Whether you want to transform your workplace or your career, the COSS course is the most effective method for the safety practitioner to achieve both.

Each class has a mix of non-experienced, first-time safety personnel as well as safety professionals who have been in the safety field for over 20 years. Regardless of the number of years of experience you have in safety, everyone leaves the COSS class with a wealth of knowledge!
