The applicant shall be required to take a written examination testing the applicant’s knowledge of the gas fitting regulations. If a passing grade of at least 75% is achieved, the applicant will be qualified as a “Journeyman Gas Fitter”. In lieu of the above testing requirements, a Master Gas Fitter license or a Journeyman Gas Fitter license may be issued to an applicant:who has passed an examination, given by a county or municipality in the State of Maryland, which the Board deems requires the same degree of competency, skill and achievement in the gas fitting field that is required by Baltimore City; and who has an active license issued by the examining county or municipality and furnishes written verification from the county or municipality that he or she has been actively engaged in business for not less than 1 year immediately prior to the date of filing said application; and the county or municipality reciprocates by issuing licenses of a similar class to licensed gas fitters of Baltimore City, authorizing such licensees to do the same type of work within that county or municipality.
