What does the "signal word" in the hazard identification section of an SDS indicate?

The signal word in the hazard identification section of a Safety Data Sheet (SDS) serves to communicate the level of urgency and potential danger associated with the chemical's hazards. It typically indicates the severity of the hazards, helping users understand the risk involved. The use of terms like "Danger" or "Warning" signifies different levels of hazard; "Danger" suggests a more severe risk compared to "Warning," which indicates a lesser but still significant risk. This immediate recognition is crucial for ensuring safety in handling, storage, and emergency response.

The other options do not directly relate to the purpose of the signal word. While compliance status with safety regulations is important, it is not conveyed by the signal word. Similarly, the reputation of the manufacturer or details about possible replacements for the chemical are not indicated by the signal word, as they pertain to other aspects of product information rather than hazard communication.
