Safety hatch system and egress
First Claim
1. An electronically controlled hatch system for use with an access port for ingress or egress, said hatch system comprising:
- a hatch cooperable with said access port for limiting entry and exit through said access port, wherein said hatch has at least an open position and a closed position;
at least one guide rail mounted adjacent said hatch;
at least one safety rail retractably mounted adjacent said access port and slidably engageable with said guide rail to raise and lower said hatch to the open position and the closed position as said safety rail is retractably raised and lowered above and below the access port;
an actuator cooperable with said safety rail for raising and lowering said safety rail; and
a central control unit operable to communicate with the actuator to position the hatch.

Abstract
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, hazard, security, lighting, and other safety monitoring detectors/apparatuses, and a centralized controller.
