Abstract: At approximately 1:50 a.m. on November 10, 2011, Employees #1 and #2, both firefighters, were performing an exterior attack on a barn/garage that was fully engulfed in fire when the chimney collapsed. Three neighboring fire companies arrived at the scene and assisted in extinguishing the fire. Employee #1 sustained injuries to his lower back and 4 fractures to his pelvis. Employee #2 was diagnosed with a concussion, fractured left tibia and fibula, multiple broken ribs and also a crushed collar bone, scapula and right shoulder socket. Employee #2 suffered from edema in all extremities and a small pneumothorax, which was treated by administering humidified oxygen. Both Employee #1 and #2 were admitted to the hospital into the Intensive Care Unit.
