Which factor determines when notifications must be made for a release?

• A. Materials and quantities
• B. Type and rate
• C. Location and time
• D. Severity and duration

Answer: (A)

Notifications are driven by what the chemical is and how much of it is released. Some substances have strict reporting thresholds because even a small release can create significant danger, while others only trigger notification if the released amount crosses a defined threshold. The rules set by regulators specify these thresholds for each material, and you compare the actual release quantity to that threshold to decide if a notification is required. The rate, duration, location, or time of the release might influence how urgently you alert and whom you notify, but they don’t establish whether notification is required in the first place.
