Abstract:The Hazardous Materials Information System (HMIS) is used to manage data required for the use, transportation, storage and disposal of hazardous material by the US Government. In response to concerns expressed by some users, DORO was tasked to conduct an independent review of data quality. An analysis of 43 mandatory fields in 250 sample records showed a 4.6% field error rate for newer records, and over half the records had one or more errors. The review of 366 sample records in ten commodity groups showed generally high data consistency for records within each group, but areas of weakness were observed. HMIS has experienced problems in system evolution, different business practices at the major focal points, a wide variety of input formats and different interpretations of regulatory guidance. Despite the study findings, HMIS is a valuable resource for users. The study identified a number of areas that are candidates for corrective action, and made recommendations to improve current and future HMIS data quality.
