CN Risk Management
CNs Risk Management Process 5-Steps Risk
Assessment is an important part of CNs Risk
Management Process

• Identify hazards

• Assess hazards

• Risk Control Alternatives

• Implement Controls

• Monitor

CN Risk Management
Risk Assessment Risk Analysis Risk
Evaluation

• Risk Analysis
• Identify potential hazards (what can go wrong ?)
• Potential sources
• External (ex weather)
• Management systems (ex training )
• Control Systems / Mechanical (ex wear,
  software)
• Human Factors (ex mistakes, voluntary)
• Risk Evaluation
• Quantify risks
• Risk Frequency x Consequence

5
Risk Analysis ProcessDefine the Scope

• What questions do we need to ask to define the
  scope?
• What do you want to analyze ?
• Over what geographic location (yard, zone,
  division, etc.)
• Ex. Analyze the risk of a derailment in Able
  Yard related to turning hand operated switches
  and develop measures to reduce risk.

6
IDENTIFY THE HAZARDS

• Define the task
• Define the principle steps
• Identify the potential sources of hazards
• Define the related hazards
• Identify what can go wrong

12
Risk Decisions

• How to establish appropriate controls
• Consider the risk level
• Consider risk control alternatives (ie tolerate,
  treat, terminate, transfer)
• Consider the cost/benefit (immediate and
  potential savings over time. Savings should
  generally be of 3 to 5 year payback)
• Select alternative(s) which optimize safety and
  make business sense.

13
Implement Monitoring Process

• Monitoring process will measure success of risk
  management intervention
• Monitoring processes can include
• Compliance observations
• Safety performance
• Measures of interventions (ie meetings,
  training)
• Field audits

14
Who Performs Risk Assessments?

• Supervisors
• Risk Management Officers
• Multifunctional teams with union/management

15
CN Risk Management
3 Levels of Application

• Time-critical On the run consideration of the
  5 steps
• Deliberate Application of the complete 5-step
  process
• In-depth Complete 5-step process with detailed
  analysis

16
Implementation
CN Risk Management

• Risk Management Process driven throughout
  organization
• Implementation approach

• Training
• Training Line Management on RM process
• Documentation
• Safety Management System Written procedures
• Standardized approach
• Develop Decentralized Capability
• Advanced Risk Assessment Training for key
  managers in Divisions (decentralized capability)
• Support by corporate safety group
• Selective and Progressive implementation
• Critical operational activities (ex turning
  switches)
• Process Changes (ex yard amalgamation)

17
Turning Switches example 1

• Define Scope
• Analyze injury risk only
• Location Able yard
• Population All employees
• Time frame 5 years

Potential Risk Control Strategies

• People
• Train employees on SAFE WORK PROCEDURES for
  turning switches
• Educate employees on switch inspection (prior to
  turning)
• Process
• Develop/implement Engineering Maintenance
  Schedule
• Perform Work observations and efficiency tests
• Equipment
• Install ergonomic switches at strategic locations
  (based on economics)

22
Monitoring Plan

• Verification of Engineering maintenance records
• Observations for compliance to safe work
  procedures (documented in PMRC)
• Accident Trend Analysis conducted by Risk
  Management and Workplace Safety and Health
  Committee to confirm reduction in injuries

Route Risk Assessment Example 2

• Objective
• Quantify risk level over specific route
• Minimize risk through implementation of optimal
  risk controls
• Methodology
• Probability calculated with accidents over
  specific route
• Consequence based on evacuation radius for
  product
• Risk calculated with Probability and
  Consequence.
• Benefits
• Knowledge of derailment causes and their
  proportion
• Compares effectiveness of different risk
  reduction alternatives
• Compares risk levels of different routes
• Resources can be directed at the most effective
  risk
• reduction alternatives.

25
CN Risk Management - Examples

• Route Risk Assessment (contd)
• Petroleum Train Route between Able and Barrie
• Current probability of derailment 1.6210-6
  accidents/train-mile/year
• After implementation of risk reduction
  initiatives
• P 1.1610-6 accidents/train-mile/year (-28)
• Product Diesel fuel and Gazoline.
• Risk of release  rr  (TC data) 0.36
• Population density d 623 people/0.5 mi2
• Risk R P dist. d rr 8 10-3 people
  affected
• (ie 8 people affected per 1000 train passages)

26
CN Risk Management - Examples
27
Other Examples

• Turcot/ Taschereau Consolidation
• Objectives
• Increase capacity, Improve Efficiency and Asset
  Utilization
• Risk Assessment Approach
• Multifunctional team
• Identification of potential risks for new
  operation
• Assess each potential risk
• Develop, implement, and monitor risk controls.

• Train brake testing changes
• Objectives
• Improve efficiency through parallel activities
• Improve yard and asset utilization
• Risk Assessment Approach
• Multifunctional team
• Process charts (pre/post process)
• Risk identification / assessment
• Risk controls and monitoring plan
• Pilot project to confirm expected outcome

28
Other Examples

• Injury Risk Mitigation
• Top activities causing injuries
• identified through trend analysis
• Hazards for each activity determined
• Safe Work Procedures developed
• with assistance from Health and Safety
  Committees
• Training delivered to Line Management and
  Employees
• Communication tools developed to facilitate
  training
• (videos and activity cards)
• Monitoring integrated in PMRC (Safety
  Monitoring
• Information System).

29
Success Factors
CN Risk Management

• Top-Down Commitment
• Bottom-up Awareness (Training,
• communication...)
• Organization conducive to cooperation and
• communication (Safety Culture)
• Risk Management Process Understood

30
Summary

• CN is committed to the Risk Management process
• Risk Assessment is an important element
• CN is active in anchoring the RM process
• throughout the organization
• Training, documentation, decentralized
  capability, sustained implementation
• Risk Management is a work-in-progress and CN
• is committed to continuous improvement.
