For large industrial and research operations, maintaining reasonable control of all toxic materials used in their operations can be a formidable task. A system utilizing cards has been developed which serves a dual purpose, informing the user regarding hazards of a particular material and also facilitating appropriate workplace surveillance during its use. Selected hazard data and spill notification message, if applicable, are printed on the card. The card contains a label which the user detaches and affixes to the container. This label classifies the material according to toxicity, flammability, reactivity, special properties on a 0 through 4 hazard rating, and spill message if needed to comply with environmental requirements.
对于大型工业和研究机构而言，对其操作过程中使用的所有有毒材料进行合理管控可能是一项艰巨的任务。现已开发出一种使用卡片的系统，该系统具有双重用途，既向使用者告知特定材料的危害，又便于在其使用过程中进行适当的工作场所监测。所选的危害数据以及适用时的泄漏通知信息会印在卡片上。卡片上有一个标签，使用者将其撕下并贴在容器上。该标签根据毒性、易燃性、反应活性、特殊性质将材料按0至4的危害等级进行分类，必要时还会包含泄漏信息以符合环境要求。
