Which of the following is a safety measure against chemical exposure?

Wearing gloves is a critical safety measure against chemical exposure because they provide a barrier between the skin and harmful substances. Chemicals can cause various health hazards, including skin irritation, burns, or systemic toxicity if they come into contact with the skin. Gloves made of appropriate materials offer protection tailored to the specific chemicals being handled, thereby reducing the risk of chemical injuries and exposures during tasks such as mixing, transferring, or applying substances in a work environment.

In contrast, the other options do not provide suitable protection. Flip-flops, casual attire, and sunglasses do not offer any significant protection against chemicals, which could lead to serious health issues. Appropriate personal protective equipment (PPE), such as gloves, is essential in ensuring a safe working environment where employees interact with hazardous materials.
