• Establish exclusion zones based on the demolition method, height, and collapse radius.
• Install physical barriers at the exclusion zone boundary using fencing, blocks, or hoarding.
• Post warning signs at all entry points stating demolition is in progress.
• Control access with a banksman or marshal at every active entry point.
• Extend the zone to protect public footpaths, roads, and neighbouring properties.
• Install overhead protection where debris could fall onto public access routes.
• Review and adjust the exclusion zone as demolition progresses and conditions change.
• Ensure emergency vehicle access routes are planned and maintained throughout.
• Brief all site workers on the exclusion zone boundaries before demolition begins.
• Monitor the exclusion zone continuously for unauthorised entry during active demolition.

• DON'T set exclusion zones without considering the demolition method and collapse radius.
• DON'T rely on tape alone — use substantial physical barriers to define the zone.
• DON'T allow gaps in signage — every entry point must be clearly marked.
• DON'T permit uncontrolled access — a marshal must manage every active entry point.
• DON'T forget public protection — footpaths and roads may need closures or diversions.
• DON'T omit overhead protection where falling debris could reach public areas.
• DON'T keep the same zone throughout — adjust it as the demolition sequence progresses.
• DON'T block emergency access routes with barriers, plant, or demolition debris.
• DON'T assume workers know the boundaries — brief everyone before each phase begins.
• DON'T enter the exclusion zone without authorisation and the correct PPE for demolition.
