Some first responders began coughing, vomiting and experiencing dizziness, authorities said.
The mayor said Thursday that officials were awaiting tests results.

Antonette Alguire, a volunteer firefighter in Mountainair, said she saw some emergency medical technicians and firefighters coughing, and vomiting.
Hospital officials said most of the people evaluated had no symptoms and were discharged.
Drugs were found in New Mexico home
Mountainair Mayor Peter Nieto said he spotted drugs at the home that sits along a dirt road and pointed to that as a possible factor in the deaths. He did not say what type of drugs he thought they were.
He dismissed carbon monoxide or natural gas exposure as possible causes for the health issues that the first responders experienced.
New Mexico State Police spokesperson Wilson Silver said there was no threat to the public and that investigators do not believe the substance was airborne.
New Mexico has a high number of overdoses
New Mexico had the fourth-highest rate of drug overdose deaths of any U.S. state in 2024, with 775 deaths, according to the most recent data available by the Centers for Disease Control and Prevention.
Residents around Mountainair, a town with less than 1,000 people, have voiced frustration about drug use in the community and elsewhere.
The mayor posted on social media that the town’s law enforcement officers and first responders work daily to protect the community and respond to difficult situations.
