It is the duty of the employer to conduct a risk assessment for all tasks where an employee is exposed to ergonomic risks. The risk assessment may be carried out by an employee who is familiar with the task, provided they have the competency to do so. Before an employee conducts the risk assessment, it is the responsibility of the employer to ensure that the individual has the adequate level of competence to conduct the risk assessment. The employer may require a health and safety professional who has to demonstrate appropriate competence to conduct the risk assessment when the task being carried out is complex. While one individual may be able to carry out a risk assessment, it may be beneficial to draw on the knowledge and competencies of others.

The risk assessment should include at least the following steps:

The risk assessment should be conducted and or reviewed at least every two years and recorded. Shorter review periods may be necessary if new information becomes available or there has been a change in task or control measures. The risk assessment should also be reviewed if a reportable incident occurs or if an employee suffers an adverse health effect as a result of exposure to ergonomic risks.
