The intent of these regulations is to provide a means to minimize the use of intoxicants by merchant marine personnel and to promote a drug-free and safe work environment.  Enforcement of these regulations by the U. S. Coast Guard is necessary to ensure that marine employers conduct testing when required and in the manner described in the regulations.  The marine employer, aided by a Coast Guard Drug & Alcohol Program Inspector (DAPI), should be able to develop a program that serves as a strong deterrent to the use of intoxicants by covered crewmembers, and promotes a safe, durg-free workplace.
