Final answer:
It is false that unlined rubber gloves should be used for mixing wet chemicals; instead, PPE including gloves, goggles, and if necessary, full body suits, should be used to properly protect against chemical hazards.
Step-by-step explanation:
It is false that unlined rubber gloves should be used for mixing wet chemicals. In a laboratory environment, personal protective equipment (PPE) is crucial for safety. Materials such as chemicals may be hazardous if in extended contact with the skin, hence hand washing with soap is important after handling these materials. Appropriate gloves, safety goggles, and safety aprons are essential PPE. Specifically for handling dangerous substances like chlorine, adequate protection such as full body suits, gloves, and full face masks are recommended. Using unlined gloves could lead to chemical exposure through permeation or degradation of the glove material. Lined gloves designed for chemical resistance are more appropriate for this use.
