It is always safe to wear what kind of shoes during an expirment?
- A.
Sandals
- B.
None
- C.
Closed toe shoes
Correct Answer
C. Closed toe shoesExplanation
Closed toe shoes are the safest option to wear during an experiment because they provide protection to the feet. They cover the entire foot, including the toes, which reduces the risk of injury from falling objects, spills, or chemical splashes. Sandals, on the other hand, leave the toes exposed and provide minimal protection. Not wearing any shoes at all is also unsafe as it leaves the feet vulnerable to potential hazards in the lab environment. Therefore, closed toe shoes are the most appropriate choice for ensuring safety during an experiment.Rate this question:
