This document prescribes the National Aeronautics

48、and Space Administration (NASA) safety standards/procedures for operations involving explosives handling and processing. These operations are an integral part of explosives-related development and manufacturing activities. Safety of all explosive operations associated with NASA programs is an ongoing, primary concern and continually must be given high priority in all program direction and management. This document provides a uniform set of standards for all NASA installations involved in explosives storage, handling, or processi
