Halfway through the Sustainable Development Goal (SDG) period, there has been little research on the criteria for monitoring safely managed sanitation under SDG target 6.2. For reporting against SDGs, global indicators are necessarily limited and exclude many safety aspects from a public health perspective. Primary survey data from 31,784 households in seven countries in Asia and Africa were analysed, comparing estimates of safely managed on-site sanitation based on global indicators with five complementary indicators of safety: animal access to excreta, groundwater contamination, overdue emptying, entering containments to empty and inadequate protection during emptying. Application of additional criteria reduced the population with safely managed sanitation by 0.4-35% for specific indicators, with the largest impact due to the risk of groundwater contamination, animal access, and containments overdue for emptying. Combining these indicators across the service chain, excluding transport and treatment, found almost three-quarters of on-site systems currently assessed as safely managed with global indicators were considered unsafe based on complementary indicators. A more comprehensive assessment of safety of on-site sanitation can be achieved through these indicators, which could be integrated into national monitoring systems and used to inform sanitation investments that address local health-related risks.
在可持续发展目标（SDG）实施期过半之际，针对可持续发展目标6.2中安全管理卫生设施监测标准的研究甚少。就可持续发展目标报告而言，全球指标必然有限，且从公共卫生角度排除了许多安全方面。分析了来自亚洲和非洲七个国家31784户家庭的初步调查数据，将基于全球指标的安全管理现场卫生设施估计值与五个安全补充指标进行了比较：动物接触排泄物、地下水污染、排空逾期、进入容器排空以及排空期间保护不足。应用额外标准使特定指标的安全管理卫生设施人口减少了0.4%至35%，其中地下水污染风险、动物接触和排空逾期造成的影响最大。将这些指标贯穿服务链（不包括运输和处理），发现目前根据全球指标评估为安全管理的现场系统中，近四分之三根据补充指标被认为不安全。通过这些指标可以对现场卫生设施的安全性进行更全面的评估，这些指标可纳入国家监测系统，并用于为应对当地健康相关风险的卫生投资提供信息。
