Lawrence Livermore National Laboratory (LLNL) and the NNSA Livermore Site Office teamed up to prepare a site specific work smart standard setting requirements for preparation of safety basis documents for LLNL non-nuclear operations and facilities. This standard documents how all hazards (biological, chemical, explosive, industrial, and radiological) shall be evaluated, classified, analyzed, and controls developed. This standard was developed to evaluate hazards at the facility level to mesh with LLNL's ISM system for reviewing hazards at the activity level. This standard presents an approach to establishing safety basis for non-nuclear operations and activities, taking a graded approach based on the potential for impacts to the health of collocated workers and the public. Direct worker safety is covered by LLNL's work activity level reviews and requirements. This standard includes streamlined mechanisms for classifying hazards based upon the unmitigated potential for human health impacts. A review or practices at several private industries, government laboratories, and DOE complex sites provided a benchmark and comparison of safety analysis processes. These approaches were compared with LLNL's existing systems, leading to a determination that facility specific safety basis documents added value to a rapid authorization for new work activities in LLNL facilities. A process for hazard classification that would be viewed as more credible than the previous facility classification system was developed, including a method allowing correlation of chemical inventories with TEEL* concentrations. A graded approach for classification of explosive hazards, consistent with the DOE Explosive Safety Manual, was included. The standard was designed to be complementary with LLNL's existing work smart standards covering the hazards identified in a facility. A standard for LLNL's Work Smart Standard set was prepared that will assure all hazards are covered with appropriate levels of analysis to provide a safety basis for non-nuclear facilities and operations. Other sites may find the overall approach a credible mechanism with a graded approach to classification and hazard and accident analysis to provide a safety basis for non-nuclear facilities and operations.
