A Study To Determine The Feasibility For Developing Interim Decompression Schedules For Tunnel Workers.
NIOSH 1979 Sep:12 pages
The development of interim decompression tables for tunnel workers in hyperbaric atmospheres was described. The impetus for developing new tables stemmed from a 25 percent incidence of disabling dysbaric osteonecrosis among compressed air workers in Milwaukee, Wisconsin, who had used the OSHA decompression tables at pressures greater than 36 pounds per square inch. It was felt that a new set of decompression schedules was essential to reduce the incidence of dysbaric osteonecrosis and decompression sickness among compressed air construction workers. Since production and testing a new set of tables would take at least 2, new interim tables were suggested. A workshop sponsored by the Undersea Medical Society proposed a new set of decompression schedules. Features of the suggested interim tables included: schedules being calculated for 2 pounds per square inch gauge pressure increments from 14 to 50, exposures ranging from value, and the schedules being calculated for use at sea level and a tunnel temperature of 60 degrees-F. Tables for both oxygen and air decompression were to be produced.
