A practice started last year as a practical way to further protect firefighter from the carcinogens that may get tracked into fire trucks from turnout gear is underway once again in Bethel.  Stony Hill Volunteer Fire Company says SERVPRO of Danbury/Ridgefield was at the firehouse this week to do an annual deep clean of apparatus interiors.  January is Firefighter Cancer Awareness Month.  A National Institute for Occupational Safety and Health study found that firefighters face a 9% higher risk of cancer than the general public and a 14% higher chance of dying from cancer.
