If a victim appears to be having an allergic reaction, where could you locate information about product usage?

• A. SDS
• B. MDS
• C. DMS
• D. SMD

Answer: (A)

Understanding where to find product usage and safety guidance in an allergic reaction is about the Safety Data Sheet. The SDS is the official reference that accompanies chemical and cosmetic products, and it provides first aid measures, ingredient information, and emergency procedures. In the moment of a reaction, you can consult the SDS to know exactly what to do for exposure—how to treat skin or eye contact, what to monitor for (like breathing issues), and when to seek medical help—plus it often lists the manufacturer’s contact for urgent questions. The other terms aren’t standard safety documents used for salon products, so they wouldn’t reliably give the necessary usage and hazard information. If the reaction seems serious, call emergency services right away.
