Fire engines have advanced throughout the last four centuries to help protect the land and citizens of this nation. The first fire engines were human propelled water pumps with no room for personnel. Around the end of the 1800s, the threat of fire within densely populated areas brought about paid firefighters equipped with horses to pull the early apparatus. The modern day fire engine emerged in the 1960s armed with water pumps, a reservoir, and enclosed seats for the crew. As the threats of fire began to change, so did the specialization of the fire engine on scene. In its most basic form, fire engines are equipped with hoses, water, equipment, and personnel that can aggressively fight the fire. Let’s take a look at how the National Fire Protection Association (NFPA) Standard 1901, Standard for Automotive Fire Apparatus classifies the vehicles by type and function.
