Which of the following is NOT one of the four fundamental principles of laboratory work practices?

The principle of adding unnecessary ease to the lab process does not align with the fundamental principles of laboratory work practices, which prioritize safety, organization, and efficiency while minimizing risks. The focus in laboratory settings is on maintaining a safe environment and ensuring that all procedures are conducted with care and adherence to safety protocols.

Labeling chemicals clearly is essential for safety and identifying substances accurately, which prevents mishandling and potential accidents. Proper ventilation is crucial to reduce exposure to harmful fumes and maintain air quality, thereby protecting everyone in the laboratory. Minimizing exposure to hazardous materials is fundamental to safeguard health and prevent accidents or adverse reactions when working with chemicals.

In contrast, the idea of adding unnecessary ease is contrary to the safety principles that emphasize thoroughness, attention to detail, and following established procedures, rather than simplifying processes at the risk of safety or compliance.
