Risk assessments identify hazards in the workplace that could harm employees or visitors. They examine what could cause injury or illness and aim to prevent harm. It is a legal requirement for employers to conduct risk assessments and involve employees. Common risks include hazards from equipment, substances, or work processes. The assessment process involves five steps - identifying hazards, evaluating risks, recording findings, and reviewing assessments periodically or when work practices change. The goal is to promote a safety culture and reduce the likelihood of claims by protecting worker health.
