What to do

1. A forgotten item is not automatically a bomb. For visible danger signs or a threat, do not touch it: move away and alert others.
2. Move at least 100 metres from a small item, 200 metres from a car or large item, and 400 metres from a truck. These distances do not guarantee safety. Do not approach to measure them. Follow police instructions.
3. Use solid cover out of sight of the item, away from glass and vehicles.
4. From that distance and out of sight, alert police.
5. No phone or radio near the item. Another suspicious item: do not investigate. Move away and report from distance and out of sight.
6. Unable to move away: alert staff for assisted evacuation. Do not pass beside the item or send anyone to touch it.
