A Front Range fire chief and former firefighter has died from a rare form of cancer that’s believed to be job-related. Troy Jackson worked with South Metro Fire Rescue for nearly 30 years. He passed away today after a six-year cancer battle. Doctors diagnosed Jackson with adenoid cystic carcinoma in 2013. Since then, the department has instituted new safety measures. “After the diagnosis and we found out it was a job-related cancer, we started looking at our hygiene habits and cleaning off our bunker gear,” assistant chief of operations Jon Adams said. “We just became a lot more aggressive and more informed about the carcinogens and the danger associated with our firefighting.” Jackson joined South Metro Fire as a firefighter in 1990 and worked his way up to become assistant chief of operations in 2016. He stepped down in August because of his advancing cancer.
