What are close-toed shoes least likely to provide protection against?

a. hydrogen gas produced during a reaction
b. spilled water from a hot water bath
c. broken glass from a dropped test tube
d. acid leaking from a cracked beaker

Ans: A

While working in a chemical laboratory one often encounters hazardous chemicals that may come in contact with the skin and cause injuries. Along with a proper lab coat it is important to protect the feet as well. Hence, closed toe shoes provide protection against spilled water from a hot water bath, broken glass dropped from a test tube and acid leaking from a cracked container.

Gases on the other hand can permeate through shoes, thus close-toed shoes least likely to provide protection against  hydrogen gas produced during a reaction.
