The magnitude of risk for occupational exposures to biohazardous agents found in blood was assessed by 800 environmental samples taken from a total of 10 clinical and research laboratories at the National Institutes of Health (NIH). Thirty-one samples from 11 work stations in three laboratories contained hepatitis B virus surface antigen (HBsAg). Observations of workers indicated that environmental contamination arose from several sources. Among the 11 work stations with HBsAg environmental samples, eight had high work loads, seven had inappropriate behaviors, and nine had flawed laboratory techniques. This information suggests that a multifactorial approach is needed to minimize the risk of laboratory-associated infections.
通过从美国国立卫生研究院（NIH）的10个临床和研究实验室采集的800份环境样本，评估了职业接触血液中生物危害剂的风险程度。来自三个实验室11个工作站的31份样本中含有乙型肝炎病毒表面抗原（HBsAg）。对工作人员的观察表明，环境污染源于多个来源。在11个有HBsAg环境样本的工作站中，8个工作量大，7个存在不当行为，9个实验室技术存在缺陷。这些信息表明，需要采取多因素方法来尽量降低实验室相关感染的风险。
