Direct answerAudience scanning requires a safety calculation before the show, hardware emergency stop and interlock, beams kept above the crowd zone, and strict compliance with local limits.
Required Controls
- Complete a safety distance calculation before the effect is designed
- Fit hardware emergency stop and safety interlock that cut output immediately
- Keep beam height above the standing crowd zone except for approved scanning effects
- Follow the local limits for audience scanning operation without exception
- Brief the operator on the abort condition and the trigger for stopping the effect
Why Audience Scanning Needs Extra Care
- Crowds move unpredictably, so pre-set distances can be invalidated during the show
- Camera and phone use in the crowd changes exposure conditions
- Scanning effects must be limited in power and speed, not just in direction
- Documentation should show the calculation behind the effect settings
Keep the calculation, the effect settings and the abort procedure in one document so the operator and the safety team work from the same reference.
