Identifying, Assessing, and Controlling Hazards

Calculate Risk Level


After selecting both the likelihood and severity ratings, see what your risk matrix determines your level of risk to be. Calculate the risk level using the risk matrix.

Low Risk
  • General: Situations or conditions that typically pose minimal threat to safety and health in the workplace.
  • Example: A small trip hazard in a low-traffic area that might cause minor bruising.
  • Action: Should be monitored for changes but may not require attention now.
Moderate Risk
  • General: Situations that present a noticeable level of potential danger, requiring attention to maintain workplace safety.
  • Example: Working with power tools without proper training, risking cuts or minor bumps and bruises.
  • Action: Requires attention and implementation of controls.
High Risk
  • General: Conditions or activities that could lead to serious injuries or illnesses, or fatalities.
  • Example: Working at heights without proper fall protection, risking severe falls.
  • Action: Requires immediate intervention to control risk before proceeding to work.
Critical Risk
  • General: The most serious category, representing situations that po se immediate and substantial threats to worker safety and health.
  • Example: Entering a confined space without proper assessment and equipment, risking asphyxiation.
  • Action: Requires immediate intervention. Work should not proceed until the risk level is significantly reduced.
