A Lieutenant, an Engineer, and one Firefighter make up its crew. Within the air conditioned cab the crew of three use headsets to communicate with each other and with the fire dispatch center. The walk through pump operator's panel is located just behind the cab allowing the Engineer easy access to both sides of the engine and a great view to see all that is going on at the emergency scene. Also located at the pump operator's panel is a deluge gun used to shoot up to 1000 gallons per minute of water a great distance. Ladders are stowed away above the hose bed, to the left side of the engine on an arm raised and lowered by hydraulics.
Engineers are very familiar with the area they are responding to.
If for some reason they do not know where a specific address is, there are plenty of maps available to us to help us get to the right location.
