Safer work starts with better knowledge.

Obtain appropriate structural and hazardous material information before demolition.

Follow the approved demolition sequence and temporary support design.

Stop when hidden conditions differ from the survey.

Keep unauthorised people outside the demolition danger area.

Recognise that removing one element can affect another.

Do not alter props or bracing without engineering approval.

Confirm utility disconnection arrangements before structural disturbance.

Plan dust control appropriate to the materials being disturbed.

Stop disturbing suspect materials and seek competent assessment.

Avoid accumulating demolition debris beyond approved floor loading.

Keep clear of unsupported walls and partially demolished sections.

Consider adjoining properties, pavements and occupied areas.

Use equipment suited to the planned demolition method.

Control openings and edges created as work progresses.

Assess demolition noise before work and protect affected workers.

Maintain access for emergency services as the site changes.

Document remaining instability and restrictions between shifts.
