Planning aid based on recognised crowd-safety guidance — not a substitute for a professional crowd risk assessment, formal egress calculation, or local regulations.
The health check runs your event through every other tool at once — capacity and density, exit clearance, staffing and Martyn's Law tier — and combines them into a single readiness picture with a prioritised fix-list.
Crowd safety fails at the weakest link. A venue can have ample floor area but too few exits, or enough staff but no evacuation plan. Seeing every factor together is the only way to catch the gap a single number would hide.
- Use realistic worst-case numbers — peak attendance, full bar, the headline moment.
- Fix the red items first; they're the ones most likely to cause a crush.
- Re-run it after any change to layout, capacity or programme.
