What's Coming Down the Road. Unlike understanding human anatomy, understanding the anatomy of safety improvements is a never-ending process. Safety features vary widely from year to year in their design and placement among makes and models. While the information illustrated here is aimed at raising awareness and assisting rescuers, your department's SOPs should remain the sole guiding force in rescue operations. Count on Holmatro, though, to provide the information and next-generation rescue tools needed for whatever's coming down the road.
