Which scenario aligns with the third Nuclear Weapons Safety Standard?

The third Nuclear Weapons Safety Standard focuses specifically on preventing the inadvertent launch of nuclear weapons, particularly in abnormal environments. This standard is crucial because it addresses the potential risks associated with unintended actions or incidents that could lead to the deployment of nuclear weapons. Inadvertent launches can occur due to various factors, including technical failures, human error, or unexpected situations that compromise safety protocols.

By emphasizing the need for safeguards and procedures that ensure nuclear weapons remain secure and cannot be launched without proper authorization, this standard seeks to mitigate the associated risks to national and global security. The focus is about maintaining strict control measures and layered defenses to prevent any chance of unintended engagement or operational mishaps, which is central to the safe handling and management of nuclear arsenals.
