In what situation should new or revised MSDSs be made accessible to employees?

New or revised Material Safety Data Sheets (MSDSs), now referred to as Safety Data Sheets (SDSs), should be accessible to employees at the start of every work shift to ensure that they have the most current information regarding the hazardous materials they may encounter in the workplace. This access is crucial for maintaining a safe working environment, as the employees can review any updates or new information about chemical hazards, handling procedures, and emergency measures before they commence their tasks.

By making these documents available at the beginning of each shift, organizations allow employees to prepare adequately and adhere to safety protocols. This practice aligns with regulations set by Occupational Safety and Health Administration (OSHA) concerning the right-to-know laws, which promote awareness and preventive measures related to workplace hazards.

Other scenarios, such as only providing access on weekends, during evaluations, or when a product is purchased, do not ensure continuous awareness and preparedness among employees regarding hazardous materials. Consistent, timely access to updated safety information is essential for fostering safety and compliance in the workplace.
