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

• A. Conducting routine maintenance
• B. Alerting responders
• C. Identifying the emergency
• D. Post-incident review

Answer: (A)

The key idea is telling the difference between actions taken during an emergency and regular maintenance work. In an ESS emergency, you start by quickly recognizing what’s happening and then alert the right responders so they can come prepared. Once help is on the way, you take immediate, safe actions to protect people and contain the situation—this can include identifying exactly what is wrong, isolating the hazard if possible, shutting down affected parts of the system if it’s safe to do so, and evacuating or directing others as needed. After the incident is under control, a post-incident review helps you learn from what occurred and improve future responses. Conducting routine maintenance, while essential for preventing problems, is a normal operation activity rather than a response to an emergency. That’s why it’s not part of the emergency response sequence.
