Diluent is neither a hazardous material nor a dangerous chemical, but relevant safety measures still need to be observed during use to prevent accidents.
1. Concept 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, medical, and cleaning, but they differ from hazardous materials and dangerous chemicals.

Hazardous materials refer to items that may pose potential harm to people, property, and the environment during transportation, handling, and storage, characterized by flammability, explosiveness, toxicity, corrosiveness, etc. In contrast, dangerous chemicals refer to chemicals that can cause explosions, combustion, poisoning, corrosion, or other hazards, including hazardous chemicals and chemical products.

In this sense, diluents are neither hazardous materials nor dangerous chemicals; they are simply substances used to dilute other substances and do not possess the above characteristics. However, during the use of diluents, their impact on humans and the environment and safety measures must still be considered to prevent potential risks and accidents.

2. Properties and Uses
Diluents generally have stable properties, with a neutral or near-neutral pH value, and some have certain volatility. Depending on different uses and needs, various diluents can be used. Generally, they can be applied in the following areas:

1. Industry and Laboratory: Used to dilute paints, clean equipment and materials, adjust concentrations in experiments, etc.

2. Medicine: Used to dilute drugs, prepare injections, etc.

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

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

3. Safety Measures
Although diluents are neither hazardous materials nor dangerous chemicals, safety measures must still be observed during use to ensure user safety:

1. Protective gloves, masks, and other protective equipment must be worn during use, especially when using toxic diluents.

2. Avoid improper use of diluents and incorrect handling that may lead to accidents.

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

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