    OSHA Technical Support System (OTSS)

    Metadata Updated: January 20, 2026

    The OSHA Technical Support System (OTSS) replaces LISA and TESA to serve as the main database for the collection of sampling and analytical results produced during the laboratory analysis of chemical samples and to record, store, track and make available to OSHA personnel, and technical information pertaining to OSHA’s equipment servicing, which most often includes calibration measurements. The database directly supports laboratory processes in which sampling and analytical results are generated, processed, and distributed to OSHA field personnel as well as equipment ordering/servicing and agency consumable supply ordering related to field office technical support.
