Found on Chicago Fire Department Firefighters Union – Local 2 Facebook page:

The job our members do is dangerous enough, now their health and safety is at risk with old and failing equipment! The conditions of our spare rigs are awful. Literally from falling apart to now catching on fire, all which is preventable. At least in this incident no one was hurt. #local2atwork #cfdprofessionals
