Last night around 20:00 hours, 137 Rescue, Engine, and Squad responded into Penn Hills for a working commercial structure fire. EVFD units arrived onscene and went to work assisting with RIT operations and suppression. EVFD personnel would operate on scene for over 9 hours before being released back into service. Unfortunately during the incident, several firefighters from other departments were injured due to the results of an explosion, as well as heat related emergencies. All firefighters are expected to be ok. We wish them a speedy recovery.
