Truck Overturns in Arizona, Spills Nitric Acid, Triggers Shelter-in-Place Alert
An emergency shelter-in-place has been issued for nearby residents after a truck carrying hazardous materials overturned on Feb. 14 on a highway in Tucson, Arizona.
Following a crash, a commercial truck tanker overturned on the Interstate 10 highway eastbound between Rita and Kolb roads, according to the Arizona Department of Public Safety.
“The tanker involved in this collision was hauling nitric acid in liquid form,” the Arizona DPS announced on Twitter of the HAZMAT spill.
Liquid nitric acid is a highly corrosive substance. In vapor or mist form, it can cause burning sensations to the eyes, nose, skin, and lungs. Exposure to high concentrations of this can cause pneumonitis and pulmonary edema, which can be fatal.
When nitric acid is exposed to air or contacts organic matter, it decomposes to create various toxic oxides of nitrogen, which include nitric oxide and nitrogen dioxide.
Shelter in Place Alert Issued
The Arizona Department of Transport (DOT) announced the crash around 3 p.m. local time. By 5:09 p.m., the Arizona DPS said the tanker was leaking hazardous material.
“Interstate 10 remains closed in both directions between Rita and Kolb roads in Tucson,” per the Arizona DPS. “Motorists should continue to avoid the area and seek an alternate route.” The DPS added in a Twitter post: “We anticipate an extensive closure. Please avoid the area.”
Meanwhile, the Arizona DOT said that there is “no estimated time to reopen the road.”
An emergency alert said that everyone within a one-mile radius of the crash should shelter in place. People are also advised to turn off heaters and air-conditioners that “bring in outside air.”
First responders were working to evacuate the area around where the truck overturned. The Arizona DPS Hazardous Materials Response Unit and multiple agencies were also working to respond to the incident. The other agencies include Tucson Fire Department, Tucson Police Department, Pima County Sheriff’s Department, and Marana Police Department.
