In an example, a system for preventing a flip door from being raised without a guardrail installed is disclosed. The system includes a guardrail having a post, and the post having a post dog. The system also includes a safety latch mechanism configured to be coupled to a fixed structure. The safety latch mechanism includes a body, a socket disposed in the body and configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to retain a flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.

There is provided a railing post adaptor for a roof support apparatus. The roof support apparatus comprises an elongate member having a plurality of longitudinal sides. The railing post adaptor comprises a roof support apparatus connector for securing the railing post adaptor to the roof support apparatus. The roof support apparatus connector comprises a first connection portion arranged to engage, in use, with a first set of the plurality of longitudinal sides, and a second connection portion, movably mounted to the first connection portion and arranged to engage, in use, with a second set of the plurality of longitudinal sides, the second set being different from the first set. The roof support apparatus connector further comprises a railing connection portion extending from the roof support apparatus connector for detachably securing a proximal end of a railing post to the roof support apparatus via the railing post adaptor. The first set and the second set each comprise at least two longitudinal sides. The first connection portion and the second connection portion are together configured to substantially prevent rotation of the railing post adapter about a longitudinal axis of the elongate member by engagement with the first set and second set of longitudinal sides.

A method and apparatus for assembling a hanging scaffold system within the aft pressure bulkhead area of an aircraft to provide access to the pressure dome without contacting the pressure dome. The hanging scaffold system comprises a group of horizontal supports to support at least one floorboard. A group of vertical supports is connected to and extends perpendicularly from the group of horizontal supports. A clamping device is attached to each vertical support of the group of vertical supports and further engages an attachment point on an internal structure of an aircraft.

A rapid release and rapid install latching member for use with ladder cages to couple the cage rings is provided wherein the latching members are capable of retaining the cage ring connecting members thereon without the use of external fasteners. The latching members are designed such that they may be removed from or installed on the ladder cage while the ladder cage is installed at the work site or otherwise for quick and easy repair or replacement. An exemplary ladder cage contains a plurality of ring members having a plurality of latching members interspaced around the circumference thereof, with adjacent ring members being coupled to each other through the interaction of cage ring connecting members with the latching members.

A holder for holding an object on a formwork panel, in particular for holding a railing component on a ceiling formwork panel, wherein the holder is configured for being affixed to the formwork panel, and the formwork panel has two longitudinal edge supports and two transverse edge supports, wherein the holder has a first arm that is configured for engaging with a longitudinal edge support of the formwork panel and a second arm that extends transverse to the first arm, forms an angle space together with the first arm, and is configured for engaging with a transverse edge support, wherein the first arm has a first projection for being introduced into an opening of the longitudinal edge support on its side facing the angle space, and the second arm has a second projection for being introduced into an opening of the transverse edge support on its side facing the angle space.
