More than 150 firefighters are battling a large warehouse fire in the industrial zone of Bobigny, Seine-Saint-Denis, on Wednesday [1].

The scale of the blaze has triggered a massive emergency response in a densely developed industrial area, creating significant smoke plumes visible from nearby regions.

The fire broke out early Wednesday afternoon [2]. Emergency crews identified the location as a warehouse likely situated on Rue Henri Gauthier, near the Pantin cemetery [3]. Local authorities said that no injuries have occurred at this stage [1].

Firefighters said the situation was "a very long operation, which will require several hours of fighting the fire" [4]. The size of the affected structure has been reported inconsistently, with estimates ranging from 4,000 square meters [5] to approximately 7,000 square meters [6].

The Prefecture of Seine-Saint-Denis issued warnings to local residents regarding the smoke, and the ongoing emergency operations [7]. Authorities have not yet determined the cause of the blaze, as the primary focus remains on containment and extinguishing the flames.

Crews continue to work on the scene to prevent the fire from spreading to adjacent industrial buildings. The operation remains active as of Wednesday afternoon.

"a very long operation, which will require several hours of fighting the fire"

The mobilization of over 150 firefighters for a single industrial site underscores the high risk associated with warehouse fires in the Seine-Saint-Denis region. Due to the concentration of industrial materials and the size of the structures, potentially up to 7,000 square meters, these incidents often require prolonged interventions to prevent catastrophic urban spread.
