An early-morning fire triggered a significant emergency response Saturday in Montebello.

At approximately 5:18 a.m., the Tallman Fire Department was dispatched to a reported dumpster fire at 50 Dunnigan Drive. Upon arrival, firefighters encountered heavy smoke coming from inside a warehouse, prompting an immediate upgrade to a structural fire response.

Mutual aid was requested from the Suffern Fire Department, Hillburn Fire Department, and Mahwah NJ Fire Department. Ramapo Police, Faist EMS and Rockland Paramedics also responded to the scene.

Fire crews located a trash compactor burning inside the building, with smoke spreading throughout the structure. The compactor was removed to the exterior of the warehouse, where firefighters were able to knock down the fire.

Due to heavy smoke conditions inside, Mahwah firefighters deployed their fan boat to assist with ventilation efforts. Crews remained on scene for overhaul and smoke removal operations before clearing the incident at approximately 7:00 a.m.

No injuries were reported.
