employed on board a vessel are fully indoctrinated in the requirements 
of this subpart, and that appropriate vessel personnel are trained as 
necessary in the practical applications of these requirements.
    (f) Each marine employer shall implement the testing requirements of 
this subpart in accordance with the implementation schedule provided in 
46 CFR 16.205 and 16.207. (Note: 46 USC 2115: The maximum civil penalty
for failure to comply with the drug and alcohol testing requirements has been

Sec. 4.06-5  Responsibilities of individuals directly involved in 
          serious marine incidents.

    (a) Any individual engaged or employed on board a vessel who is 
determined to be directly involved in a serious marine incident shall 
provide blood, breath or urine specimens for chemical tests required by 
Sec. 4.06-10 when directed to do so by the marine employer or a law 
enforcement officer.
    (b) If the individual refuses to provide blood, breath or urine 
specimens, this refusal shall be noted on Form CG-2692B and in the 
vessel's official log book, if one is required.
    (c) No individual may be forcibly compelled to provide specimens for 
chemical tests required by this part; however, refusal is considered a 
violation of regulation and could subject the individual to suspension 
and revocation proceedings under part 5 of this chapter and removal from
any duties which directly affect the safety of the vessel's navigation
or operations.

Sec. 4.06-10  Required specimens.

    Each individual required to submit to chemical testing shall, as 
soon as practicable, provide the following specimens for chemical testing:
    (a) Urine specimens, collected in accordance with Sec. 4.06-20 and 
part 16 of this chapter.
    (b) Blood or breath specimens, or both, collected in accordance with 
Sec. 4.06-20. (Note: Alcohol testing for crewmembers or other persons responsible
for the operation or other safety sensitive functions of the vessel or vessels 
involved in such casualty is conducted no later than two hours after the casualty 
occurs, unless such testing cannot be completed within that time due to safety 
concerns directly related to the casualty.)

Sec. 4.06-20  Specimen collection requirements.

    (a) All inspected vessels certificated for unrestricted ocean 
routes, and all inspected vessels certificated for restricted overseas 
routes, are required to have on board at all times a breath testing 
device capable of determining the presence of alcohol in a person's 
system. The breath testing device shall be used in accordance with 
procedures specified by the manufacturer.
    (b) The marine employer shall ensure that urine specimen collection 
and shipping kits meeting the requirements of Sec. 16.330 of this part 
are readily available for use following serious marine incidents. The 
specimen collection and shipping kits need not be maintained aboard each 
vessel if they can otherwise be readily obtained within 24 hours from 
the time of the occurrence of the serious marine incident.
    (c) The marine employer shall ensure that specimens required by 
Sec. 4.06-10 are collected as soon as practicable following the 
occurrence of a serious marine incident.
    (d) When obtaining blood, breath, and urine specimens, the marine 
employer shall ensure that the collection process is supervised by 
either qualified collection personnel, the marine employer, a law 
enforcement officer, or the marine employer's representative.
    (e) Chemical tests of an individual's breath for the presence of 
alcohol using a breath testing device may be conducted by any individual 
trained to conduct such tests. Blood specimens shall be taken only by 
qualified medical personnel.

Sec. 4.06-30  Specimen collection in incidents involving fatalities.

    (a) When an individual engaged or employed on board a vessel dies as 
a result of a serious marine incident, blood and urine specimens must be 
obtained from the remains of the individual for chemical testing, if 
practicable to do so. The marine employer shall notify the appropriate 
local authority, such as the coroner or medical examiner, as soon as 
possible, of the fatality and of the requirements of this subpart. The 
marine employer shall provide the specimen collection and shipping kit 
and request that the local authority assist in obtaining the necessary 
specimens. When the custodian of the remains is a person other than the 
local authority, the marine employer shall request the custodian to 
cooperate in obtaining the specimens required under this part.
    (b) If the local authority or custodian of the remains declines to 
cooperate in obtaining the necessary specimens, the marine employer 
shall provide an explanation of the circumstances on Form CG-2692B 
(Report of Required Chemical Drug and Alcohol Testing Following a 
Serious Marine Incident).

Sec. 4.06-40  Specimen handling and shipping.

    (a) The marine employer shall ensure that blood specimens collected 
in accordance with Secs. 4.06-20 and 4.06-30 are promptly shipped to a 
testing laboratory qualified to conduct tests on such specimens. A 
proper chain of custody must be maintained for each specimen from the 
time of collection through the authorized disposition of the specimen. 
Blood specimens must be shipped to the laboratory in a cooled condition 
by any means adequate to ensure delivery within twenty-four (24) hours 
of receipt by the carrier.
    (b) The marine employer shall ensure that the urine specimen 
collection procedures of Sec. 16.310 of this part and the chain of 
custody requirements of Sec. 16.320 are complied with. The marine 
employer shall ensure that urine specimens required by Secs. 4.06-20 and 
4. 06-30 are promptly shipped to a laboratory complying with the requirements
of 49 CFR part 40. Urine specimens must be shipped by an expeditious means, 
but need not be shipped in a cooled condition for overnight delivery.

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 40.33, 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 
40.33 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.

identified as being directly involved in a serious marine incident, the 
marine employer shall complete Form CG-2692B (Report of Required 
Chemical Drug and Alcohol Testing Following a Serious Marine Incident).
    (b) When the serious marine incident requires the submission of Form 
CG-2692 (Report of Marine Casualty, Injury or Death) to the Coast Guard 
in accordance with Sec. 4.05-10, the report required by paragraph (a) of 
this section shall be appended to Form CG-2692.
    (c) In incidents involving discharges of oil or hazardous substances 
as described in Sec. 4.03-2 (b) and (c) of this part, when Form CG-2692 
is not required to be submitted, the report required by paragraph (a) of 
this section shall be submitted to the Coast Guard Officer in Charge, 
Marine Inspection, having jurisdiction over the location where the 
discharge occurred or nearest the port of first arrival following the 
discharge.

employer shall submit a copy of the test results for each person listed 
on the CG-2692B to the Coast Guard Officer in Charge, Marine Inspection 
to whom the CG-2692B was submitted.

casualties may be made;
    (3) Whether there is evidence that any act of misconduct, 
inattention to duty, negligence or willful violation of the law on the
