Safety evaluation for remote pit refurbishment using the pit viper

The purpose of this document is to record and evaluate the hazardous conditions associated with remote pit refurbishment using the Pit Viper. These hazardous conditions were identified during a Hazard and Operability Analysis (HAZOP). Included in the evaluation is a comparison to the hazardous conditions currently included in the Authorization Basis (AB), documented in the Hazard Analysis Database (CHG 2000c) The hazardous conditions related to the Pit Viper are correlated to similar hazardous conditions as mapped to the analyzed accidents. Finally, the controls necessary to prevent a resulting accident or to mitigate the consequences were determined during the control decision/allocation process. The results of the control allocation are listed in this document. This document is not intended to authorize the activity. It documents the results of the hazard identification process and subsequent control decision process as defined in the AB. The hazard identification/evaluation process is used to determine the adequacy of controls and whether the proposed activity is within the AB. This hazard evaluation does not constitute an accident analysis
