What safety rules apply to audience-scanning laser effects at festivals?

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
