UL recommendations now in after 2019 lithium battery fire in Arizona

UL Firefighter Safety Research Institute (FSRI) today released a report detailing an April 2019 deflagration incident at a 2.16-MWh lithium-ion battery energy storage system (ESS) facility in Surprise, Arizona. The report provides a detailed technical account of the explosion and fire service response, along with recommendations on how to improve codes, standards, and emergency response training to better protect first responders, maintenance personnel and nearby communities.

“The ability to study lithium-ion battery-related fires on this scale with first-person accounts from the responding firefighters is critically important to protecting the lives of first responders in similar situations,” said Steve Kerber, vice president of research at UL FSRI. “We’re dealing with new technology, which brings about new fire-related hazards. We have an opportunity to learn from this incident and improve future outcomes by sharing resources and enhancing training and safety protocols.”

This report is a first-of-its-kind research effort from UL FSRI to capture the experience of surviving firefighters to better understand a potentially devastating situation. Four career firefighters with specialized hazardous materials (hazmat) training were severely injured in the explosion. They recounted their experience to help inform the report, the investigation team’s understanding of how the fire and gases behaved, and subsequent recommendations for ESS safety training.

“Typically, these kinds of events are examined when a fatality occurs,” Kerber continued. “But with this report, we’re trying to make sure the firefighter experiences are taken into account, providing valuable context to the findings so that they can be channeled into actionable insights for other fire service personnel to prevent future close calls and potential fatalities. We’re incredibly grateful for Peoria and Surprise Fire-Medical teams and Arizona Public Service for providing information to support learning from this incident.”

Lithium-ion battery ESS facilities have proliferated in recent years, presenting new challenges for the fire protection community. Sourcing the experiences of the firefighters, the UL FSRI report recommends new standards and codes for ESS sites, research programs, and curricula. Recommendations include fire service training with an emphasis on ESS safety, remotely accessible gas monitoring systems, explosion prevention protection, and full-scale testing research to understand the most effective and safest tactics for fire service response to lithium-ion battery ESS incidents.

    An aside, Fluence the company that put together these cargo container energy storage units, has introduced their series 6 battery storage technology. There are three flavors, Gridstack, Sunstack and Edgestack. It seems like Fluence is going away from cargo containers towards battery blocks that are about 10 x 10 x 10 feet and stand alone.

    APS paid $1.25 million in workman’s comp., more than likely for the 8 firemen, 4 hurt badly in this incident. The upside such as it is, this time, there were survivors that could give accounts of what happened from when the fire department entered the site to when they tried to stab an air sample from the cargo container, when it went up like an M80 in a tin can.
