What to look for

The terrorist threat is serious and ongoing. Members of the public can help to prevent terrorism by being alert to possible suspicious activities. Terrorists have to live somewhere, and they need to plan and prepare for attacks. They buy and store materials, fund their activities, move around, prepare equipment and weapons and possibly undergo training. They may have people helping them - and these people might come and go at strange times of the day and night.

Emergency planning

Emergencies cover a wide range of situations. This includes not just man-made events such as terrorist attacks but also natural and accidental events such as foot and mouth outbreaks, industrial accidents and flooding. Responding to emergencies is usually the task of a number of agencies, including local authorities. In most instances, the police or one of the other emergency services will lead the response.
