Specifications include, but are not limited to: A firm to build a Confined Space Training Unit. The intent of this unit is to provide confined space training without having to place firefighters in actual confined spaces. Training in real confined spaces being too dangerous and too hard on protective equipment, we intend to build a prop that closely resembles the challenges of confined spaces while maintaining a safe environment. With the weather conditions in Kansas swinging from single digits in the winter and exceeding 100 degrees (with high humidity) in the summer, we included a HVAC (Heating, Ventilation, Air Conditioning) system in our concept. We will use the HVAC system to keep the temperatures in the trailer in the 75 to 85 degree range in the summer and above 40 in the winter.
