Key Cause Analysis
Q. Why did this incident occur?
Since the specific cause of the accident is not presented in this article, this is an estimated analysis based on common factors of explosion incidents in defense/chemical manufacturing processes.
- Human Factors (Estimated): Failure to comply with safety regulations during work, lack of familiarity with handling standards when handling hazardous materials, or possibility of operational errors.
- Equipment Factors (Estimated): Abnormal internal pressure rise in chemical transfer/mixing equipment, degradation of explosion-proof equipment performance, or possibility of static electricity eliminator malfunction.
- Environmental Factors (Estimated): Confined work environments where gas and dust easily accumulate, or dry weather conditions prone to static electricity generation.
- Management Factors (Estimated): Insufficient implementation of Process Safety Management (PSM), or failure to conduct pre-work risk assessments and gas concentration measurements.
Why It Is Dangerous On-Site
In actual workplaces, chemicals, high-pressure gases, and explosives handled in defense and aerospace-related manufacturing processes can lead to major explosions with even minor static electricity, sparks, or temperature changes. In particular, explosion accidents go beyond simple injuries to cause fatal casualties and equipment destruction, making prevention the top priority. Aging equipment, non-compliance with safety regulations during maintenance work, and malfunctioning gas leak detectors are potential risk factors that are difficult to detect on-site. Thorough management of explosion-proof equipment, pre-work gas concentration measurement, and static electricity prevention measures are essential.
Prevention Checklist
- Inspect the installation and maintenance status of explosion-proof electrical equipment within explosion hazard areas (hazardous zones)
- Constantly verify the normal operation of flammable gas and vapor leak detection and alarm systems
- Inspect equipment grounding status and the wearing of anti-static clothing to prevent static electricity generation
- Issue a Permit to Work (PTW) and conduct gas concentration measurements before hot work (welding, cutting, etc.)
- Secure emergency evacuation routes and regularly conduct explosion and fire evacuation drills for workers
- Periodically evaluate the implementation status of the Process Safety Management (PSM) report for handling chemicals and hazardous substances
Relevant Regulations
- Occupational Safety and Health Act, Article 38 (Safety Measures): An employer shall take necessary measures to prevent hazards caused by explosive, combustible, and flammable substances.
