#5 whys
The '5 Whys' root cause knife. Unpacking Japan's simple trick adopted by shift personnel to dissect genesis faults. Analyzing real cases where mere 'inattention' unraveled deeply-rooted gear failures.
Regular Incident Analysis: From Blaming Individuals to Systemic Solutions
Traditional blame-seeking in occupational health and safety incidents is ineffective and is giving way to a systemic approach, where every incident is viewed as a symptom of deep organizational problems. Regular analysis of even minor incidents allows identifying up to 80% of potentially dangerous situations before they escalate into severe accidents. Such an approach transforms industrial safety from a formal procedure into a living system that reliably protects the lives and health of workers.
Incident Investigation: Not About Blame, But Hunting for Root Causes
The article explains why a punitive "find and punish" approach when investigating an industrial incident is dangerous, and how failures due to the "human factor" hide systemic flaws. The author shows how switching to a "search for causes" helps discover weak links in occupational health and safety and work organization. Using the "5 Whys" method as an example, it examines a way to find the root cause of an accident and eliminate a real threat in production.
Exercise for Practicing the Identification of Accident Causes: Immediate, Underlying, and Root
The publication presents a practical exercise for determining the immediate, underlying, and root causes of an accident using a case study as an example. Based on a story about a female employee being injured on stairs, it is proposed to analyze the combination of factors that led to the incident. At the end of the material, the author provides their own version of the analysis for checking and comparing the results obtained.
Hazard Observation Cards Methodology as a Near Miss Management Tool
Implementation of a system for collecting and analyzing hazard observation cards (HOC) for near miss management. The practice includes a four-step HOC algorithm, accounting automation based on an internal IT solution, application of the "Five Whys" and "Bowtie" methods for investigation, and financial motivation of personnel for active risk identification.
Why Use a Structured Approach in Accident Investigation?
The effectiveness of workplace accident investigations directly depends on a methodology that allows moving from superficial analysis to true root causes. The article examines a structured approach that eliminates subjectivity and replaces finding fault with the systematic improvement of the occupational health and safety system. You will learn how applying established methods helps identify systemic flaws, implement effective preventive measures, and strengthen safety culture.
The "5 Whys" Method: A Simple Tool for Finding the Root Causes of Incidents
The "5 Whys" technique, developed by Sakichi Toyoda, allows during workplace incidents to move away from superficial factors and determine the true cause of a failure in a system or process. By sequentially asking the question "Why?", it is possible to reach the root of the problem, not to look for culprits, but to prevent a recurrence of the situation. The article demonstrates the algorithm for applying this tool using a practical example and explains its role in forming a systematic approach t...
The Deep Roots of Workplace Tragedies: Digging to the Very Core!
The article presents the results of an analysis of the root causes of occupational injuries at a fuel and energy complex enterprise for 2006–2023 using the "5 Whys?" and logical-graphical modeling methods. The study showed that the lack of communicative compatibility among workers is one of the main root causes of incidents and significantly affects the risk of injury. The author emphasizes the importance of assessing the communicative compatibility of personnel as a key direction for improving...
Internal Incident Investigations in Industrial Safety: Not a Punishment, but a Development Tool
Internal investigation of industrial safety incidents is aimed at finding systemic causes of events, rather than identifying those at fault. Implementation of this procedure allows for preserving the life and health of workers, minimizing economic damage, and avoiding penalties from regulatory bodies. The article examines the requirements for organizing investigations, the classification of incidents, and practical methods of cause analysis for training personnel.
"Learning from Mistakes" or How to Conduct a High-Quality Incident Investigation
Implementation of the A3 incident investigation methodology to shift from blame-seeking to systemic root cause analysis. The practice includes a step-by-step fact-gathering algorithm, application of analysis tools (timeline, cause tree, Ishikawa diagram, barrier diagram), and evaluation of corrective actions using an effectiveness-cost matrix.
HSE Integration into Production System Practices. NLMK Experience
Integration of HSE and operational efficiency processes through cross-functional teams and the Idea Bank system. Implementation of lean production tools (5S, A3, mapping, Five Whys) into daily HSE practices, including shift meetings and standard operating procedures.
HSE Incident Investigation: Goals, Objectives, Methods
Implementing a systemic approach to investigating all incidents, including micro-injuries, focusing on finding root causes instead of assigning blame. The practice involves the sequential application of analytical tools (5W1H, 4M analysis, "5 Whys") by cross-functional working groups and mandatory horizontal scaling of corrective measures to adjacent departments.
