Under GHS, when should HazCom labeling be updated?

• A. Only when the chemical is reformulated
• B. Whenever the hazard information is unchanged
• C. During annual compliance reviews regardless of hazard info
• D. If hazard classification changes or new hazard information becomes available, update the label and SDS accordingly

Answer: (D)

Under GHS, labeling and the Safety Data Sheet must always reflect the most current hazard information. You update the label and SDS whenever the hazard classification changes or when new hazard information becomes available. This ensures that pictograms, signal words, hazard statements, and precautionary statements accurately communicate the real risks and required protections. If new data show an additional hazard or a reclassification, the label is revised accordingly. If nothing has changed, there’s no requirement to update just for the sake of updating. The other options imply updates in scenarios where there isn’t new or changed hazard information, which isn’t the correct practice.
