The Government has produced and distributed a booklet called "Preparing for emergencies: what you need to know" . It lets you know what you should do in an emergency. It includes general advice as well as information for specific emergencies. Please read this booklet and keep it somewhere safe. You should also familiarise yourself with any plans or procedures at your workplace in connection with bomb warnings.

This will involve showering in a decontamination unit and dressing in temporary clothing provided by the emergency services. This must take place near to where the incident happened so that other areas are not contaminated.
