Evacuate
When caught up in such a situation, the first thing to do is to escape the scene as quickly as possible, according to articles on security. Thus, always be aware of your surroundings and look out for places you could take cover behind or run to in case of an attack. When in public places, malls or offices, look out for emergency exits. If you can’t escape an attack, you can find the nearest hiding place and lie – where you can be safe from any gunshots or being seen by the attacker. If you are in a room, turn out the lights, lock the door and block it with furniture. Anti-terror experts, Liam McDaid and Gaz Rowley, recommend creating a barricade against the door or putting a wedge under the door to stop the assailant getting in. Meanwhile, your phone should be on silent as you communicate with the police, friends and families about the situation via text. Others reveal their hideouts on social media though some experts say it is not advisable as attackers can track this.
