The mark consists of stylized characters spelling HOTZONE in a color scheme evocative of flame and consisting of (from the top of each character to the bottom of each character) the color yellow graduating into the color orange graduating into the color red. The characters spelling HOTZONE are emblazoned atop a diamond shaped emblem with black borders that contain four distinct elements across each of the four segments of the diamond: on top, a waving red, white and blue flag across a red background; to the left, a white shield bearing the words "Police Department" on a navy blue background; to the right, an emergency medical symbol featuring a white staff of Aesculapius with a single white snake wrapped around the staff on a navy blue Star of Life against a gold background; and on bottom a black and white figure of an adult male wearing a hazardous materials suit, helmet, white gloves and white boots set against a white background.
