Question

question 2
the following practices must be avoided while working in a biology lab, except:
throwing broken glass into a glass - only container
lighting a bunsen burner when the instructor is not in the lab
dissecting animals without gloves
wearing open - toe footwear
bringing food or beverage into lab

Explanation:

• Throwing broken glass into a glass - only container is a proper safety practice. It helps in safe disposal of glass waste and prevents injuries.
• Lighting a Bunsen burner when the instructor is not in the lab is dangerous as one might not handle it correctly (e.g., wrong gas - air ratio) leading to accidents like fires or explosions.
• Dissecting animals without gloves can expose one to biological hazards (e.g., pathogens from the animal).
• Wearing open - toe footwear in a lab is unsafe as there is a risk of spills (chemical or biological) or dropping of heavy objects on the feet.
• Bringing food or beverage into the lab can lead to contamination (either of the food by lab substances or vice - versa if it's a biological lab with potential pathogens).

Answer:

throwing broken glass into a glass - only container
