On-Site Evaluation of Field-Based Procedures for Screening Diver's Air
Abstract
We previously developed a set of procedures using three portable analyzers for screening diver's air on-site according to current specifications in the U.S. Navy Diving Manual. This report evaluates these procedures under actual sampling conditions in the field to allow a decision about possible transition to the Fleet. This field test consisted of using the NEDU procedures to screen the output air from two compressors at each of two on-shore sites at pre-scheduled tines during a one-year evaluation. The purpose of the field test was to evaluate the screening procedures at operational sites in terns of (1) variability of measurements, both short-term and within the day, (2) accuracy of the measurements, (3) reliability of test equipment, (4) need for any changes to the procedures, and (5) ability to train on-site personnel. Although the U.S. Navy has no official performance requirements for screening diver's air in the field, these procedures, as evaluated first in the laboratory and now during this one-year field test, should meet the need for reliable field screening.
