Sylmar Propane Tank Fire: Emergency Response and Investigation Details

At 1:41 p.m. Wednesday, December 17, 2025, a propane tank ignited in the intersection of Sierra Highway and San Fernando Road in Sylmar, according to the California Highway Patrol. Emergency personnel arrived quickly, and a hazmat team was deployed to the scene.

Immediate Emergency Response

The first responders were dispatched to the location shortly after the initial report. By the time the crews reached the site, the propane tank was already burning. The crew assessed the situation and determined that the best course of action was to let the tank burn out while maintaining a safe perimeter. This decision was made to reduce the risk of an explosion and to protect surrounding structures.

Hazmat Team Deployment

A hazmat team was brought in to manage the hazardous materials involved in the incident. The team worked alongside regular fire suppression units, monitoring the scene for potential secondary hazards. Their presence ensured that any chemical or gas-related risks were contained and that the fire did not spread to nearby buildings.

Fire Suppression Strategy

Because the propane tank was actively burning, the response strategy focused on containment rather than aggressive suppression. The crew monitored the fire’s progression, allowing it to burn out naturally while keeping the area clear of civilians. No external water or foam was applied, as the fire was deemed too dangerous to approach directly.
