Job Hazard Analysis Using the Risk Assessment Matrix

The following comments were adapted from “Job Hazard Analysis” by James Roughton and Nathan Crutchfield.  The video provides an example on use of the risk assessment matrix. Please review my previous blog video where I discussed the definitions of Hazard and Risk.  Also review ANSI AIHA Z10-2005, Appendix E for insights on risk assessment.

Using the Risk Assessment Matrix within the Job Hazard Analysis Process

An essential element in the establishing of a job hazard analysis process is to include both a hazard assessment and a risk assessment to set the foundation for prioritizing actions and required controls.  The Risk Assessment provides a systematic approach that allows ranking of risks.    Given budgets, available time and other organizational constraints, targeting jobs and tasks using a hazard/risk priority system aids in establishing a bias towards more effective actions.

The concept of risk must be clearly understood by managers, supervisors and employees.  Using only losses related data based on injuries and damage does not provide a full understanding and determination of where operational hazards may exist but have not as yet created a tangible loss.

When conducting a risk assessment, one must understand what constitutes unnecessary risk. Accepting risk is a function of both risk assessment and risk management and is not as simple a matter as it first appears. Several principles apply:

  • A degree of risk is a fundamental reality of life. Hazards of various strengths will exist and realistically some level of risk must always be accepted.
  • Risk must be understood for effective Job Hazard Analysis
  • It is critical that no risk should be accepted without a full understanding of the consequences of an exposure.
  • To effectively establish risk control priorities, potential relevant business and social considerations must be included.   These may include, but ot be limited to: the different types of impacts on the business; prejudgments; individual perceptions of the feasibility for reducing or avoiding risks; the impact on quality of life and environment; and the magnitude and distribution of both short and long term benefits.

After the consequences of hazard exposures are understood,  defining the severity and probability factors for job steps and tasks is completed using a risk matrix. The risk within each step and task can then be incorporated into the Job Hazard Analysis.
