Personnel Access Safety System
This paper describes the method and system used to control personnel accesses into hazardous areas at the Superconducting Super Collider. Hazards encountered are electrical (high voltage and high current), radiation (ionizing), cryogenic fluids (liquid helium and nitrogen), flammable gases, and ultra high magnetic fields. Although these are a diverse group of hazards, virtually all can be mitigated by controlling accesses into the hazardous enclosures. The Personnel Access Safety System (PASS) is used for this purpose. The system is comprised of dual redundant Programmable Logic Controllers (PLC) using loo2 voting (either system can bring the system down to a safe state). Numerous safety related hardware and software features have been built into this system to assure high reliability and availability.
