APPARATUS FOR ESCAPING AREA OF ACCIDENT

摘要

An apparatus for escaping the area of an accident on a drilling rig platform or the like is disclosed. Emergency escape from the platform is along a path defined by at least one cable extending between the platform and a remote, terminal location. The apparatus includes a frame in which a top of the frame is located above a bottom of the frame when the frame is erect. The frame defines an interior space sized to accommodate a worker. A locking system includes a locking mechanism and also a foot-actuated disengager that is located at least proximate to the bottom of the frame. The locking mechanism is adapted to interlock with a mating portion on the platform to prevent the frame from travel away from the platform when the locking mechanism engages the mating portion. The disengager is connected to the locking mechanism and has a foot receiving surface region upon which force can be applied to displace the disengager between a first, engaged position and a second position to disengage the locking mechanism from the mating portion. The frame will travel away from the platform to the terminal location under gravity when the locking mechanism is disengaged.
