Which of the following is a key step in the ESS decommissioning process?

• A. Site assessment
• B. Equipment upgrade planning
• C. New installation
• D. Emergency response training

Answer: (A)

A site assessment is the essential first step because it builds the factual understanding of what exists and what hazards are present before any decommissioning work begins. By evaluating the current conditions—what equipment and refrigerant are there, electrical and fuel sources, ventilation, fire protection, access and egress, nearby ignition sources, structural constraints, and applicable permits—you establish the scope, sequencing, and safety controls needed for decommissioning. This baseline informs how you isolate energy, plan refrigerant recovery or disposal, and determine necessary protective measures. Other activities like upgrading equipment, adding new installations, or focusing solely on emergency response training are important in different contexts or later stages, but they don’t define the appropriate initial approach the moment you start decommissioning.
