Embodiments of the Lighted Ladder are comprised of a ladder; a plastic housing; one or more LED strip lighting; a cordless battery mounting means; a battery; a controller housing; a control interface; power wiring; potentiometer wiring; and motion sensor wiring. The ladder is weight-balanced by placement of the battery mounting means, the battery, and controller housing in a low position on the ladder. The battery mounting means is designed to accept a cordless tool battery. The battery mounting means is designed to accept a commercially available battery of at least 12V and at least 3.0 Ah. One plastic housing is located on each of the vertical front rails. Each LED strip lighting can illuminate an angular range of 120 degrees (120°) creating a total illumination range of 300 degrees (300°).

A fire exit system is disclosed. In one particular embodiment, the fire exit system may include a motor mechanically coupled to a window such that the motor, when turned on, causes the window to open, a controller coupled to the motor, and a switch coupled to the controller. When the switch is activated, the controller is configured to turn on the motor to open the window.

An unmanned aerial vehicle (UAV) or manned/unmanned personal flying device (PFD) may be used to deliver a deployable descent system to an elevated location at which people await rescue, such as people trapped in an upper story of a burning building. The UAV or PFD may be used to deliver the descent system, attach the descent system to the building, and deploy the descent system. After deployment, the descent system may be tensioned to prevent sway and facilitate descent. Standoffs may be installed or integrated into the descent system to provide for adequate handholds for descending individuals. Various equipment and methods used in such systems are described herein.

Systems and methods for providing access for workers to cell towers are disclosed. The system is useful on stealth cellular towers that do not have external ladders or climbing pegs for aesthetic reasons. The system may include a channel (e.g., a track) that may be permanently mounted to the cell tower and extends from a bottom of the cell tower to a top of the cell tower as well as a track-line (e.g., a chain, a belt, etc.) located within the channel such that the track-line acts as a loop running from the bottom of the cell tower to the top of the cell tower, and vice versa. A modular ladder with climbing pegs may be attached to the track-line and inserted into the channel such that the modular ladder may be pulled up the channel to the top of the cell tower by the track-line and then secured.

An attic ladder modification kit, a method of modifying an attic ladder using the kit, an attic ladder, and a method of using the attic ladder. The attic ladder modification kit includes a plurality of components for installation onto the attic ladder to improve the safety and ease of use of the attic ladder through modification, either during construction of the attic ladder, or as an after-market addition to the attic ladder. The plurality of components includes a pair of springs to bias a hinged connection between a middle section and an upper section of the attic ladder, means to removably secure a lower section hingedly connected to the middle section of the attic ladder, and a rope and pulley system and a descent rope to facilitate raising and lowering the attic ladder into and out of an attic opening, respectively.

A window frame assembly incorporating a structure for containing an emergency ladder, the ladder contained within a compartment in the lower portion of the window frame assembly. The ladder is connected directly to the structure of a building by a structural attachment, the structural attachment having connection points so that the weight of a user of the ladder is supported by the building structure. The compartment opens into the living or working area of a building, and has a removable cover. The window assembly is installed as a unit once the structural attachment is affixed to a building structural member in the bottom of the framed window opening.
