  • Patent number: 4553633
    Abstract: A safety harness for workers employed in confined space work such as entry to manholes is derived from a mountaineer's harness enhanced to provide improved functionality in this specialized application. Additional neck and crotch straps decrease the hazards involved to a topside worker in protecting a descending worker entering a confined space, and facilitate extraction of the descending work from the space in the event of an emergency. The harness incorporates fluorescent striping visible regardless of the position of a worker thus eliminating the need for a separate safety vest, and the addition of a pulley reduces the effort required to extract the descending worker from a confined space in an emergency.
