The modern fire truck reserves a seat for each personnel with a variety of safety devices including airbags, seat belts and traction control. Many hold 1000+ gallons of water,  a foam system to aid in fighting fire and a large amount of cabinet space for  the variety of everyday and specialty equipment needed to fight fire, extricate patients at a car accident, assist on a medical call, mitigate a hazardous material incident and more.

Shameless self-promotion alert:
If you go to my online shop, I’m selling postcards and posters featuring this firetruck¬†as part of a series.
