Which of the following is typically NOT found on a chemical label?

The typical content of a chemical label is designed to provide essential safety information and guidance regarding the chemical's identity and handling. Among these, emergency contact information, manufacturer's name, and storage instructions are crucial components that contribute to safe usage and management of the chemical.

Emergency contact information is vital in case of an accident or exposure, providing quick access to resources or personnel who can assist. The manufacturer's name is important for identifying the source of the chemical, allowing users to obtain further details or safety data if necessary. Additionally, storage instructions guide users on how to properly store the chemical to prevent accidents or degradation.

In contrast, chemical composition refers to the specific formulas or constituents of the substance and is typically found in a Safety Data Sheet (SDS) rather than on the label itself. Labels focus on immediate safety information and handling guidelines, while detailed composition is reserved for the SDS, which provides comprehensive information about the chemical's properties, hazards, and safe handling practices. Therefore, the absence of chemical composition from a chemical label is consistent with regulatory standards and safety practices.
