Obverse Design Badge is shaped like a shield, with some leafy branches along the bottom edge making the bottom wider than the top. The top edge is decorative and has four rounded protusions. The center has the badge number of "204" and above it a design of a fire hat on top of a bugle crossed with an old straight tip nozzle. Above the fire hat design is a curved banner that reads "CANAL ZONE". Below the badge number is another banner which reads "VOLUNTEER FIREMAN". The badge has a textured background. Overall the design is similar to the BG-10 and BG-15 police badges.
