An apparatus for use with a manhole and a cable, and a method thereof, is provided. The apparatus comprises a frame having an opening and a coupling mechanism for releasably securing the frame about the manhole such that the opening communicates with the manhole. The apparatus also includes a bearing secured to the frame adjacent the opening, the bearing having a surface over which a cable may travel in a manner that reduces wear on the cable when the cable is fed into or drawn through the opening in the hole.

A manhole assembly including a base, riser, and cap. The base having an upper surface forming a bench, a bottom surface, and a radially outward surface with penetrations there through; and a radial spigot in the radially outward upper edge of the base. The base having a corrosive-resistant layer covering the channels, bench, and radial spigot. Also disclosed is a riser comprised of a corrosive-resistant polymer pipe having a radially outward surface, an inner surface and a bottom surface in contact with, supported by, and sealed to the radial spigot. The cap having a radial spigot, and access hole; the radial spigot in the radially outward bottom edge of the cap resting upon and sealed to an upper edge of the riser. The radially outward surface of the cap and base are aligned with the radially outward surface of the riser.

In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

Embodiments of a manhole cover safety apparatus having a circular base defining a central opening and a flange that extends outwardly from the circular base. An expandable cover is in rotatable engagement with the flange through a plurality of frame members that are secured to a cover portion which is operable between a deployed position wherein the cover portion covers at least a portion of the circular opening to provide a visual and physical warning of an uncovered manhole and a retracted position wherein the cover portion does not cover the central opening.

A manhole assembly including a base, riser, and cap. The base having an upper surface forming a bench, a bottom surface, and a radially outward surface with penetrations there through; and a radial spigot in the radially outward upper edge of the base. The base having a corrosive-resistant layer covering the channels, bench, and radial spigot. Also disclosed is a riser comprised of a corrosive-resistant polymer pipe having a radially outward surface, an inner surface and a bottom surface in contact with, supported by, and sealed to the radial spigot. The cap having a radial spigot, and access hole; the radial spigot in the radially outward bottom edge of the cap resting upon and sealed to an upper edge of the riser. The radially outward surface of the cap and base are aligned with the radially outward surface of the riser.

A safety rail protection system disclosed herein is adaptable to be positioned adjacent to a portal. The system may include a hinged gate having an opening and first and second opposing members, with the hinged gate being operable to open from a closed position to an open position. A first side rail may be present, and may include a first side gate projection extending at least partially into the hinged gate opening, with the first side rail interfacing with at least one of the first and second opposing members when the hinged gate is in the closed position. A second side rail may be present, and may include a second side gate projection extending at least partially into the hinged gate opening when the hinged gate is in the closed position.

A safety landing may include a first support panel positionable within the shaft and having a first support surface and a second support surface spaced apart from the first support surface. At least a first platform may have a first end that is movably connected to the first support panel and a second end spaced apart from the first end. The first platform may have an upper surface, an opposing lower surface and an end surface at the first end. The first platform may be movably between a closed position in which the first platform extends laterally across the shaft, and in which the lower surface rests on the first support surface and an open position in which the first platform is generally upright and the end surface of the first platform rests on the second support surface.

An underground storage vault having a hatch affixed to a hatchway. The underfloor storage vault may be incorporated into a larger structure such that the surface of the vault's hatch may be flush with the surrounding floor, allowing for the hatch to be easily concealed. Once the concealment has been removed, fasteners can be undone so that the hatch can be removed from inhibiting access to the hatchway. Valuables and possessions can be stored in the vaults storage compartment and safely secured by re-affixing the hatch to the vault's hatchway.

Disclosed is a variable sliding manhole safety guard including an installation support part that is installed on an inner wall of a manhole to be installed and has a rail structure vertically extending by a predetermined length and configured to change a vertical position of a movement guide, the movement guide that is mounted on the rail structure to change a vertical position, has a structure vertically extending by a predetermined height, and is mounted on a safety fence in an integrated structure, the safety fence which is mounted on the movement guide in an integrated structure and includes a plurality of frames forming a cylindrical structure having an outer diameter corresponding to an inner diameter of a manhole entrance, and in which an openable entrance door is installed in an upper one surface thereof.
