Under OSHA's Hazard Communication Standard, what does Appendix B focus on?

Appendix B of OSHA's Hazard Communication Standard specifically addresses the process for determining and classifying physical hazards associated with chemicals. This section is vital because it outlines the criteria for identifying the potential risks that a chemical may present based on its physical properties, such as flammability or reactivity. The classification guidance helps employers understand how to evaluate the hazards related to the chemicals they handle, ensuring that proper precautions, labeling, and safety measures are implemented to protect employees. By focusing on this aspect, Appendix B plays a key role in enhancing workplace safety by ensuring that hazards are recognized and communicated effectively.
