Requirements for a Risk Assessment (Part 1)

There are 5 basic requirements for a risk assessment.

  1. Preparation
  2. Hazard Identification
  3. Converting hazards to risks
  4. Ranking risks
  5. Evaluating effectiveness of existing controls


Step 1 – Preparation


Team members need to:

  • Understand the methods that will be used to gather information and they need to know how to assess the information.
  • They must have the ability to identify workplace hazards.
  • They must understand the difference between physical hazards, behaviour based hazards and procedural hazards.
  • Understand the hazards of energy sources in the workplace.

Obtaining process flow diagrams and site plans will be a great help in the preparation of the risk assessments. They will help you to understand the way the jobs are performed and organised as well as what type of machinery is used.

Step 2 – Identifying hazards

To systematically isolate the hazards the recommended method is to define the boundaries of the risk assessment. Define where the process that’s being assessed begins and where it ends:

  • Do an events and conditions charting. Use the existing company documents to map the theoretical geographical area of the tasks in a process.
  • Determine if there are any deviations from the documented process.
  • What is the energy sources present in the processes? Some examples of energy sources may be:
    • Mechanical
    • Electrical
    • Kinetic
    • Gravitational
    • Chemical
    • Noise

Make a list of these energy sources that you have identified and state what it is that contains these energy sources. At this stage you should not try and determine if an energy source has a potential risk, it is only about establishing the hazards for now.
