NSS 1740.12, SAFETY STANDARD FOR EXPLOSIVES, PROPELLANTS, AND PYROTECHNICS. This document prescribes the National Aeronautics and Space Administration
(NASA) safety standards/procedures for operations involving explosives handling and
processing. These operations are an integral part of explosives and explosives-related
development and manufacturing activities. Safety of all explosives 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
handling or processing.

NSS 1740.14
NSS 1740.14, NASA SAFETY STANDARD GUIDELINES AND ASSESSMENTS FOR LIMITING ORBITAL DEBRIS.
This document serves as a companion to NASA Management Instruction (NMI) 1700.8, and provides
specific guidelines and methods to comply with the NASA policy to limit orbital debris generation. The
guidelines serve to help ensure that launch vehicles, upper stages, and payloads meet acceptable standards
for limiting orbital debris generation. This document should be used by the program manager or project
manager as the primary reference in conducting debris assessments. The standard establishes guidelines
and provides supporting analysis tools for: (1) limiting the generation of orbital debris, (2) assessing the
risk of collision with existing space debris, and (3) assessing the potential of spacecraft-generated debris
fragments to impact the Earth's surface. In addition to guidelines and methods for assessment, this
volume provides formats for the debris assessment reports. Two appendices are used to define frequently
used terms and to provide summary background information.
Another document, entitled "Reference Manual for Orbital Debris Assessments," provides more in-depth
background and technical information. In addition, debris assessment software is available to support the
assessment of particular guidelines and to evaluate mitigation measures.

NSS 1740.16, SAFETY STANDARD FOR HYDROGEN AND HYDROGEN SYSTEMSIdent. Num:
NSS 1740.16
NSS 1740.16, Guidelines for Hydrogen System Design, Materials
Selection, Operations, Storage, and Transportation. This handbook is a central agency document containing guidelines for safely
storing, handling, and using hydrogen in gaseous, liquid, or slush form,
whether used as a nonpropellant or propellant. Each designer, user,
operator, maintainer, assurance person, and designated project manager is
responsible for incorporating the appropriate requirements of this guideline
document into their projects or facilities. However, use of this guideline
document does not relieve the designer, user, operator, maintainer, and
assurance person and designated managers of professional responsibility or
allow them to preclude the exercise of sound engineering judgment.
