Risk assessments (HIRA)
To address occupational hygiene issues in a consistent manner, a Hazard Identification and Risk Assessment, also known as a risk assessment or health risk assessment, is performed.
A hazard assessment investigates the employee or worker's work activities, their exposures to hazards, their responsibilities and the procedures. The occupational hygiene process is initiated when a chemical, biological or physical hazard is identified on that hazard assessment.
Following the risk assessment process, a formal method of measurement is performed by means of surveys or exposure assessment.
