A risk assessment determines risks and dangers in workplaces by analyzing potential hazards, finding safe solutions to avoid injury or property damage, and determining if an activity can be done safely. Risk assessments are needed to assess any dangers people could face in a lab and reduce risks of harm. A risk assessment should identify possible lab dangers, guidelines for protecting people, and follow five steps: identifying hazards, deciding who could be harmed, evaluating risks and precautions, recording findings, and reviewing the assessment yearly.
