A fire and disaster evacuation apparatus installed in a high-rise building includes a stationary frame; a front plate; a side plate; a bottom; a locking device; and a lever part, and its width is less than a thickness of an outer wall of the building. The apparatus can be mounted integrally with an outer wall of an apartment or a building and thus it can be mounted without changing the exterior of the building. The apparatus is formed in a thin structure so that it can be mounted at any place as long as an outer wall is 160 mm or more, and is located inside a wall body so that it does not affect the exterior of the building, and so that additional power is not necessary to drive the apparatus.

An access deck assembly is provided for an aerial lift vehicle mobile platform. A base member defines an upper surface to support an operator, and has first and second guides to cooperate with the platform. A locking mechanism is supported by the base member and retains the access deck to the platform. A method of connecting an access deck assembly to a mobile platform is provided. The access deck assembly is positioned relative to the platform to be above and spaced apart from the platform floor surface, with the base member of the access deck assembly substantially within a perimeter frame of the platform. An access deck assembly has a guide member connected to a base member and configured to connect the base member to the mobile platform and support the base member directly above and spaced apart from the platform floor surface.

A system is provided for safe access to a roof through an opening in a roof of a structure having a fixed ladder leading upward to the opening. The system includes a mechanism to drive a set of pushrods to raise a hatch covering the opening. The system may include a section of ladder secured to the underside of the hatch. The system may have an extendable ladder driven by the drive mechanism to slide along the fixed ladder and extend through the opening in the roof when the hatch is raised. The system may include a safety pole driven by the drive mechanism to extend through the opening in the roof when the hatch is raised. The system allows someone who needs to access the roof for inspection or maintenance to safely open the hatch, climb up through the opening in the roof, and safely step onto the roof.

A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.

A fire and disaster evacuation apparatus installed in a high-rise building, including a stationary frame; a front plate; a side plate; a bottom; a locking device; and a lever part, and its width is less than a thickness of an outer wall of the building. The fire and disaster evacuation apparatus has the effects that a resident stranded by a fire or a disaster in a building such as a high-rise building is able to safely and easily evacuate and escape to a lower floor by easily operating the apparatus, that the apparatus can be mounted integrally with an outer wall of an apartment or a building and thus it can be mounted without changing the exterior of the building, that the apparatus is lightweight and thus secures stability, that the apparatus is formed in a thin structure so that it can be mounted at any place as long as an outer wall is 160 mm or more, that the apparatus is located inside a wall body and thus it does not affect the exterior of the building, and that additional power is not necessary to drive the apparatus.
