Crews resonding to hazmat call at landfill
Updated March 5
Great Falls Fire Rescue responded to a hazardous materials call at the High Plains Landfill, 142 Powerline Road on March 4.
GFFR responded along with Malmstrom Air Force Base, the Montana Air National Guard and Black Eagle fire departments responded when a City of Great Falls sanitation truck was found to have alerted sensors on a weight scale to possible hazardous materials.
Crews determined that a radiological source had been detected by weight scale monitors.
Incident Command contacted the state duty office and requested assistance from the Montana National Guard’s 83rd Civil Support Team, which supports civilian authorities on chemical, biological, radiological and nuclear, as well as hazmat, incidents.
The CST and responding fire departments were able to submit data to a federal lab and the results indicated that the radiological source was Iodine 131, which is commonly used in treating thyroid cancer or for imaging the thyroid, according a GFFR release.
The Iodine 131 at the landfill has been isolated and contained and there is no hazard to the public, according to GFFR.
The landfill was closed to the public Thursday afternoon as crews responded, but has since been reopened and is operating normally on March 5.
