Transportation:

1. Packaging: Sealed containers with anti-corrosion properties should be used for packaging to avoid leakage and vapor release.

2. Marking: Information about the chemical, such as name, hazardous properties, production date, etc., should be indicated on the packaging and comply with relevant regulatory standards.

3. Transportation method: Special tank trucks or containers should be selected for transportation to avoid contact with substances such as water and oxygen.

Storage:

1. Location: Dimethyl sulfate should be stored in a ventilated and dry place away from sources of fire, high temperatures, and oxidants.

2. Packaging: It should be kept sealed and protected from direct sunlight.

3. Temperature: It is recommended to store at room temperature or under low temperature conditions.

The above are some main aspects that need to be noted during the transportation and storage of dimethyl sulfate.

When using dimethyl sulfate, the following precautions should be taken:

1. Ventilation: Ensure use in a well ventilated area and avoid inhaling its vapors.

2. Protective equipment: Chemical protective goggles, chemical protective gloves, and protective clothing should be worn.

3. Protective measures: Avoid skin contact and inhalation of its vapors, and avoid ingestion.

4. Avoid mixing: Do not mix dimethyl sulfate with oxidants, strong bases, or organic bases.

5. Smoking and open flames are strictly prohibited in the usage area.

6. Waste disposal: Pay attention to proper disposal of waste and pollutants, and dispose of them in accordance with local regulations.

The above are some key points to note when using dimethyl sulfate.
