TeXes Science Practice Test

Which practice is considered poor hygiene in a laboratory setting?

1. Wearing gloves during experiments

2. Use laboratory glassware for eating or drinking purposes

3. Cleaning work surfaces before use

4. Storing food in the laboratory fridge

The correct answer is: Use laboratory glassware for eating or drinking purposes

Using laboratory glassware for eating or drinking purposes is considered poor hygiene in a laboratory setting because it poses a significant risk of cross-contamination and exposure to hazardous substances. Laboratory glassware is designed for conducting experiments and may contain chemical residues or biological materials that could be harmful if ingested. Consuming food or drinks from items intended for scientific use can also lead to the introduction of contaminants into the food or drink, which can result in serious health risks. In a lab environment, maintaining a strict separation between eating and experimental activities is crucial to ensure safety and health. Practices such as wearing gloves during experiments, cleaning work surfaces before use, and storing food properly in designated areas are essential for maintaining hygiene and preventing contamination. These practices contribute to a safe laboratory environment and help protect individuals from the risks associated with laboratory materials.
