Risk Analysis: Industrial Gas Leak Accident in Pohang on 05 November

Industrial Gas Leak

What is Risk Analysis in the Context of Critical-Infrastructure Events

Critical-infrastructure risk analysis assesses how industrial failures such as chemical leaks, fires, or explosions affect human safety, production continuity, and environmental stability. Pohang, home to South Korea’s largest steelmaking facilities, has faced repeated industrial incidents involving POSCO and Dongkuk Steel, highlighting vulnerabilities in process safety and emergency readiness. The 05 November 2025 gas leak fits into this recurring pattern, posing significant threats to worker safety, operational output, and regional environmental quality. Prompt containment and coordinated response are essential to prevent escalation and protect industrial and community assets.

Executive Summary

  • Date of Event: 05 November 2025
  • Location: POSCO Pohang Steelworks, Gyeongsangbuk-do, South Korea
  • Risk Category: Critical Infrastructure
  • Severity Score: 4 / 5
  • Confidence Level: 85 %

An industrial gas leak was reported at the POSCO Pohang Steelworks on 05 November 2025. Emergency services responded to reports of toxic gas emission within the facility. While details on the gas type, volume, or casualties remain unconfirmed, the risk profile aligns with previous industrial accidents in the region involving hazardous leaks, explosions, and worker fatalities. Operations are likely suspended pending safety clearance and investigation. Air quality, public health, and business continuity remain the primary areas of concern for the next 3–7 days.

Known Hotspots and Sensitive Areas

  • High Impact: POSCO Pohang Steelworks complex and adjacent industrial facilities.
  • Medium Impact: Residential zones near Donghaean-ro and Yeonil-eup.
  • Low Impact: Peripheral districts of Pohang and Gyeongju.

Wind direction and gas dispersion patterns may determine the scale of evacuation or shelter-in-place advisories.

Impact on Operations and Services

  • Industrial Activity: Partial shutdown at POSCO operations; potential suspension of nearby plants as precaution.
  • Mobility: Local road closures near Donghaean-ro to facilitate emergency access.
  • Utilities: Temporary power or gas isolation measures to prevent ignition.
  • Supply Chain: Disruptions to steel and raw-material logistics for 3–5 days.
  • Environmental: Airborne contamination risk requiring post-event monitoring and remediation.

Recommended Actions

  • Safety Protocols: Activate site emergency response plans and confirm personnel accountability. Issue PPE (respirators) and maintain shelter-in-place orders until clearance.
  • Operational Control: Isolate affected gas lines and storage units; conduct facility-wide air quality tests before resuming production.
  • Business Continuity: Alert downstream partners of possible delays; reroute deliveries and shipments via unaffected regional facilities.
  • Regulatory Coordination: Liaise with the Ministry of Environment and Gyeongsangbuk-do Disaster Office for compliance, investigation, and disclosure.
  • Crisis Communication: Assign a single spokesperson to release verified updates to staff, media, and government agencies to minimize misinformation.

Multidimensional Impact

The Pohang gas leak underscores South Korea’s ongoing industrial-safety challenges amid high-density manufacturing zones. Beyond immediate casualties or production loss, the incident risks eroding community trust, prompting regulatory scrutiny, and disrupting export supply chains. Environmental effects could extend to airborne pollutants and water contamination, affecting coastal ecosystems. Collectively, the event represents not just a localized emergency but a test of industrial resilience and public confidence in crisis management systems.
