Industrial fire was initially contained before deadly vapor explosion

by Featured NewsIncidents

Industrial fire kills two firefighters in Wando

Two firefighters died after a vapor explosion during an industrial fire at a seafood processing facility in Wando County, South Jeolla Province, South Korea, on 12 April.

The Dong-A reported that Senior Fire Sergeant Park Seung-won, 44, of Wando Fire Station and Firefighter Noh Tae-young, 30, of Haenam Fire Station were trapped inside the structure when conditions escalated.

The fire started in a first-floor freezer used for seaweed storage.

A worker was removing epoxy flooring with a torch at the time of ignition.

Fire crews arrived at 08:38 and achieved initial suppression within nine minutes.

The fire then reignited and prompted a second operational phase.

About three minutes into that response, a vapor explosion occurred within the enclosed space.

The explosion caused a rapid spread of flames consistent with flashover conditions.

Both firefighters were unable to exit the structure.

Investigation examines industrial fire conditions and staffing

The Dong-A reported that preliminary findings suggest flammable vapours accumulated inside the sealed warehouse environment and were then ignited by an ignition source.

Authorities referenced a comparable 2020 logistics centre explosion in Icheon that resulted in 38 fatalities.

An investigation is ongoing into compliance with operational and site safety requirements.

The review includes the use of open flame equipment in confined industrial environments.

It is also examining adherence to the two-person work rule during hazardous operations.

The incident has prompted review of staffing levels across local fire stations and deployment practices during high-risk incidents.

It has been reported that Noh was primarily assigned to emergency medical services and had been redeployed to firefighting duties due to staffing shortages.

Park had 19 years of service and is survived by his wife and three children.

Noh was in his fourth year of service and had been preparing for his wedding later this year.

Authorities have indicated that findings from the investigation will inform any required changes to safety procedures and operational protocols.

Three firefighter fatalities have been recorded in the line of duty this year.

Daejeon factory blaze in Korea leaves 14 dead and dozens injured

by Featured NewsIncidents

Korea factory fire kills 14

A fire at a car parts factory in Daejeon, South Korea, killed 14 people and injured nearly 60 others after breaking out on Friday afternoon.

The Guardian reported that about 170 workers were believed to have been inside the three-storey building when the fire started.

Firefighters later confirmed that all of the people initially reported missing had been accounted for after a search of the wreckage.

The fire was not fully extinguished until Saturday afternoon local time.

Video footage from the scene appeared to show workers jumping from the first floor as the fire spread through the building.

Nam Deuk-woo, a local fire chief, told the New York Times that the fire had spread so quickly that by the time firefighters arrived, workers had already started jumping out of windows.

Response delayed by collapse risk and chemicals

The Guardian reported that firefighters faced delays in reaching the building because of concerns that the structure could collapse and because sodium stored on site had to be removed before water could be applied.

Sodium can explode when mixed with water, according to the report.

More than 200kg of highly reactive chemicals were recovered from the site.

Large plumes of black smoke were seen rising from the steel-framed building as crews used cranes to direct water onto the fire.

More than 500 firefighters, police and emergency personnel were deployed to the scene.

Two unmanned firefighting robots were also used to cool the building and reach areas that were too dangerous or difficult for rescuers to access.

Emergency workers said some of the injured suffered smoke inhalation and others were hurt after jumping from the building.

Nine of the 14 victims were found in a third-floor space reportedly used as a gym locker room.

Some of the deceased were so badly burned that DNA testing was required to confirm their identities, according to the New York Times.

Investigation continues after deadly Korea blaze

The Guardian reported that the cause of the fire remains under investigation and that a witness told Yonhap news agency they had heard an explosion before the blaze.

Fire officials told Reuters that the factory is owned by car parts supplier Anjun Industrial, which makes engine valves and supplies companies including Hyundai and Kia.

The incident is the deadliest factory fire in South Korea since 2024, when 23 workers died at a lithium battery plant in Hwaseong near Seoul.

Following that incident, the chief executive of battery manufacturer Aricell was sentenced to 15 years in prison.

South Korea’s president, Lee Jae Myung, has called for improved worker protections, with official statistics showing that more than 10,000 people died at work in the country between 2000 and 2024.

In a statement on the company’s website, chief executive Sohn Ju-hwan said that the company would fully cooperate with authorities, investigate the cause of the accident, review its safety systems and inspections and swiftly implement all necessary measures to prevent a recurrence.

Fire prevention lessons emerging from data centre battery failures

Data centre fire sparks calls for improved battery safety

A data centre fire in South Korea has renewed attention on global battery safety and the need for stronger fire prevention measures.

According to IDTechEx, the incident occurred on Friday 26 September in Daejeon, around 85 miles from Seoul.

The fire began after a suspected battery explosion triggered a thermal runaway event involving almost two hundred lithium-ion battery packs.

The blaze disrupted hundreds of online government services and has been described as one of the most severe of its kind in the country.

IDTechEx said the incident demonstrates that, although the rate of battery fires per gigawatt-hour deployed has fallen, the overall number remains high due to global growth in battery installations.

The company added that while regulations have improved since 2020, further work is needed to make large-scale lithium-ion systems safer.

Thermal runaway risks in lithium-ion batteries

IDTechEx explained that thermal runaway occurs when exothermic reactions inside a battery cause further heat-producing reactions, increasing the likelihood of combustion.

The process can move rapidly between battery cells and spread from one pack to another within minutes.

The firm noted that in large installations such as data centres, this can result in severe damage, financial loss and disruption to essential services.

In South Korea alone, the National Fire Agency reported 296 battery fire incidents during the first half of 2025, leading to 23 casualties and property damage of 22.4 billion KRW.

The agency recorded 543 battery fire incidents across the whole of 2024 and 359 in 2023, showing a continued upward trend.

IDTechEx linked this rise to increasing use of batteries in electric vehicles and stationary storage systems.

One of the country’s most serious incidents occurred in June 2024 at a factory owned by battery manufacturer Aricell, where 23 workers died following a fire caused by a battery fault.

Data centre demand increases global safety pressure

IDTechEx said growing demand for artificial intelligence and cloud services is driving the expansion of global data centres and their energy requirements.

The company estimated that data centres will use around 75 gigawatts of electricity in 2025, with demand expected to more than triple within ten years.

Battery energy storage systems (BESS) are being increasingly used in these facilities to provide renewable power, stabilise grid peaks and replace diesel generators.

IDTechEx said this trend is increasing the urgency for stronger safety rules, particularly in areas such as thermal management and runaway prevention.

The firm compared current regulatory frameworks, noting that the United States applies Underwriters Laboratories (UL) standards within National Fire Protection Association (NFPA) codes, while Europe relies on self-declared CE marking.

It said China is taking steps to improve electric vehicle battery safety with regulation GB 38031-2025, the first in the world to require “no fire, no explosion” standards, which will come into force in July 2026.

However, IDTechEx noted that similar global regulation does not yet exist for BESS safety, leaving many regions without unified standards.

Safety improvements and future technologies

IDTechEx identified several ways to improve battery safety in data centre environments.

The first is enhanced thermal management, which includes both active technologies such as liquid cooling and passive fire protection using ceramic, mica and foam materials.

The second is improved diagnostics and monitoring, combining gas, pressure and humidity sensors with artificial intelligence (AI) and machine learning to detect faults before overheating occurs.

The third is the use of alternative storage technologies such as redox flow batteries or solid-state batteries, which use non-flammable or solid electrolytes and may present lower fire risks.

According to IDTechEx, large-scale adoption of these technologies depends on supportive regulation and global standards that enable consistent testing and deployment.

The firm said that while lithium-ion batteries are not inherently safe, their risks can be reduced through better system design and management.

It concluded that progress will depend on transparent reporting of failure causes and industry-wide cooperation on safety standards.

Relevance for fire and safety professionals

This development is particularly relevant for data centre facility managers, electrical engineers, and those involved in energy storage design, regulation and inspection.

The Daejeon incident highlights the hazards associated with lithium-ion batteries in large installations and the operational risks of thermal runaway.

For fire safety officers and risk assessors, the case reinforces the need for robust suppression systems, battery room segregation, and reliable early warning sensors in sites using battery energy storage systems.

Professionals involved in system specification and procurement may also need to consider alternative battery chemistries, improved cooling methods and third-party certification standards as key safety criteria in future installations.

The issue is likely to remain a focus as global data centre and renewable energy capacity expand in parallel.

Wildfires in South Korea force evacuations and destroy 1,300-year-old temple

by Breaking NewsWildland Fire

South Korea faces one of its most destructive wildfire events in recent history

Wind-driven wildfires have burned across southern South Korea, killing at least 18 people, destroying more than 200 structures and prompting the evacuation of 27,000 residents.

According to reports from the Guardian and Korea Times, fires that started across the country over the weekend have spread rapidly due to dry conditions and strong winds. Over 8,700 hectares of forest have been destroyed, and more than 6,500 emergency responders have been mobilised.

The Korea Forest Service said multiple blazes, including in Uiseong, Andong, Sancheong and Ulsan, were among the largest ever recorded in the region. Prime Minister Han Duck-soo urged agencies to prepare for the worst-case scenario.

Fires destroy homes and cultural heritage sites in southeastern regions

Among the areas most affected is Uiseong in North Gyeongsang Province, where approximately 65 percent of the fire had been contained by Monday, according to the Korea Forest Service. The fire destroyed Gounsa Temple, a Buddhist temple dating to the seventh century.

The Korea Heritage Service confirmed the temple’s destruction, adding that national treasures, including a stone Buddha statue, had been evacuated in advance. No injuries were reported at the site.

Thousands were forced to evacuate from Uiseong, Andong, Sancheong and Ulsan. Temporary shelters, such as schools and gyms, were opened to accommodate evacuees. Officials also closed roads and issued evacuation orders in the coastal town of Yeongdeok.

Helicopter crash halts aerial firefighting operations

A helicopter responding to the fire in Uiseong crashed, killing the pilot. As a result, the Korea Forest Service suspended all firefighting helicopter operations nationwide.

Over 130 helicopters were originally deployed, but efforts were curtailed due to wind conditions and safety concerns. Officials also reported that around 9,000 personnel had been deployed, with operations continuing on the ground where possible.

The ministry of the interior and safety said the fires were only partially under control due to worsening weather conditions.

Government declares special disaster zones and mobilises additional support

The Korean government designated Uiseong, Ulju and Hadong as special disaster zones. This allowed for accelerated deployment of personnel, financial support for residents and wider use of state resources.

According to the Korea Times, these areas suffered the most extensive damage. The prime minister’s office confirmed that additional equipment and evacuation support had been sent to the affected areas.

Residents near Andong University and in several villages were ordered to evacuate as fires continued to spread despite initial containment efforts.

Fires linked to dry weather and rising temperatures

Meteorological data from the Korea Meteorological Administration indicated that the spring season has been unusually dry, with elevated temperatures and high winds creating conditions favourable to wildfire spread.

Experts have warned that these fires align with trends observed in recent years. According to the Korea Forest Service, the area affected by wildfires has increased five-fold between 2015 and 2024.

The Korea Rural Economic Institute reported in May 2024 that wildfires are no longer confined to mountainous eastern regions. They are now occurring nationwide due to high winter temperatures and long dry spells.

Climate change cited as key driver of wildfire scale and frequency

Researchers and international agencies attribute the growing severity of wildfires to climate change. A 2022 United Nations Environment Programme report stated that extreme wildfires have doubled globally over the past two decades.

Forest disaster expert Lee Byung-doo from the National Institute of Forest Science said the Uiseong fire was spreading with “unimaginable” speed due to wind conditions. He added: “We have to admit large-scale wildfires are going to increase and prepare more resources and manpower.”

UNEP executive director Inger Andersen said: “We have to minimise the risk of extreme wildfires by being better prepared: invest more in fire risk reduction, work with local communities, and strengthen global commitment to fight climate change.”

Pressure grows for long-term preparedness and improved response strategies

Local leaders and experts have called for more proactive measures. Lee Chul-woo, governor of North Gyeongsang Province, urged the central government to introduce more advanced wildfire response equipment and secure increased budgets for prevention.

Calls have also been made for stronger regional coordination and public awareness efforts. The UNEP has advocated for combining scientific monitoring with local knowledge in wildfire prevention.

Despite short-term containment efforts, officials continue to monitor conditions closely due to continued dry weather and ongoing risks of flare-ups.

Prisons and transport infrastructure also affected by spreading fires

Local media in South Korea reported that 2,600 inmates were being relocated from a prison in Cheongsong County, near Uiseong. The justice ministry did not immediately confirm the reports.

Officials in affected regions have shut down roads to prevent civilian access to danger zones. Emergency services continue to monitor wind patterns, which have previously caused fires to reignite in areas considered under control.

Efforts remain focused on protecting vulnerable populations and preventing the fires from reaching additional residential zones or infrastructure.

Wildfires in South Korea force evacuations and destroy 1,300-year-old temple: Summary

South Korea has experienced one of its largest wildfire events in recent history.

Wind-driven fires burned over 8,700 hectares of forest and destroyed more than 200 structures.

At least 18 people were killed.

Approximately 27,000 residents were evacuated across several southeastern regions including Uiseong, Andong, Sancheong and Ulsan.

A helicopter crash during firefighting operations killed one pilot, and aerial operations were suspended.

Gounsa Temple, a seventh-century Buddhist site, was destroyed.

The Korea Forest Service reported a five-fold increase in wildfire damage from 2015 to 2024.

The Korean government designated three areas as special disaster zones.

Climate change, higher temperatures and prolonged dry conditions were identified as contributing factors.

The UN Environment Programme and domestic experts called for better preparedness and investment in prevention.

The Korea Meteorological Administration confirmed abnormal spring weather patterns.

Reports suggested the relocation of inmates from a prison in Cheongsong due to nearby fires.

President Yoon orders scientific fire safety measures after Hwaseong fire in South Korea

by Featured NewsSafety

President Yoon calls for improved fire safety measures in South Korea

President Yoon Suk Yeol has directed his administration to develop “scientific safety measures” in response to a deadly fire at a lithium battery factory in Hwaseong, Gyeonggi Province, South Korea.

As reported by The Korea Herald, during a Cabinet meeting on Tuesday, Yoon instructed the Ministry of Interior and Safety, the Ministry of Employment and Labor, and the Ministry of Science and ICT to enhance their cooperation.

The goal is to create risk detection technologies and firefighting techniques tailored to specific chemical substances.

Yoon emphasised the need for updated safety measures, highlighting that the current advancements in firefighting technology and workplace safety have not kept pace with the growth of new industries.

Deadly factory fire in Hwaseong, South Korea

The fire occurred on June 24 at a lithium battery factory operated by Aricell in Hwaseong, resulting in the death of 23 workers, primarily foreign subcontracted laborers.

The victims, which included 12 women and five men from China, and one Laotian national, succumbed to asphyxiation as the fire spread rapidly through the facility, which housed approximately 35,000 battery cells.

This incident is noted as one of the deadliest workplace accidents in recent years, especially for foreign workers.

A preliminary police investigation revealed that the swift spread of the fire within the factory was a key factor in the high fatality rate.

In response, the government’s Central Disaster Management Headquarters announced plans to inspect around 500 lithium battery plants across the country for safety compliance.

Opposition criticism of government oversight

Representative Park Hong-bae of the main opposition Democratic Party of Korea criticised President Yoon’s administration for its approach to workplace safety.

During a press briefing at the National Assembly, Park argued that the reduction in inspections of corporations’ practices, such as illegal subcontracting, by approximately 70 percent during Yoon’s tenure, has contributed to increased workplace hazards.

Park attributed the administration’s pro-business, anti-worker policy stance as a factor in the Hwaseong fire.

Park also highlighted that Aricell’s Hwaseong plant had received financial incentives for achieving high safety standards in state risk assessments over the past three years, despite claims from bereaved families that the workers lacked adequate safety training.

Calls for technological advancements in safety

President Yoon has called for the development of new fire prevention techniques specifically designed for chemical substances in batteries.

He stressed the importance of creating technologies that can pre-emptively detect fire hazards, utilising advancements such as artificial intelligence, the Internet of Things, and sensors.

These innovations are aimed at protecting lives and ensuring workplace safety.
