When should a chemical container be labeled or marked?

A chemical container should be labeled or marked immediately upon transfer to ensure proper identification and safety throughout the handling process. This practice is crucial because it provides clear information about the contents of the container, including any potential hazards associated with the chemical. Proper labeling helps prevent mishandling, accidental exposure, and ensures that employees can easily identify and manage hazardous substances. Compliance with this standard not only promotes workplace safety but also aligns with regulatory requirements regarding chemical safety and labeling. This proactive approach supports a safer work environment by minimizing risks associated with chemical exposure.
