What additional information is required on shipped containers apart from the label?

The correct choice highlights the importance of providing contact information for key responsible parties responsible for the materials being shipped. This information is crucial because it allows individuals to reach out in case of emergencies, accidents, or when additional information regarding the chemical is required. In environments where hazardous materials are handled, having a contact available can facilitate quick responses and promote safety.

Including the name, address, and telephone number of the responsible parties helps ensure proper communication regarding the chemical’s hazards and handling requirements. It aligns with OSHA’s emphasis on transparency and accessibility of information about hazardous substances, which is critical for ensuring the safety of workers and emergency responders.

The other options contain pertinent information that might be helpful in certain contexts but are not specifically mandated to be included on shipping labels under OSHA regulations. For instance, safety instructions may be necessary for the proper use of a chemical but are generally provided in safety data sheets rather than on the container label. Color codes of chemicals can assist with quick visual identification but are not a requirement for packaging. Detailed chemical compositions, while informative, are usually outlined in safety data sheets as well, and not all formulations need to be disclosed directly on the shipping containers.
