Which statement describes the notification requirements for ESS commissioning and decommissioning?

• A. Notifications to authorities, stakeholders, and emergency responders with details of the process and timelines.
• B. No notifications are needed.
• C. Only internal staff.
• D. Only after the process is complete.

Answer: (A)

Commissioning and decommissioning an ESS involves notable hazards and changes to the building systems, so notifying the right people before work starts keeps everyone safer. The best approach is to alert authorities, stakeholders, and emergency responders with clear details about what will be done and the timeline. That way, responders know what to expect, where the equipment is, what hazards may be present (such as flammable refrigerants or high-energy components), and how the work will progress. It also helps ensure permits, access, shutoffs, and safety procedures are coordinated in advance, reducing the risk of surprises during the process.

Notifying only internal staff misses external parties who may need to respond to incidents or coordinate safety actions. Waiting until after the process is complete misses the opportunity to manage risks during commissioning or decommissioning. And saying no notifications are needed ignores the safety and regulatory benefits of proactive communication.
