Which party is responsible for reporting suspicious or unusual activities involving controlled chemicals?

• A. The end-user.
• B. The supplier.
• C. The general public.
• D. The license holder or operator to the regulatory authority.

Answer: (D)

The obligation rests with the license holder or operator because they are legally responsible for the facility’s compliance with chemical control rules and for safeguarding controlled substances. They are the ones who oversee how chemicals are procured, stored, handled, and used, so they’re in the best position to notice anomalies—like unusual purchase patterns, unexpected changes in storage, signs of tampering, or transfers that don’t fit normal operations. When something suspicious is detected, they must report it to the regulatory authority promptly to trigger formal review, risk assessment, and any necessary corrective actions. While others—end-users, suppliers, or the general public—may notice odd activity and can report it, the formal, responsible party for initiating regulatory notification is the license holder or operator.
