Certification Study Tools

The CLSO and CMLSO exams are primarily based upon the ANSI Z136 Series of Laser Safety Standards. The parent document, ANSI Z136.1-2014 Safe Use of Lasers is the primary source of information for the CLSO exam. The primary source of information for the CMLSO exam is the ANSI Z136.3-2011 Safe Use of Lasers in Health Care standard.

Laser Institute of America is the publisher of the ANSI standards; these standards can be purchased from the LIA bookstore.
