, and master emergency treatment measures.

4. PPD leakage emergency treatment measures

1. In case of PPD leakage, immediately start the emergency treatment plan and organize professionals to deal with it.
2. A warning line shall be set up in the leakage area to prohibit irrelevant personnel from entering.
3. Use special adsorption materials to clean up the leaked PPD to avoid PPD spreading to the environment.
4. The cleaned wastes shall be disposed in accordance with national standards to prevent environmental pollution.

In short, in order to ensure the safe storage and transportation of PPD in the field of chemical production raw materials, it is necessary to strictly abide by relevant norms and standards, strengthen the training of management and operators, improve safety awareness, and ensure safety in the production process.
