A fire erupted at a lithium battery factory in Hwaseong, South Korea on June 24, 2024, resulting in the deaths of 22 workers. The blaze, which began with a series of explosions inside a warehouse containing 35,000 battery cells, quickly intensified, causing widespread destruction and loss of life.
The fire started around 10:31 a.m. and was largely extinguished in about six hours. The factory, operated by primary battery manufacturer Aricell, is in Hwaseong, a central industrial hub approximately 90 minutes southwest of Seoul. The victims included 18 Chinese workers, two South Koreans, and one Laotian. Two people sustained major burns and are receiving treatment.
“The fire likely spread too quickly for workers to escape due to the highly flammable nature of battery materials,” said a local fire official. Officials said victims may have died quickly from toxic gases set off during the explosion.
The exact cause of the explosions remains unclear. However, experts suggest that materials used in the batteries, such as nickel, likely contributed to the rapid spread of the fire. “Battery materials like nickel are easily flammable, so the fire probably spread too quickly for workers to escape,” said Kim Jae-ho, a Fire and Disaster Prevention professor at Daejeon University.
South Korean President Yoon Suk Yeol visited the scene to oversee the response and offer condolences to the victims’ families. Interior Minister Lee Sang-min emphasized the need to prevent hazardous chemicals from contaminating the surrounding area, reflecting the government’s concern over environmental and public safety.
Despite recent legislative efforts to improve conditions, this incident highlights ongoing safety issues in South Korea’s industrial sector. South Korea has a history of fatal industrial accidents, often attributed to negligence and insufficient safety measures. The country’s government introduced laws two years ago to hold company executives accountable in the event of fatal accidents, aiming to enhance corporate responsibility and worker safety.
Established in 2020, this factory produced lithium primary batteries for sensors and radio communication devices. Aricell is majority-owned by S-Connect, which saw its shares drop by 22.5% following the incident. The tragedy has raised concerns about the safety standards in the rapidly growing battery manufacturing industry, which is critical for the global supply chain of electric vehicles and renewable energy storage.
In response to the incident, the South Korean government has proposed tightening safety measures for energy storage systems (ESS). These measures include installing ground-fault detectors, fire extinguishing systems, and devices to mitigate internal pressure in battery cells during thermal runaways. These steps aim to prevent similar tragedies and improve the overall safety of battery manufacturing and storage facilities.
