Final answer:
The Laboratory Standard requires a Chemical Hygiene Plan to be available to employees, ensuring that they are aware of chemical hazards and safety measures in the lab.
Step-by-step explanation:
One of the requirements of the Laboratory Standard is that a Chemical Hygiene Plan must be available to employees. This helps ensure that employees are informed about chemical hazards and understand the procedures and safety measures in place to minimize exposure and risks in the laboratory. Storing chemicals in alphabetical order, the mandatory use of respirators, or specifying that nitrile gloves must be used when handling all chemicals are not universal requirements of the Laboratory Standard. Rather, the appropriate personal protective equipment (PPE) depends on the specific chemical being handled and its associated risks.
