Which of the following is NOT a step in the emergency response procedures for an ESS?

• A. Ensuring safety
• B. Alerting responders
• C. Calibrating sensors
• D. Post-incident review

Answer: (C)

Emergency response procedures for an ESS focus on actions that protect people and quickly control the hazard. The priority is to ensure safety, keep areas secure, and communicate with the right responders so help can arrive and the situation can be stabilized. Once the hazard is under control and the area is safe, there is typically a post-incident review to capture lessons learned and improve future responses.

Calibrating sensors, on the other hand, is a maintenance activity done under normal operating conditions, not part of the immediate emergency response sequence. During an incident you act on the sensor readings as they are, rather than recalibrating equipment, because calibration would delay critical actions and isn’t how a response is conducted.

So calibrating sensors isn’t a step in the emergency response procedures.
