Step-by-step explanation:
The correct answer is: c) Taste chemicals to identify them.
Tasting chemicals is not a general precaution for chemical safety when working in a laboratory. It is important to never taste, smell, or touch chemicals unless specifically instructed to do so. This is because many chemicals can be harmful, toxic, or even deadly if ingested or inhaled.
Instead, it is important to always wear appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats, label all containers with the correct information to avoid confusion or accidents, and work in a well-ventilated area to prevent the buildup of harmful fumes or gases.
