DSS-SOC
In 1982, five divers lost their lives when a vacuum was inadvertently drawn onboard USS GRAYBACK (SSG 574). This accident was the results of operator error, faulty equipment and an inadequate design. This led to redesign of diving systems to ensure a vacuum could not be drawn. It also led to requiring safety analysis during design for all systems and certification of all material within the Scope of Certification (SOC).
