Dallas Fire-Rescue crews used specialized firefighting foam to battle a major fire at an Oncor electrical substation early Sunday morning, according to reporting by Fox 4.
Firefighters were dispatched shortly before 1 a.m. to the substation at 2405 Sargent Road in the Cedar Crest area of Dallas after reports of a large blaze. Upon arrival, crews encountered heavy fire conditions and thick black smoke rising from the facility.
Officials with Dallas Fire-Rescue said the initial strategy was to protect nearby structures and allow the fire to burn itself out due to the electrical hazards involved. However, responders coordinated with representatives from Oncor to safely de-energize the substation, allowing firefighters to begin suppression operations.
Because the fire involved energized electrical equipment, Dallas Fire-Rescue requested assistance from one of its Airport Rescue Firefighting units to apply foam to the blaze. A hazardous materials team was also dispatched to the scene.
Environmental agencies, including the Environmental Protection Agency, the Texas Commission on Environmental Quality, and local stormwater authorities, were notified and began monitoring the area for any potential environmental impact related to the smoke and firefighting efforts.
Fire officials said the blaze was largely knocked down by early morning hours, though crews remained on scene to cool hot spots and debris.
Oncor reported that no power outages occurred as a result of the fire, and service to customers was not disrupted. The cause of the fire remains under investigation.
