M.O.S.T. and Common Arc

Mobilization Stabilization Optimization Training

The M.O.S.T. Program: Safety Training, Drug Screening, and Journeyman Upgrade Courses.

M.O.S.T. was established in 1989 as a joint labor trust fund by the International Brotherhood of Boilermakers (IBB) and the National Association of Construction Boilermaker Employers (NACBE).

The purposes of M.O.S.T. are to maintain a highly skilled workforce, to maintain current skills and develop new skills and technology, to instruct and teach safe work habits, not only for Boilermakers, but for all who are involved on a project, and to help provide a drug free work place.


M.O.S.T. is a national Boilermaker program being used everywhere in the United States by the Boilermakers. The M.O.S.T. program is divided into six categories: Safety Training, Drug Screening, Reserve Center (for project manning), Prescription Safety Glasses, Medical Screening, and Common Arc (for certification of welders).
