Important Information if you Employ or Plan to Employ an Apprentice

A Refrigeration Apprentice must be licensed with the OPSI, must hold a valid registration with the Division of Apprentice Standards, and must be employed by a Massachusetts Refrigeration Contractor for the duration of their apprenticeship. A Refrigeration Technician can supervise the work of the Refrigeration Apprentice, but the work hours will only be accepted while registered with the DAS, licensed with the OPSI, and under the employment of the Refrigeration Contractor.
