Özet

Background / Objectives

Fire and explosion accidents represent a disproportionately hazardous category of maritime casualties, with official reports indicating they accounted for 9.5% of all injury-related events between 2015 and 2024 despite their comparatively low overall frequency. Although research consistently links such accidents to human and organizational factors, large-scale, systematically coded investigations of this specific accident type remain limited. This study aimed to identify the most and least prevalent human factor categories in maritime fire and explosion accidents by applying the Human Factors Analysis and Classification System for Maritime Accidents (HFACS-MA) framework to a decade-long sample of official casualty investigation reports.

Methods

A total of 226 fire and explosion casualties reported in the International Maritime Organization (IMO) Global Integrated Shipping Information System (GISIS) database for the period 2015–2025 were screened. Applying purposive sampling criteria — full-text availability in English, completed investigation status, and confirmed human factor involvement — 43 reports were retained (31 fires, 12 explosions). The analysis followed a two-stage procedure. First, three pilot cases were manually coded by the researchers to construct a standardized HFACS-MA reference matrix covering all five levels and 21 sub-categories. Second, the remaining 40 reports were coded using a large language model (LLM; Google Gemini 3.1 Pro) guided strictly by that matrix. Inter-coder reliability was assessed by independently re-coding three randomly selected AI-analyzed reports; agreement was approximately 86%, exceeding the 70% threshold recommended by Miles and Huberman (1994) for qualitative research. Frequency and percentage distributions were calculated for all HFACS-MA sub-categories.

Results

All 43 accidents contained at least one human factor code, yielding 278 individual HFACS-MA activations (mean 6.5 codes per accident). At the organizational level, Organizational Process was the most prevalent sub-category (f = 35; 81.4% of accidents), reflecting pervasive deficiencies in operational procedures and safety management system implementation. Physical Environment ranked second (f = 33; 76.7%), followed by Technological Environment (f = 28; 65.1%), Rule-Based Mistakes (f = 24; 55.8%), Inadequate Supervision (f = 21; 48.8%), Condition of Operator (f = 19; 44.2%), and Exceptional Violations (f = 18; 41.9%). In contrast, Software (f = 1) and Hardware (f = 2) were almost entirely absent, indicating that the dominant failure mode is human–machine interface design rather than outright technical breakdown. Night-time accidents predominated (67.7% of fires; 58.3% of explosions), container vessels were the most affected ship type for fires (n = 10), and tankers for explosions (n = 4).

Conclusions

Maritime fire and explosion accidents are inherently multi-causal, with human factors present across all five HFACS-MA levels. Organizational process deficiencies and adverse physical and technological environments are the most critical systemic vulnerabilities, while individual-level failures manifest primarily as rule-based mistakes and exceptional violations rather than skill-based errors. These findings suggest strengthening the operational implementation of the International Safety Management (ISM) Code, improving ergonomic standards for onboard alarm systems, and updating emergency response training curricula are the most impactful intervention priorities. The AI-assisted coding approach demonstrated high reliability and offers a scalable methodology for future large-scale maritime accident analyses.
