Fauji Fertilizer Company LimitedMirpur Mathelo Incident Investigation : An Advance Approach By: Shakir Imran
Synopsis • Background • Incidents Definitions • Incident Causation Model • Incident Investigation : Traditional Model • Rational Vs Advance Model Comparison • Incident Investigation: The advance model • FFC Mirpur Mathelo Methodology • FFC Mirpur Mathelo Experience • FFC OH&SMS Performance
Background During a study on incident investigation methodology and record following were observation: • In any year, 70~ 80% of accident were due to 20~ 30% of the root causes • These root causes are repetitive in the all the years (from 2003 on ward) • Actions were correction than the corrective actions.
Incident Work related event(s) in which an injury or ill health (regardless of severity) or fatality occurred, or could have occurred. (OHSAS 18001:2007)
Incident Causation Model Safeguard 03 Safeguard 01 Safeguard 04 Safeguard 02
The Alternative Arrangement Traditional Approach: • Identification of critical events • Actions to prevent their recurrence New Construction: • Interaction of critical events and human behaviors. • How these work together forms a system
Nature of Accident (Traditional Rational View) • Time line and sequence of the events before accident happening • Identification of critical events during this chain of events/ Failure of safeguards • Dealing with these identified critical event(s) (Active failures) to prevent reoccurrence (single loop learning)
Incident Investigation: The Advance Model • Time line and sequence of the events before accident happening • Identification of critical events during this chain of events/ failure of safeguards • Human contribution to loss • Identification of latent failures in root cause analysis (double loop learning)
FFC Mirpur Mathelo Methodology • Gap analysis between conventional and advance model methodology • A training plan is developed for the implementation of the following critical areas: • Human behaviors/ factors • Correction and Corrective Actions • Investigators biases • Risk assessment study is also revised and human factors/ behaviors were incorporated in the risk assessment study.
Human Failures: Human Contribution to Loss • Errors • Violations
Human Failures: Human Contribution to Loss Errors and Violations • Errors • Action Errors • Slips and Lapses (Skill Based Errors) • Thinking Errors • Poor Analysis/ Problem Solving (Rule based Errors) • Incomplete Information (Knowledge based Errors)
Human Failures: Human Contribution to Loss Cognitive Deficiencies • Perception • Memory • Decision • Action
Human Failures: Human Contribution to Loss • Violations • Routine: A rule exists but no one follows it • Situational: In effect the specific nature of the situation induces the violation • Exceptional: these are rare and occur when something has already gone wrong and people feel the need to improvise so as to correct the problem.
Correction and Corrective Actions • Active and Latent Failures • Single and Double loop learning
Active and Latent Failures • Active Failures Occurs in the close proximity of the incidents • Latent Failures Hidden and mostly available within the deficiencies of management systems
Single and Double Loop Learning Single Loop Learning • To change the behavior • e.g. Identification for retraining as a remedial action Double Loop Learning • To correct errors to change the identified program • e.g. Why training is not effective in first place ?
Investigator Biases • Satisficing • Heuristics: • Confirmatory evidence • Mental models • Groupthink • Hindsight
FFC Mirpur Mathelo Experience • We are in a process to implement this approach and certainly a new subject for us and in Pakistan. However positive impact on the statistics is already being observed. • Study has showed that this approach (originally developed by BSI) has Improvement area were identified in: • Management Systems • Training Plan Formulizations / Safety Trainings/ Orientation Structures • Risk assessment study • Job Safety Analysis • Job suitability analysis (Induction phase)
