The objective of this effort was to implement the Phase I test plan for characterizing occupational exposures of crew members on bulk liquid tankers to chemical substances, primarily cargo vapors. Additional chemical substances included nuisance dust, asbestos fibers, oil mist and silica dust. This report documents the measurement and monitoring data that were collected on six at-sea voyages that involved tankers carrying Subchapter O, Subchapter D and unregulated liquid products. The interpretation of these occupational exposures was based on a conservative method that makes use of the medical monitoring response level concept and current values of the ACGIH TLVs. This method was developed because the work routine that forms the basis for TLVs is not generally applicable to marine operations. Noise dosimetry was performed on two voyages in order to characterize the environment in an Engine Room and in the Deck Department of a state-of-the-art product tanker. This study concluded that the potential for unacceptable inhalation exposures is greatest during open tank gauging and entry into product tanks. Volume II, Part A represents the body of the final report. The detailed voyage reports are contained in Part B.
