Root Cause Description

  • The root cause of any accident/incidents is the most basic cause that can reasonably be identified and management had the control to fix.

    Root Cause Analysis will;

    Identify the system that failed;
    Map the system to causation;
    Identify the management failure;
    Identify the root cause.

    There are usually only Four Possibilities:

    1. No system in place;
    2. There is a system however, the System is poorly defined;
    3. The defined System is adequate but was not correctly implemented;
    4. System defined but not implemented at all.

Investigation Process

  • Once notification of an accident or incident is received you are ready to undertake an investigation, the purpose of the investigation should be to;

    a) Identify the system which failed;
    b) Examine the system for problems;
    c) Identify the root cause of the accident/incident.

    You can use the checklist below as you go about your investigation.

  • Investigation Process Checklist

  • Collect Initial Data

  • Collect Information about management systems.

  • Collect information regarding Physical Controls.

  • Collect information regarding behaviours.

  • Examine worksite.

  • Identify personnel involved.

  • Identify equipment involved.

  • Interview Staff/Witnesses.

  • Examine documentation.

  • Examine training records.

  • Examine Health & Safety inspection reports.

  • Conduct any required tests.

  • Notes


  • Here you need to Depict Events using the five "W's" = (who, what, why, where, when) and identify the following;

  • Causal Factors

  • Factual Evidence

  • Add media if relevant.

  • Relationships

  • Develop an Events & Causation chart using recognised technique.

    eg - fish bone, fault tree, FMEA etc.

  • Draw Chart

  • Get chart

  • Identify system which failed.

  • Examine the system for problems.

Management Controls

  • Policy

  • Was a Policy in place?

  • Was the policy adequate?<br>

  • Planning

  • Was there a plan in place?

  • Was the plan implemented?

  • Was the plan adequate?

  • Control

  • Who is responsible for the standard?

  • Was it in accordance with the standard?

  • Was the responsibility re-assigned?

  • Who to?

  • Competence

  • Is there a required standard?

  • Was the standard adequate?

  • Was the person/person competent?

  • Why was the person not competent?

  • Implementation

  • Was the system specified?

  • Was the system adequate?

  • Was the system implemented?

  • Was the system implemented to the required standard?<br>

  • Communication

  • Was the system communicated?

  • Was the communication adequate?

  • Was it in line with the standard?

  • Cooperation

  • Was a standard specified?

  • Was it adiquate?

  • Was there cooperation?

  • Measuring

  • Was there a standard for measuring the system?

  • Was it effective?

  • Were the measures in line with the standard?

  • Reviewing

  • Was there a system for reviewing?

  • Was the system for reviewing adequate?

  • Was the system reviewed?

  • Were any reviews in line with the standard?

  • Were any reviews in line with the standard?

Root Cause

  • Root Cause

    Remember The root cause is the most basic cause that can reasonably be identified and management had the control to fix.

  • No system in place. There is nothing in place to address this particular risk.

  • System is adequate but not correctly implemented. There is a system defined, but this is not what was implemented.

  • System is poorly defined. The system to address the risk has been implemented but it is poorly conceived.

  • System defined but not implemented at all. There is a system defined but has not been implemented at all.

  • This assumes that a system is adequately defined in the first place and if it had been implemented properly then it will not be the root cause.

  • Conclusion

  • Investigation concluded.
