Marine Safety Insignia
The Marine Safety Insignia is awarded to enlisted members (grade E-4 and above) and officers of the United States Coast Guard and United States Coast Guard Reserve, to Coast Guard Civilians, and to members of the United States Coast Guard Auxiliary to recognize professional accomplishment in the Marine Safety program. In addition, the United States Coast Guard Auxiliary has a similar award called the Auxiliary Marine Safety (Trident) Device as part of the Auxiliary's Marine Safety Trident Program.
Admiral James Loy, as Commandant of the Coast Guard, approved the creation of the Marine Safety Insignia on November 2, 2000 to recognize the professional accomplishment of personnel in the Coast Guard's Marine Safety Program. The Commandant presented Rear Admiral Robert C. North, then-Assistant Commandant for Marine Safety and Environmental Protection, with the first Marine Safety Insignia on April 10, 2001, who accepted it "on behalf of all the marine safety professionals past, present, and future." Admiral North then presented the second Marine Safety Insignia to Master Chief Bell, the Marine Science Technician Rating Force Manager.
On the original Insignia criteria information sheet, the description and symbolism of the Marine Safety Insignia is explained:
|“||The Marine Safety Insignia is a gold rectangle with a trident extending within its length. A gold compass rose is centered above the trident with a silver shield covering the center of the compass rose. A braided rope runs the length of the trident and is intertwined with the compass rose.
To receive the Marine Safety Insignia the member must earn four marine safety competencies. To earn the permanent version of the insignia, the member must also serve a cumulative five years at marine safety field units. The list of marine safety competencies and definition of a "marine safety field unit" is detailed on the Coast Guard's CG Portal intranet webpage.
Temporary entitlement may be issued by the commanding officer of a marine safety field unit to a member who has received four marine safety competencies and completed the marine safety initial indoctrination training program but who has not been assigned to a marine safety field unit for at least five years. The temporary entitlement is for the period that the member is permanently assigned to that unit.
Insignia guidance and references 
The first detailed information on the Marine Safety Insignia was announced in ALCOAST 183/01. More guidance was included in ALCOAST 295/01. Updated guidance was announced in ALCOAST 192/10, which changed the marine safety field unit service requirement for permanent award from four years to five, and updated the criteria to reflect modified qualification codes and the adoption of the Sector organizational structure.
Policy regarding the Marine Safety Insignia is found in Chapter 4.B.4 of the Coast Guard Enlisted and Officer Accessions, Evaluations, and Advancements Manuals. The insignia must be worn in accordance with Chapter 3.E.1 of the Uniform Regulations Manual.
