LARIMER COUNTY, Colo. — An explosion injured two adults and one juvenile Tuesday evening, the Larimer County Sheriff’s Office said.
The victims were working on an excavation project in the 3300 block of South County Road 1 in Timnath when an “unintended explosion” occurred around 5:20 p.m., the sheriff’s office said.
The three were taken to Medical Center of the Rockies with critical burns.
The two adults were then transferred to University of Colorado Hospital. The sheriff’s office said Wednesday said a 35-year-old male and 22-year-old male were in critical but stable condition. A 12-year-old boy was transferred to Children’s Hospital Colorado in Aurora where he was in stable condition Wednesday.
The sheriff’s office said there was no damage to the house. The explosion happened away from the structure. Crews from Poudre Fire Authority monitored air quality.
The sheriff’s office said there was no evidence of open gas lines and there was no known threat to the public.
“Carbon monoxide buildup in the excavation site may have contributed to the explosion,” the sheriff’s office said.
The cause of the explosion was under investigation.
