b. loose clothing and jewelry is more likely to impede movement, or accidentally knock materials over, causing a spill or other accident.
c. in the event of a spill or spray of reagent, all of these items are likely to hold the chemical close to the skin, making it harder to remove and therefore increasing the risk of injury.

Hello,

During the laboratories, a high dexterity is required, thus, such accessories,  when you move or change your duty, could touch other materials or act out of your control resulting in spillages and constricting your proper movements and skills, that is why considering the lab safety policy, we must take those artifacts away from the chemistry lab.

Best regards.
