In brief
An explosion at the HABAS iron and steel plant in Aliaga on Nov. 9 during electric arc furnace maintenance caused 16 fatalities, with Turkish President Recep Tayyip Erdogan announcing the toll increase as investigations into possible negligence continue.
A massive blast at the HABAS iron and steel plant in Aliaga, Turkey, on Nov. 9 during planned maintenance of an electric arc furnace killed 16 workers, officials said Monday. The explosion, which caused severe structural damage and set flames that were later extinguished by emergency crews, has prompted a nationwide investigation into safety practices at the factory and the wider Turkish steel industry.
The blast occurred at approximately 12:00 p.m. local time (0900 GMT) when maintenance crews were inspecting and servicing a large electric arc furnace (EAF), a type of furnace that melts scrap steel by creating a high‑temperature electric arc between graphite electrodes and the molten metal. The sudden release of pressure and heat during routine maintenance operations led to the catastrophic explosion seen by witnesses.
Investigation and negligence
Erdogan announced at a press conference that the death toll had risen to 16 and that an investigation was underway to determine the exact cause of the blast and who might be responsible for any negligence. He said the investigation would focus on the plant’s safety protocols and maintenance practices, as well as the regulatory oversight that governs industrial safety in Turkey.
Erdogan said at a press conference that an investigation was underway to determine the cause of the blast and those responsible for any negligence.
The statement echoed reports from the Izmir Governor’s Office, which confirmed the timing of the explosion and the fact that it happened during a scheduled maintenance window. According to a statement from HABAS, the blast occurred while technicians were conducting routine inspections of the furnace’s cooling system, a highly regulated activity that requires strict adherence to lock‑out tag‑out procedures.
Several high‑ranking officials, including the Labor and Social Security Minister and the Energy and Natural Resources Minister, have traveled to Izmir to oversee the situation and meet with plant representatives. The presence of these officials underscores the importance of the incident for national industrial safety policy and highlights Turkish authorities’ willingness to direct resources toward a thorough investigation.
Official statements also noted that the fire sparked by the blast was quickly brought under control by local fire services and that rescue teams were working to evacuate and aid injured workers. While the death toll rose to 16, dozens of other workers remained reported as injured or trapped, according to local authorities.
Several news outlets, including Xinhua, Big News Network, and the Union‑Bulletin, corroborated the facts reported by the Turkish government. The Union‑Bulletin’s coverage included a statement from the Turkish president, while the Big News Network confirmed the timing and the scale of the explosion. An additional source, Intellinews, reported that at least six workers were killed in a similar incident earlier in the month, indicating a pattern of safety concerns that may warrant a broader industry review.
Electric arc furnace safety
EAFs, which are increasingly used in modern steel production due to their relatively lower emissions and flexibility in processing scrap metal, are inherently hazardous. When the electrodes are lowered into the molten pool, the electric current can be high enough to generate temperatures exceeding 3,000 °C. Maintenance operations on an EAF require strict de‑energization protocols and careful handling of high‑pressure systems. The hazards of thermal shock, gas build‑up, and electrode fracturing can, if not properly managed, culminate in explosive events.
According to safety guidelines published by the International Council on Mining and Metals, an EAF maintenance procedure typically includes: (1) full power isolation; (2) verification of all pressure relief valves; (3) inspection of electrode welds; and (4) controlled cooling of the furnace structure to avoid thermal expansion mismatches. Failure to follow any of these steps can lead to catastrophic failure of structural components, which was the likely scenario in the Aliaga incident.
Industry experts argue that lessons from similar incidents—such as the 2018 blast at a steel plant in western Turkey’s Balcama region—should have prompted stricter enforcement of international safety codes. In that case, the Turkish Ministry of Industry and Mines issued a directive on safety compliance that required all EAF operators to conduct quarterly safety drills. Whether HABAS adhered to that directive remains under investigation.
Producers across Turkey estimate that the national steel sector accounts for roughly 5 % of the country's GDP and employs around 250,000 people. A major incident such as the Aliaga blast, therefore, has wide economic implications beyond the tragedy of the 16 deaths. In addition to immediate financial losses from halted production and potential cleanup costs, the incident could influence future policy toward stricter regulations or even push Turkish steel producers to adopt more modern, automated furnaces that reduce human exposure to high‑risk operations.
International bodies such as the World Steel Association have responded by reminding member countries that occupational safety remains a priority in the era of advanced automation. Their advisories emphasize that the transition to electric arc furnaces should be accompanied by comprehensive training programs for maintenance staff over a two‑year period, which would encompass both theoretical and practical components. They also advocate for real‑time monitoring of furnace parameters using sensors that can detect abnormal pressure, temperature, or vibration readings, thereby providing early warnings before a potential loss of control.
Depending on the findings of the ongoing investigation, there may be legal and regulatory actions pending against HABAS. In Turkey's legal framework, companies found to have violated Labour Law can face fines up to 10 % of their annual revenue and potential criminal charges for employees or executives who breached safety responsibilities. Potential civil lawsuits for the families of the victims could also emerge, dropping pressure to resolve the case swiftly.
In the meantime, the Turkish government has pledged to provide medical assistance and counselling to the families of the deceased and injured workers. In a televised statement, the Energy and Natural Resources Minister emphasized that the government would ensure that affected families receive full compensation and access to mental health support, citing the Ministry’s commitment to occupational safety.
The explosion also sits at the intersection of several global trends: the shift toward electric arc furnace usage, the push for lower carbon steel production, and increasing scrutiny of industrial safety worldwide. As nations decree tighter environmental and safety regulations, incidents such as the Aliaga blast expose gaps in the implementation of best practices. Industry observers are watching closely to see if Turkish authorities will revise their guidelines for furnace maintenance or if international bodies will issue new compliance standards for EAF operators.
As the investigation proceeds, Turkish officials are expected to release detailed reports on safety lapses, if any, and steps to fortify industrial safety protocols. The event has prompted calls from both domestic trade unions and international safety associations for a review of all operating electric arc furnaces in Turkey to ensure compliance with the most recent safety standards. The outcome should shape the future of Turkey’s steel industry as well as its policy stance on industrial safety and environmental stewardship.
