National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Safe Decompression Schedules for Caisson Workers.

PB85103612

Publication Date	1983
Personal Author	Kindwall, E. P.; Edel, P. O.; Melton, H. E.
Page Count	128
Abstract	A 3 year program designed to evaluate new decompression tables for compressed air workers is described. Development of tables from commercial diving data is reviewed, along with the general considerations and procedures used to compare these and OSHA tables using human subjects. Specific methods are described for whole body nitrogen washout studies and ultrasonic bubble detection experiments. The authors conclude that little difference exists between the decompression schedules given by these decompression tables and OSHA tables; however, the decompression tables are significantly better than the OSHA tables since they combine the use of oxygen and stage decompression which have synergistic effects in increasing nitrogen elimination during decompression. The schedules may be difficult to implement because of added equipment costs and the need to retain caisson crews.
