On November 23, 1993, Candidate Firefighter Steven McNamee of the Chicago Fire Department died in the line of duty during a training accident at the Chicago Fire Academy. Candidates had been taught the proper method for jumping from a building into an inflatable Life Cube and were practicing the technique by dropping thirteen feet into the device. Twenty-one candidate firefighters successfully completed the exercise, but McNamee was fatally injured during his jump, even though he landed within the Life Cube.

This ladder truck for the Chicago Fire Department Training Division was dedicated to Steven McNamee on November 23, 2009 in the presence of his wife and son Steven.
