A HAZMAT warning has been issued for people east of Mitchell Fwy in Neerabup.
About 10.40am a Department of Fire and Emergency Services spokesman said the HAZMAT fire was a pile of rubbish about 50m by 50m that was likely to burn for a couple of hours.
People in an area bounded by Anchorage Dr N and Hester Ave to the north, Wanneroo Rd to the east, Burns Beach Rd to the south and the coastline to the west may be affected by smoke.
Firefighting crews from Butler, Quinns Rocks, Joondalup, Duncraig, Cockburn and Bullsbrook are in attendance.
As a precautionary measure, people in the area should remain inside, out of the smoke or fumes, with doors and windows closed.
Air conditioners should also be switched off.
People should stay away from the area but if you are already in the area take advice from emergency services personnel.
People with medical concerns should contact their local doctor or call Health Direct on 1800 022 222.
Roads have not been closed.
