Station 64 (White Valley VFD) was dispatched by Westmoreland 911 at 7:11 PM for a Report of an odor of Natural Gas inside Townhomes within Station 64's district. Engine 64 went enroute with (4) firefighters on board and Rescue 64 with (3) firefighters on board. Upon Engine 64's arrival, Assistant Chief 64-1 took Command and crews evacuated occupants from the structure and monitored air levels within the complex. Crews began to get low readings of O2 (Oxygen) and increasing levels of LEL (Lower Explosive Level). Once this was determined, Command 64 requested for Team 800 (Westmoreland County Hazardous Materials Response Team) to be activated. Once Team 800 arrived on scene crews worked with Team 800 along with mutual companies to determine the cause of the odor. Crews then ventilated the structure by setting up fans in front and behind each residence. Chief 64 then arrived on scene shortly after and assumed Command from Assistant Chief 64-1. Once the odor was cleared from the area and air monitoring was checked and numbers started to go back to normal, Command 64 began to release all apparatuses and crews from the scene and returned them back in service.
