This three day, 30-hour class was developed at the request of our clients and is based on Operator I and Operator II materials. With a focus on system operating efficiency, this course will provide a hands-on review of refrigeration fundamentals and serve as a solid foundation for the fundamental portion of the 3-year OSHA/EPA required Operator Refresher Training.

The CIRO, CARO, and CRES Exams are offered Thursday 3-6 pm after the class. As a class, we will go through the CIRO Practice Exam offered through the RETA website. This will give the student a preview of the Testing System and how to navigate the Computer and the Test.

Per OSHA Regulation 29 CFR.119(g)(2) Refresher Training. Refresher training shall be provided at least every three years, and more often if necessary, to each employee involved in operating a process to assure that the employee understands and adheres to the current operating procedures of the process. The employer, in consultation with the employees involved in operating the process, shall determine the appropriate frequency of refresher training. Please note that this class does not cover the site specific requirement of the above OSHA/EPA requirements.
