A London Fire Brigade spokesperson said earlier: “Firefighters are at the scene tackling the industrial unit blaze. There is a lot of thick black smoke in the local area so we’d ask local residents to close their doors and windows.
"A number of gas cylinders are involved in the fire. Fire crews will be cooling them down as some cylinders can explode when exposed to heat."
The Brigade was called at 10.10am. Fire crews from Enfield and surrounding stations are at the scene and residents from nearby buildings are being evacuated.
The cause of the fire is not known at this stage.
