The New Mexico city of Albuquerque issued a health warning after a major fire broke out in a nearby plastics facility, spreading hazardous pollutants.
The blaze was "contained" Sunday evening and there is no more significant smoke, but firefighters are still on the scene monitoring hot spots, the county's environmental health agency said.
The Albuquerque-Bernalillo County Air Quality Program issued a health alert Sunday over the fire. "Plastics are burning and the smoke contains hazardous air pollutants," officials said.
The fire started outside of the plant but it quickly spread and required more responders, officials said at a news conference.
Albuquerque Fire Rescue Lt. Jason Fejer said Sunday that fully extinguishing the inferno could potentially take days. Two acres of wildland had been burned as of Sunday.
