PART 4_MARINE CASUALTIES AND INVESTIGATIONS--Table of Contents
 
    Subpart 4.06_Mandatory Chemical Testing Following Serious Marine 
            Incidents Involving Vessels in Commercial Service
 
Sec. 4.06-50  Specimen analysis and follow-up procedures.

    (a) Each laboratory will provide prompt analysis of specimens 
collected under this subpart, consistent with the need to develop all 
relevant information and to produce a complete analysis report.
    (b) Reports shall be sent to the Medical Review Officer meeting the 
requirements of 49 CFR 40.121, as designated by the marine employer 
submitting the specimen for testing. Wherever a urinalysis report 
indicates the presence of a dangerous drug or drug metabolite, the 
Medical Review Officer shall review the report as required by 49 CFR 
part 40, subpart G, and submit his or her findings to the marine 
employer. Blood test reports indicating the presence of alcohol shall be 
similarly reviewed to determine if there is a legitimate medical 
explanation.
    (c) Analysis results which indicate the presence of alcohol, 
dangerous drugs, or drug metabolites shall not be construed by 
themselves as constituting a finding that use of drugs or alcohol was 
the probable cause of a serious marine incident.
