| The government has unveiled a 22 page terror advice pamphlet to help the public prepare for an attack and other emergencies. BBC News Online outlines the key points of the document.
AT HOME Gather bottled water, tinned food and a bottle/tin opener.  | ASK THE EXPERT Put your questions to Mike Granatt, former head of the Civil Contingent Secretariat in a LIVE interactive forum at 1500 BST | Keep a list of useful phone numbers such as your doctor's and close relatives' and have your mobile phone with you. Gather toiletries, sanitary supplies and regularly prescribed medication. Keep a torch with spare batteries, candles and matches and a radio with spare batteries close by. Tune into the local radio for advice and updates. Keep a first aid kit close by. If there is a major power cut, turn off electrical appliances that may switch on when power is restored.
AT WORK If a bomb goes off at your place of work look for the safest way out. If a bomb goes off outside the building, stay inside away from lifts, windows and outer doors in case there is a second bomb in the area. If you are trapped in debris stay close to a wall, tap on pipes so that rescuers can hear you and do not use lights and matches in case of gas leaks. AT SCHOOL Tune into the local radio for advice from the local council in the event of a major emergency because if your children are at school it may not be safe to collect them. GENERAL In the event of a chemical, biological or radiological attack, move away from the immediate source of danger. Wait for the emergency services to arrive to examine you and if necessary, decontaminate you. Make sure you do not go home untreated because you could contaminate others and make any incident worse. If you are in a public place be vigilant and look out for suspicious behaviour, vehicles or packages and do not hesitate to tell the police. Make sure 999 has been called if people are injured or their life is threatened. Check for injuries and keep calm.
