Which of the following describes an appropriate safety precaution that students must take when heating water in a beaker?

Wearing appropriate safety equipment, such as a lab apron, safety goggles, and closed-toe shoes, is essential when performing any heating experiment in a laboratory setting, including heating water in a beaker. The lab apron protects clothing from spills or splashes, while safety goggles shield the eyes from potential hazards, such as hot water or steam that might escape unexpectedly. Closed-toe shoes provide additional protection for feet in case of spills or dropped equipment.

By emphasizing these precautions, students ensure their safety and the safety of others in the lab environment. This practice aligns with standard laboratory safety protocols, which stress the importance of protecting oneself against the risks associated with heating substances. Engaging in these safety measures prepares students to handle laboratory equipment responsibly and effectively.
