Exam Overview

The CGA M-1 & ASSE 6015 certification exam will provide a comprehensive evaluation of a candidate’s knowledge of the process of designing, locating, installing, commissioning, maintaining, testing, removing, and documenting work on a bulk compressed medical gas (CMG) supply system in accordance with CGA M-1, Standard for Medical Gas Supply Systems at Health Care Facilities (an American National Standard), and ASSE 6015, Bulk Medical Gas Systems Installers.

The CGACB Bulk CMG Supply System Personnel Certification exam does not address:

  • piped distribution systems within the health care facility including source valve requirements;
  • fabrication of assemblies such as pressure control manifolds that are manufactured in a supplier's shop and qualified for medical gas service in accordance with the bulk CMG supply system installer’s policies;
  • manufacturing plants or other establishments operated by the supplier or the supplier’s agent for the purpose of storing and refilling portable containers, trailers, mobile supply trucks, or tank cars with medical gases;
  • non-health care facilities such as laboratories, pharmaceutical, or biotechnology facilities;
  • medical vacuum systems; or
  • supply systems that generate compressed medical gases on-site.

This is an open book exam. Candidates are encouraged to bring:

  • CGA M-1, Standard for Medical Gas Supply Systems at Health Care Facilities (4th ed.);
  • NFPA 99, Health Care Facilities Code (2018 ed.);
  • NFPA 55, Compressed Gases and Cryogenic Fluids Code (2015 ed.); and
  • 21 CFR parts 210 and 211, FDA Current Good Manufacturing Practices.

Each candidate will be permitted 2 hours to take the exam; requests for accommodation for additional time can be made when the exam is scheduled. Candidates are not permitted to share material(s) or use any electronic device during the exam.
