NPR 8715.1B Effective Date: February 01, 2021 Expiration Date: February 01, 2026

Subject: NASA Safety and Health Programs

Responsible Office: Office of Safety and Mission Assurance

Chapter 12. Mission Collateral Safety Risk

12.1 Overview

Missions expose the public, the workforce, and Earth, space, and planetary environments to risk associated with conducting the missions. This chapter addresses functional areas directly tied to missions. These are range flight safety, payload safety, nuclear flight safety, and flight pressure vessels.

12.2 Range Flight Safety

NASA roles, responsibilities, and procedural requirements for protecting the public, workforce, and property during range operations associated with flight are documented in NPR 8715.5, Range Flight Safety Program. These roles include the Center Range Flight Safety Lead.

12.3 Payload Safety

NASA roles, responsibilities, and procedural requirements for protecting the public, workforce, and property during payload ground operations associated with processing and testing, vehicle integration, flight, and planned return-to-Earth recovery and sample return are documented in NPR 8715.7, Payload Safety Program. These roles include the NASA Payload Safety Manager.

12.4 Nuclear Flight Safety

NASA roles, responsibilities, and procedural requirements for protecting the workforce, public, and the environment from risks associated with a planned launch of radioactive materials into space, on launch vehicles and spacecraft are documented in NPR 8715.3, NASA General Safety Program Requirements. These roles include the Chief, SMA and the Nuclear Flight Safety Assurance Manager.

12.5 Flight Pressure Vessels and Pressurized Systems Safety

12.5.1 Managers of space and atmospheric programs and projects shall designate an individual to establish and manage a qualification and acceptance or recertification process to ensure safe and reliable testing and use of space and atmospheric-flight PVS.

12.5.2 Centers and Mission Directorates shall qualify and accept spaceflight PVS, including qualification units, in accordance with ANSI/AIAA S-080A-2018, Space Systems—Metallic Pressure Vessels, Pressurized Structures, and Pressure Components, and ANSI/AIAA S-081B-2018, Space Systems—Composite Overwrapped Pressure Vessels (COPV).

12.5.3 All handling of COPVs shall be in accordance with their damage control plan.

12.5.4 Centers and Mission Directorates shall qualify and accept atmospheric flight (non-spaceflight) PVS in accordance with the Federal Aviation Administration, in Hazardous Materials Regulation, 49 CFR subch. C. Aircraft PVS on NASA operated aircraft, owned by other agencies such as the Department of Defense, will be maintained, operated, and modified in accordance with approved technical orders from the agency owning the aircraft.
