Risk Assessment

Once a hazard has been identified, employers need to assess the hazard by the degree of risk posed to the farm’s workers or visitors – this process is typically called a risk assessment. The reason for completing a risk assessment is to help prioritize the order in which you will address these risks. The next section of this workbook will help you determine the controls to put in place to protect workers and visitors from these hazards after completing the assessment.

Risk assessment

Risk assessment – process to identify, evaluate and prioritize hazards and risks.


Hazard – any source of potential damage, harm or adverse health effects.


Risk – the chance or probability that a person will become harmed or experience an adverse health effect or that potential damage will occur, if exposed to a hazard.

When determining the degree of risk to workers, you must consider the consequence and impact of exposure (e.g. injury or illness) along with the likelihood of occurrence.

The easiest way to conduct a risk assessment is to assign a risk score to the hazard.
A risk score can be calculated using the following system:


Ask yourself the following questions when determining likelihood: has this hazard caused an incident before, either on your farm or a neighbour’s? How often has it happened? Could a similar incident happen again?

Ask yourself the following questions when determining the consequence: If an incident were to happen, what would be the outcome? Would there be a serious injury or fatality? Would it cause severe damage to equipment or property? If you know of past incidents, how serious was the outcome?

Have a look at your incident records (more on this in section 5) to help you
determine the risks associated with the hazards on your farm.

Example Assessments

Example Risk Assessment Matrix

Low Risk (1 – 2): They are risks of less significance and should be managed accordingly.

Moderate Risk (3 – 6): These risks are also significant and should be addressed following high risk items.

High Risk (8 – 16): These risks are critical risks requiring immediate attention. They must be treated as high priority.
