ABSTRACT There is provided an emergency actuation device for opening a door, the emergency actuation device comprising: at least one pressurised gas supply; an actuator including: an actuator, chamber, an actuator piston moveable between a retracted position and a fully extended position to open the door, a vent for venting the actuator chamber when the actuator piston is in its extended position. The emergency actuation device further comprising a percussion device including a percussion piston moveable on activation of the percussion device between: a storage position in which the pressurised gas supply is isolated from the actuator and an activated position in which the pressurised gas supply is coupled to the actuator. The actuator is coupled to the percussion device; and the actuator is configured such that movement of the actuator piston towards its activated position resets the percussion piston.
