There is provided an emergency actuation device (1) for opening a door (70), the emergency actuation device comprising:at least one pressurised gas supply (2); an actuator (30) including: an actuator chamber (32), an actuator piston (34) moveable between a retracted position and a fully extended position to open the door (70), a vent (38) for venting the actuator chamber (32) when the actuator piston (34) is in its extended position. The emergency actuation device further comprising a percussion device (10) including a percussion piston (14) moveable on activation of the percussion device between: a storage position in which the pressurised gas supply (2) is isolated from the actuator (30) and an activated position in which the pressurised gas supply (2) is coupled to the actuator (30). The actuator (30) is coupled to the percussion device; and the actuator (30) is configured such that movement of the actuator piston (34) towards its activated position resets the percussion piston.
