Which of the following is NOT a listed required element on HCS labels?

• A. Chemical Formula
• B. Product Identifier
• C. Pictogram
• D. Hazard Statement

Answer: (A)

Under the OSHA Hazard Communication Standard aligned with GHS, labels must convey hazards using a standard set of elements: the product identifier (the name used to identify the chemical or mixture), one or more pictograms, hazard statements that describe the specific hazards, a signal word, precautionary statements, and the supplier’s information. The chemical formula is not a mandated element on HCS labels; it isn’t required to communicate the hazards and is more typically found on safety data sheets or in the chemical’s full name. So the chemical formula is the correct choice as NOT required on labels. The other elements—product identifier, pictogram, and hazard statement—are all required to ensure workers can recognize the substance and understand the hazards at a glance.
