A Refinery Safety Overview (RSO) card is given by an authorized training center after an applicant undergoes an RSO training course. After the course, a test is administered. The applicant must get 80 percent or higher in order to pass.
An RSO course is developed to educate petrochemical workers regarding the health and safety hazards that come with working in their industry. The training course gives an overview of health regulations and safe work practices to provide guidelines regarding the maintenance of a safe working environment for both employees and their employers. The course also includes basic training concerning the prevention of work-related illnesses and injuries.
