TUCSON, Ariz. (13 News) – A fiery rollover crash on Interstate 10 in Tucson on Wednesday<\/b><\/u><\/i> left one person dead and forced firefighters to confront a dangerous challenge — electric vehicle fires.<\/p>\n

The Arizona Department of Public Safety is investigating the crash, which happened in the eastbound lanes of I-10 near Valencia Road. DPS said a tractor-trailer carrying vehicles blew a tire, hit a guardrail, and rolled into the median.<\/p>\n

At least two of the vehicles on the truck caught fire and burned. The roadway was shut down for hours as crews worked into the night to clear debris and secure the scene.<\/p>\n

Tucson Fire Battalion Chief Lyle Steffens said the crew learned the two burning vehicles were EVs, which pose a particular challenge. You can\u2019t just dump water on them like you would for a normal vehicle fire.<\/p>\n

\u201cThere\u2019s a lot more hazards to our firefights, bystanders, the environment, you name it,\u201d Steffens said.<\/p>\n

Fire officials said the biggest concern in EV-related crashes is whether a lithium-ion battery pack is burning or at risk of \u201cthermal runaway,\u201d a chain reaction that can rapidly intensify and become difficult to extinguish. Those fires can also release dangerous chemicals.<\/p>\n

\u201cThey release really hazardous gases, fluorides, and all sorts of stuff that\u2019s extremely toxic,\u201d Steffens said.<\/p>\n

In this case, Tucson Fire said the battery packs did not fully ignite. Steffens noted one vehicle\u2019s battery pack was smoking after being exposed to flames, but it did not escalate into a full lithium-ion battery fire.<\/p>\n

\u201cOne of them had the battery pack smoking because it was exposed to fire,\u201d Steffens said. \u201cFortunately, it didn\u2019t have a thermal runaway event, and we didn\u2019t have to fight a true lithium-ion fire.\u201d<\/p>\n

Even so, crews used specialized equipment designed for EV incidents, including a fire blanket and a tool firefighters call the \u201cturtle,\u201d which sprays water underneath an electric vehicle to reach the battery area.<\/p>\n

\u201cWe just overwhelm it with copious amounts of water,\u201d Steffens said.<\/p>\n

The TFD said that as more EVs hit the road, crews are using those tools more often, but the threat remains a developing challenge for the fire service.<\/p>\n

\u201cWe have tools for fighting these. I wouldn\u2019t say that the fire industry or the electric car industry has really solved the issue yet,\u201d Steffens said. \u201cRight now, the fire service is trying to figure out what we do about it.\u201d<\/p>\n

DPS said more information about the crash will be released as the investigation continues.<\/p>\n
