This is NASA Procedural Requirements (NPR) 8715.3D which establishes NASA's General Safety Program Requirements, effective December 16, 2021 through December 21, 2026. The document defines NASA's roles and responsibilities for assuring safety and mission success, with mandatory compliance required for NASA employees.

The NPR outlines comprehensive safety requirements across several key areas including programmatic safety, system safety, and contractor safety management. It establishes a three-tier project priority ranking system based on human safety/health implications and mission criticality, with corresponding levels of safety analysis required. Key provisions include requirements for hazard analysis, risk assessment, safety modeling, safety documentation, and review processes. The document specifies that contractors must be included in NASA's Safety Program, with requirements for safety risk assessments before hazardous work. Multiple chapters covering operational safety, aviation safety, fire safety, facility safety and personnel certification were cancelled by NPR 8715.1B, with those requirements now covered in other NASA documents. The document includes detailed definitions and acronyms but reserves several appendices including those related to safety motivation/awards, radioactive material limits, and sample safety plans.
