OSHA requires that a copy of what must be readily available to all employees?

The correct answer is that OSHA requires a copy of the hazard communication program and Safety Data Sheets (SDS) to be readily available to all employees. This requirement is part of the OSHA Hazard Communication Standard, which aims to ensure that workers are informed about the hazardous chemicals they may encounter in their workplace. Providing accessible information on hazardous substances allows employees to understand the risks associated with these chemicals and how to protect themselves effectively.

SDS sheets, in particular, are crucial as they provide detailed information about the properties of each chemical, including handling, storage, and emergency procedures. The availability of this information empowers employees to make safer choices while working and ensures compliance with safety regulations.

In contrast, while employee handbooks, emergency plans, and training manuals are important for different aspects of workplace safety and operations, they are not specifically mandated by OSHA to be available in the same way that the hazard communication program and SDS sheets are. This focus reflects the priority OSHA places on chemical safety and proper communication regarding workplace hazards.
