A risk assessment identifies hazards within a workplace like a laboratory and evaluates risks to safety. It determines the likelihood and severity of potential harm from hazards and how to minimize risks. A proper risk assessment identifies hazards, evaluates who may be harmed and how, decides on precautions through reasonable and practical means, records the findings, and reviews the assessment periodically or when new hazards emerge. The goal is to protect workers and others on the premises from injury by outlining safety guidelines and precautions for the workplace.
