Project Summary Phosgene is essential to the manufacturing of products used in everyday life such as flexible foams, thermoplastic polyurethane, and sealants and elastomers. It is also a building block for many plastics, pesticides, and pharmaceuticals. However, at room temperature phosgene is an extremely toxic, colorless gas—exposure can cause immediate symptoms of eye and skin irritation, and symptoms of respiratory distress such as coughing, tightness in the chest, difficulty breathing, pneumonia, or heart failure that may not manifest until 6-24 hours after exposure. Therefore, phosgene-producing facilities need large phosgene detectors for wide-area monitoring, as well as phosgene indicator badges for monitoring individuals. Electrochemical detectors perform real-time monitoring with audio alarms for phosgene exposure, but they are expensive and can only be installed in limited locations. A wearable colorimetric indicator badge is the standard means of monitoring individuals. It indicates the presence of phosgene by changing color, but the disadvantage is that the worker must constantly look at the badge to ensure their personal safety because it does not actively alert them to danger. Intelligent Optical Systems, Inc. (IOS) proposes to develop a low SWaP (size, weight, and power), low-cost wearable phosgene sensor for individuals that will incorporate a highly selective colorimetric phosgene sensor film with a highly sensitive optical readout unit that will trigger an audible alarm when the worker is exposed to phosgene levels that exceed a set threshold.

项目摘要 光气对制造日常生活中使用的产品是必不可少的，如柔性泡沫、热塑性塑料 聚亚安酯、密封胶和弹性体。它也是许多塑料、杀虫剂和 制药公司。然而，在室温下，光气是一种剧毒的无色气体，暴露在空气中可以 引起眼睛和皮肤刺激的即时症状，以及咳嗽等呼吸窘迫症状， 胸闷、呼吸困难、肺炎或心力衰竭，可能要到6-24小时后才能表现出来 曝光。因此，光气生产设施需要大型光气探测器进行广域监测，因为 以及用于监测个人的光气指示器徽章。电化学检测器实时执行 使用音频报警器监测光气暴露，但它们价格昂贵，只能有限地安装 地点。可佩戴的比色指示器徽章是监测个人的标准手段。它表明 光气的存在通过改变颜色，但缺点是工人必须不断地观察 佩戴徽章以确保他们的人身安全，因为它不会主动提醒他们危险。智能光学系统， 公司(IOS)计划开发一种低交换(尺寸、重量和功率)、低成本的可穿戴光气传感器，用于 将高选择性比色光气感应器薄膜与高灵敏度 当工人暴露在超过光气水平时，将触发声音警报的光学读出装置 设定的门槛。
