What information must be included on a new label if the original hazardous chemical label is removed or illegible?

The correct answer emphasizes the necessity for comprehensive labeling to ensure safety and compliance with regulations regarding hazardous chemicals. When the original label is removed or becomes illegible, the new label must convey essential information that provides users with adequate data to handle the chemical safely.

Including hazard identification on the new label is critical because it informs individuals about the potential dangers associated with the chemical, which is vital for taking appropriate precautions. Additionally, manufacturer information is necessary to trace the source of the chemical, facilitate communication regarding safety data, and allow for reporting in case of an emergency or incident.

This requirement is aligned with regulatory standards, such as those set by OSHA, which mandate that labels must contain not only the name of the chemical but also pertinent details regarding the hazards and the manufacturer's identity. This ensures that all personnel can recognize and manage the associated risks effectively.

The other choices provided fall short of encompassing the required information, which is crucial for maintaining safety standards and regulatory compliance in environments where hazardous substances are used.
