First, map the site and list any hazards. Assign a safety lead and give every volunteer a short briefing. Keep a first aid kit and a clear evacuation route on hand, and set up a simple radio or cell‑phone chain of command. Make sure everyone knows the emergency number and the meeting point. Use PPE—gloves, masks, and good shoes—so no one gets injured. Set up checkpoints to keep the area organized and the debris out of walkways. After the event, do a quick debrief to see what worked and what needs tweaking. Stick to the plan, don’t improvise.
