Diluent is neither a dangerous goods nor a hazardous chemical, but safety measures should still be taken during use to prevent accidents.
1. Concepts and Differences
A diluent is a substance used to dilute liquids or gases in a concentrated state. Similar to chemicals, diluents can be used in various fields such as industry, laboratories, medicine, and cleaning, but they differ from dangerous goods and hazardous chemicals.

Dangerous goods refer to items that may pose potential hazards to people, property, and the environment during transportation, handling, and storage, characterized by flammability, explosiveness, toxicity, and corrosiveness. In contrast, hazardous chemicals refer to chemicals that can cause explosions, combustion, poisoning, corrosion, or other dangers, including two main categories: hazardous chemicals and chemical products.

In this sense, diluents are neither dangerous goods nor hazardous chemicals; they are merely substances used to dilute other materials and do not possess the aforementioned characteristics. However, during the use of diluents, it is still necessary to consider their impact on human health and the environment, as well as safety measures to prevent potential risks and accidents.

2. Properties and Uses
The properties of diluents are usually quite stable, with a neutral or near-neutral pH, and some have a certain degree of volatility. Depending on different uses and needs, various types of diluents can be used. Generally, they can be used in the following areas:

1. Industry and Laboratories: Used for diluting paints, cleaning equipment and materials, adjusting concentrations in experiments, etc.

2. Medicine: Used for diluting drugs, preparing injections, etc.

3. Cleaning: Used for detergents, cleaning agents, etc.

4. Others: Used to reduce the concentration of organic solvents and toxic substances, etc.

3. Safety Measures
Although diluents are not dangerous goods or hazardous chemicals, safety measures should still be observed during use to ensure the safety of users:

1. Protective gloves and masks should be worn during use, especially when using toxic diluents.

2. Avoid using inappropriate diluents and incorrect usage of diluents to prevent accidents.

3. After use, waste must be disposed of properly to avoid environmental pollution and direct contact with pollutants.

[Summary] In summary, diluents are neither dangerous goods nor hazardous chemicals, but safety measures should still be observed during use to prevent potential risks and accidents. Diluents have relatively stable properties and are widely used in various fields such as industry, laboratories, medicine, and cleaning.
