In-space propellant systems safety. Volume 2: System safety guidelines and requirements

Detailed system safety guidelines/requirements were developed. Each one describes a safety measure which is suggested as a means of eliminating or reducing a particular hazard, or group of hazards, to an acceptable level, and which, if followed would tend to increase the level of safety in supplying propellants to a user in orbit. The first goal was to identify those actions that should be taken to make propellant logistics operations as safe as possible. The second was to serve as a checklist to verify that these actions had been taken in the design and operation of this and similar programs, or that they had been considered and rejected. The safety measures described in the GLR's are directed toward the prevention of hazards, the avoidance of undesired events, and the protection of the crew.
