This study was conducted in nanotechnology laboratories in Tehran. A designed and validated questionnaire was used to meet the study goals. List of laboratories were provided through the Iran Nanotechnology Laboratory Network. All data were analyzed using SPSS.22. While 46.7% of the laboratories employed between 5 and 10 people on average, only 33.3% of them had a nanomaterial safety and health policy. In 80.0% of laboratories, nanomaterials were stored in labeled containers, while only 20.0% of laboratories were confident of the information on the labels. In terms of engineering controls, most laboratories had minimal controls (general ventilation and local ventilation). The laboratories also had minimal facilities in terms of personal protective equipment. As the research results indicated, the facilities for reducing and controlling exposure to hazardous substances have always been minimal in these laboratories. Most of them rely on minimal controls for various reasons, such as lack of technology, lack of funds, and lack of information. Finally, it is recommended to establish up-to-date control systems in research laboratories and ensure that appropriate personal protective equipment is provided and used properly.

这项研究是在德黑兰的纳米技术实验室进行的。设计并验证的问卷用于满足研究目标。通过伊朗纳米技术实验室网络提供了实验室清单。所有数据均使用SPSS.22分析。虽然平均有46.7％的实验室雇用5至10个人，但只有33.3％的实验室制定了纳米材料安全与健康政策。在80.0％的实验室中，纳米材料存储在有标签的容器中，而只有20.0％的实验室对标签上的信息充满信心。在工程控制方面，大多数实验室的控制最少（一般通风和局部通风）。就个人防护设备而言，实验室的设备也很少。研究结果表明，在这些实验室中，减少和控制有害物质暴露的设施一直很少。他们中的大多数人出于各种原因（例如缺乏技术，资金不足和信息不足）而依赖于最少的控制。最后，建议在研究实验室中建立最新的控制系统，并确保提供适当的个人防护设备并正确使用。
