Study Notes

Root Cause Analysis Overview

Distinction between immediate cause (obvious factors) and root cause (underlying systemic issues).
Various factors contribute to incidents, including people, equipment, material, environment, and processes.

Workplace Incidents

Defined as unplanned, unwanted events that disrupt work, often leading to injuries or property damage.
Investigating incidents helps to determine costs, compliance with regulations, and improve safety programs.

Importance of Incident Investigation

Establishes legal liability and identifies trends and statistical data.
Aims to minimize financial losses and demonstrate concern for employee welfare.
Legal requirements include compliance with MLITSD & WSIB.

Costs Associated with Incidents

Direct Costs: Medical expenses, compensation, rehabilitation, building and equipment damage, production delays, legal expenses.
Indirect Costs: Wages for lost time, hiring/training replacements, overtime, decreased productivity, loss of business goodwill.

Misconceptions of Investigation Goals

Investigations are not for exoneration of individuals, legal defenses, or assigning blame; they focus on fact-finding to prevent reoccurrence.

Incident Statistics (WSIB 2016)

Recorded 221 fatalities and over 43,000 lost-time claims.
Total WSIB payments reached $2,252,000,000.

Immediate vs. Root Causes

Immediate Causes: Apparent factors surrounding the incident.
Root Causes: Systemic issues that contribute to such incidents; addressing them can prevent future occurrences.

Factors Contributing to Incidents

Management responsibility for safety and clarity in procedures.
Inadequacies in training, supervision, and risk management.

Causation and Analysis Models

Incident Causation Model: Connects inadequate control and substandard practices to immediate causes and events leading to loss.
5 Why's Analysis: A technique to delve deeper into causes by repeatedly asking "why" until the root cause is uncovered.

PEMEP Model

Focuses on factors: People, Equipment, Material, Environment, and Process which contribute to incidents.

Ishikawa (Fishbone) Diagrams

A visual method to explore causes of accidents by categorizing potential contributing factors.

Teamwork in Root Cause Analysis

Collaborative analysis improves objectivity by incorporating diverse perspectives and experiences.

Case Study: Parking Lot Incident

Incident of a worker twisting an ankle in a pothole highlights the need for hazard identification, contributing factors analysis, and preventive measures.
Recommendations include immediate assessment and maintenance of parking lot conditions to prevent future injuries.
