Which of the following statements reflects appropriate laboratory safety standards?

The statement regarding the emergency shower being located within a travel time of 10 seconds reflects appropriate laboratory safety standards because it emphasizes the importance of quick access to safety equipment. In the event of a chemical spill or exposure, immediate decontamination is crucial to minimizing injury. Having an emergency shower readily accessible within a short distance ensures that individuals can respond swiftly and effectively to accidents, thereby enhancing safety protocols within the laboratory environment.

In contrast, other options do not align with comprehensive safety standards. For instance, prescription eyeglasses are not adequate for eye protection in a lab setting, as they do not provide the necessary shield against potential hazards like chemical splashes or flying debris. Similarly, wearing short pants is not considered safe attire for a laboratory, where skin exposure could lead to chemical burns or injury. Finally, while closed-toe shoes are appropriate footwear, the statement as a standalone measure does not fully encapsulate the broad range of protective attire recommended in a lab, such as lab coats or gloves. Overall, the balance of immediate access to emergency equipment and adequate protective measures is essential in maintaining a safe laboratory environment.
