Hazards Analysis Report Addendum Buildign 518/518A Industrial Gases & Chemtrack Receiving & Barcoding Facility

Abstract

This report documents the Hazards Analysis Report (HAR) Addendum for Buildings 518 and 518A. In summary, the description of the facility and the operations given in the 1995 PHA are the same as the present in this year 2000. The hazards description also remains the same. The hazards analysis in this HAR Addendum is different in that it needs to be compared to operations routinely ''performed'' by the public. The HAR Addendum characterizes the level of intrinsic potential hazards associated with a facility and provides the basis for hazard classification. The hazard classification determines the level of safety documentation required and the DOE order governing the safety analysis. The hazard classification also determines the level of review and approval required for the safety analysis. This facility does not contain any safety class systems or systems important to safety as defined in Department of Energy standard DOE-STD-3009-94. The hazards of primary concern associated with B518 and B518A are chemical in nature. The hazard classification is determined by comparing facility inventories of chemicals with threshold values for the various hazard classification levels. In this way, the hazard level of the facility can be ascertained. The most significant hazards that could affect people in the local area of B518 and B518A, elsewhere on the LLNL site, and off site, are associated with hazardous and toxic materials. These hazards are the focus of this report and are the basis for the facility hazard classification.
