Chino Valley, AZ – On Thursday night just before 11 p.m., first responders were dispatched to a serious rollover involving a semi‑truck carrying the hazardous material hydrated lime on State Route 89 near Del Rio Ranch Road. The truck’s cab hung over the edge of a bridge, and the driver remained trapped inside the vehicle.
Emergency crews secure the scene
The Central Arizona Fire and Medical Authority (CAFMA) arrived to find white, powdered hydrated lime scattered across the roadway and surrounding area. Crews quickly established a safety perimeter to protect motorists and nearby residents from exposure.
Using specialized equipment, firefighters pulled the driver from the cab, performed on‑site decontamination, and transported him to a nearby hospital for evaluation. The driver’s condition was reported as stable, and he was released after receiving appropriate medical care.
Firefighter receives precautionary treatment
During the response, one CAFMA firefighter experienced irritation to the eyes and respiratory passages after contact with the lime dust. The firefighter was taken to the hospital for a precautionary evaluation. After a brief observation period, the firefighter was released later that night and returned to duty.
Multi‑agency coordination
The incident required a coordinated effort among several agencies, including the Arizona Department of Public Safety, Arizona Department of Transportation, Chino Valley Police Department, Copperstate Ambulance, Prescott Fire Department, and the Yavapai County Sheriff’s Office. Together, they ensured the scene was safely cleared, the hazardous material was contained, and traffic was restored as quickly as possible.
Hydrated lime, while commonly used in construction and agriculture, can cause severe irritation to skin, eyes, and lungs when inhaled or contacted in its powdered form. Proper handling and rapid decontamination are essential to prevent lasting health effects.
Public safety reminder
Local officials remind residents and drivers to obey detour signs and stay clear of emergency zones during incidents involving hazardous substances. Prompt reporting of spills and adherence to safety protocols help protect both first responders and the community.
The crash underscores the importance of well‑trained emergency personnel and inter‑agency cooperation in safeguarding the public during unexpected hazardous‑material events.
