In plain language
You can skip hiring visual observers/assistants if you set up physical barriers like fences, cones, or warning signs to completely block people from entering your flight area.
Requirement as structured
JCAB states that operators may replace the deployment of safety assistants by clearly marking an entry control zone with fences, walls, warning signs, or cones to prevent third parties from entering the flight area.
