<p>An autonomous gas powered ram comprising a main body (12) having an internal cavity (14) and an actuator (38) mounted in this internal cavity. The actuator is movable in the cavity from a first operative mode to a second operative mode. Movement of the actuator towards the second operative mode is caused by the detonation of an explosive charge located within the cavity. The explosive charge (56) is detonated upon detection of an operation failure, a fire or a hazardous operation condition. The ram also comprises a lock for preventing the actuator from moving to the first operative mode once the explosive charge has detonated.</p> |
