(section 5 of the Act) This is one of the four types of public protection procedure set out in the Act. Invacuation involves moving people away from danger to a place within the premises or event where there is less risk of physical harm being caused to them. This can include bringing people into the premises or event from outside or moving people from one part of the premises or event to another, where it is safe to do so. See paras. 7.39 to 7.40.
