Even if not a physical drill, a tabletop review with the designated response personnel would also suffice to meet this best practice requirement (when not already required by local regulations).这里的a tabletop review是什么

"A tabletop review" refers to a type of emergency preparedness exercise in which key personnel gather together to discuss and practice their response to a simulated emergency scenario. This type of exercise is typically conducted in a classroom or conference room setting, rather than in the field, and is designed to test the response plan and identify any gaps or areas for improvement.
