The largest fire department in McHenry County Division 5 is the McHenry Township FIre Protection District. With over 150 part-time firefighters running out of four stations, this department responded to 4,369 calls for service in 2009 in a district that is roughly 56 square miles. Their fleet of suppression equipment is 99% Pierce with the one exception being a 1986 S&S tanker running out of Station 2. The newest additions are a pair of twin 2009 Pierce Velocity engines and a 2010 Ford F350/Medtec Type I ambulance. Prior to the purchase of these Velocity units, all McHenry Township engines were on Pierce Lance chassis. They have two squad units; one Pierce Arrow and one Pierce Saber.
