Labeling of chemical containers is fundamental to effective hazard communication. The manufacturer provides compliant labeling for each chemical they sell. However, OSU labeling standards are needed for labeling secondary containers and expiration sensitive chemicals such as peroxide formers.

Labels and signage are the cornerstones of hazard communications. They provide the ability to locate and identify laboratory hazards. The guidance on this page is intended to provide unambiguous instructions regarding chemical labeling, hazardous waste labeling, entrance signage, chemical storage, location of safety equipment, and unattended experiments. Specific dimensions and ordering information can be found on the Purchasing Guide Sheet.

Proper signage at a laboratory entrance provides important information about the hazards located inside, as well as required personal protective equipment (PPE). This information is extremely valuable for responders and visitors and reminds employees of the hazards they encounter upon entering a laboratory. Signage inside the laboratory designates the locations for safety equipment, chemical storage, and unattended experiments. Standardized guidance, listed below, provides easy identification of hazards and locations of safety equipment in case of an emergency.
