Final answer:
OSHA's Laboratory Standard requires that a Chemical Hygiene Plan must be available to employees, and it does not specify storage by alphabetical order, mandatory use of respirators, or nitrile gloves for all chemical handling.
Step-by-step explanation:
The Laboratory Standard, which falls under the Occupational Safety and Health Administration (OSHA), requires that a Chemical Hygiene Plan must be available to employees. This plan should address safety protocols, including the correct use of personal protective equipment (PPE), proper storage of chemicals, and procedures for handling chemical spills and accidents. It is not required by OSHA to store chemicals in alphabetical order, to use respirators when handling all hazardous chemicals, or to use nitrile gloves when handling all chemicals, as these decisions are determined by the specific hazards associated with the chemicals in use and the procedures outlined in the Chemical Hygiene Plan.
