Requirements for CAS®

Process safety addresses the reduction in the risk from catastrophic accidents posed by facilities that handle hazardous materials.  Audits of process safety and risk management programs provide critical assurance that such programs have been designed and implemented correctly. Consequently, it is essential that individuals who perform such audits meet a standard for competence.
