Firefighters have been tackling a large blaze at a warehouse on a Greater Manchester trading estate.
Ten crews and two aerial appliances were at the scene in Little Hulton, where the fire was "well alight".
Crews were called at about 01:30 GMT to the fire at the warehouse on the Worsley Trading Estate.
Greater Manchester Fire and Rescue Service warned residents to keep doors and windows shut and not to touch "any white asbestos" they see in the area.
Manchester Road West at junction four of the M61 has reopened but traffic remains slow.
Wharton Primary School said it will be closed until Friday.
By 05:00 the service said firefighters "have now surrounded the fire and brought it under control".
"Low level asbestos" that has been blown onto surfaces in the area is "nothing to worry about" but should not be touched, the fire service said.
"If you see any white asbestos on the ground or surfaces please stay away and do not touch it," the service warned residents.
Salford City Council advised anyone with debris on their windscreen to "damp it down using water" and "flush away small particles" into the drain.
It said larger pieces of debris should be picked up with gloves and placed "in two plastic bags" to be disposed of at local tip but said "don't sweep, vacuum or break down as it could create airborne dust".
Staff from North West Ambulance Service and Greater Manchester Police officers have also been assisting at the scene.
