The mark consists of a green, three-dimensional house with a darker green on the left side to show the three-dimensional aspect of it. Above the house is a curved, blue, three-dimensional arrow going from left to right, with a darker blue at the tail end. Below the house is a curved, red, three-dimensional arrow going from right to left, with a lighter red at the tail end. The red arrow overlaps a very small amount of the left corner of the house. Below the red arrow is a shaded, gray, oval shadow. To the right of the house, arrows, and shadow is the word "SAFE" in black, block, all capital letters. Underneath the house, arrows, shadow and the word "SAFE" are the words "SMOKE" "AIR" "FIRST PRIORITY" and "EMERGENCY SERVICE" in smaller black, block, all capital letters with a straight, vertical, black line separating each quoted word or phrase. The color white in the mark represents background, outlining, shading and/or transparent areas and is not claimed as a feature of the mark.
