Sodium chloride (NaCl), commonly known as table salt, does not have any WHMIS symbols. This is because it is generally considered a non-hazardous material in its common form.

Here's why:

* Low Toxicity: Sodium chloride is essential for human life and is consumed regularly. In small amounts, it poses no significant health hazard.

* Non-Flammable: It is not combustible and does not react violently with other substances.

* Non-Corrosive: It does not corrode metals or other materials.

However, it's important to note that:

* High Concentrations: In very high concentrations, sodium chloride can be irritating to the skin and eyes.

* Industrial Uses: In some industrial applications, like brine solutions used in some processes, sodium chloride may require specific handling procedures.

Therefore, while generally safe, it's always a good idea to consult the Safety Data Sheet (SDS) for any specific product or form of sodium chloride you're using. The SDS will provide detailed information about potential hazards and safety precautions.
