A hazardous chemical spill in the road led to the closure of the intersection of Catalina Highway and Houghton Road on Saturday.

Rural/Metro Fire crews were sent to the scene at about 11 a.m. and determined it was a spill of muriatic acid, which is used in industrial applications and as a pool chemical. They blocked off the intersection and shut down the road along with Pima County Sheriff's Department personnel.

A hazardous materials team donned protective gear and applied soda ash to the acid to raise the pH, then removed the bulk of the soda ash in buckets from the road for disposal. The Pima County Offices of Emergency Management and Department of Transportation were notified to further mitigate the spill and assess the condition of the road, Rural/Metro said in a news release.
