PREP | PRACTICE TEST | CERTIFICATION PREPARATION
SECTION ONE: QUESTIONS 1–100
1. What is the foundational credential required to qualify for a New Mexico Journeyman
Medical Gas endorsement?
A) ASSE 6040 Medical Gas Systems Maintenance Personnel certification
B) ASSE 6010 Medical Gas Systems Installer certification
C) NFPA 99 Medical Gas Systems Inspector certification
D) ASME IX Brazing certification alone
Correct Answer: B) ASSE 6010 Medical Gas Systems Installer certification
Rationale: New Mexico regulation explicitly requires that individuals performing medical gas
installations meet the ASSE 6010 professional qualification standard . While ASME IX brazing is a
component of the 6010 credential, it is not sufficient alone. The 6040 is for maintenance personnel,
not installers.
2. A New Mexico certified journeyman gasfitter (JG) seeks to add a medical gas endorsement.
Which of the following is the minimum training requirement mandated by state regulation?
A) 16 hours of approved medical gas training with a proctored exam
B) 24 hours of approved medical gas training with a proctored exam
C) 32 hours of approved medical gas training with a proctored exam and a brazing coupon
test
D) 40 hours of approved medical gas training with a proctored exam only
Correct Answer: C) 32 hours of approved medical gas training with a proctored exam and a brazing
coupon test
Rationale: New Mexico Administrative Code requires completion of a division-approved minimum 32-
hour medical gas and vacuum systems course meeting ASSE 6010 standards . The course has two
parts: installer training with proctored exam and a brazing coupon sent to an independent lab for
testing .
3. Which primary code establishes the minimum criteria for medical gas and vacuum systems in
healthcare facilities?
A) International Fuel Gas Code (IFGC)
B) National Fuel Gas Code (NFPA 54)
C) NFPA 99 Health Care Facilities Code
D) Uniform Plumbing Code (UPC)
Correct Answer: C) NFPA 99 Health Care Facilities Code
,Rationale: NFPA 99 is the recognized consensus standard establishing minimum criteria for medical
gas and vacuum systems in healthcare facilities . It covers performance, maintenance, installation,
and testing of nonflammable medical gas systems with operating pressures below 300 psi .
4. What is the recertification requirement for a New Mexico journeyman holding a medical gas
endorsement?
A) Annual recertification with a 4-hour course and proctored exam
B) Recertification every 3 years with an approved 8-hour course and proctored exam
C) Recertification every 2 years with a 16-hour course and proctored exam
D) No recertification is required; the endorsement is permanent
Correct Answer: B) Recertification every 3 years with an approved 8-hour course and proctored exam
Rationale: New Mexico regulation requires that journeymen with a medical gas endorsement
maintain current certification and take an approved 8-hour recertification course with a proctored
exam every three years . This requirement parallels the general JG license renewal cycle .
5. In addition to the written exam, what practical requirement must be met to obtain the ASSE
6010 Medical Gas Systems Installer certification?
A) Completion of a 40-hour supervised installation project
B) Submission of a brazing coupon to a third-party laboratory for testing
C) Verification of 500 hours of supervised medical gas installation
D) Passing a field observation by a certified verifier
Correct Answer: B) Submission of a brazing coupon to a third-party laboratory for testing
Rationale: The 32-hour course includes a brazing coupon requirement where candidates submit their
braze work to an independent third-party lab for testing . This ensures the installer can produce code-
compliant brazed joints meeting ASME IX and Chapter 13 of the New Mexico plumbing code
standards .
6. Which individuals are eligible to obtain a New Mexico journeyman medical gas
endorsement?
A) Only journeyman plumbers (JP) with 5 years of experience
B) Only journeyman gasfitters (JG) with 4 years of experience
C) Any individual who completes the 32-hour course and passes the exam
D) Properly certified journeyman plumbers (JP), journeyman gasfitters (JG), journeyman
plumber-gasfitters (JPG), or journeyman pipefitters (JPF)
Correct Answer: D) Properly certified journeyman plumbers (JP), journeyman gasfitters (JG),
journeyman plumber-gasfitters (JPG), or journeyman pipefitters (JPF)
Rationale: New Mexico Administrative Code specifies that the medical gas endorsement is issued as
an additional credential to existing journeymen in specific trades . The endorsement is not a
standalone certification; it requires a base journeyman certification in one of the four listed
categories .
7. What is the maximum apprentice-to-journeyman ratio permitted for commercial or industrial
medical gas work in New Mexico?
A) One journeyman to one unregistered apprentice
B) One journeyman to two unregistered apprentices
, C) One journeyman to three unregistered apprentices
D) One journeyman to four unregistered apprentices
Correct Answer: B) One journeyman to two unregistered apprentices
Rationale: New Mexico regulation establishes a ratio of one certified journeyman to two unregistered
apprentices on commercial or industrial work . For residential work, the ratio is one to three.
Apprentices must work under direct supervision of a certified journeyman .
8. According to ASSE 6010 requirements, how often must a credential holder verify they are still
performing qualified brazing procedures?
A) Every 3 months
B) Every 6 months
C) Every 12 months
D) Every 24 months
Correct Answer: B) Every 6 months
Rationale: The ASSE 6010 credential requires verification every six months that the holder is still
performing qualified brazing procedures in the field . Failure to maintain this verification results in
credential expiration. This ensures installers remain current with brazing skills essential for medical
gas system integrity.
9. Which type of installation is explicitly included in the scope of New Mexico's medical gas and
vacuum systems regulations?
A) Only Level I hospital installations
B) Only Level II outpatient facility installations
C) Only Level III dental office installations
D) Level I, Level II, and Level III installations including dental offices
Correct Answer: D) Level I, Level II, and Level III installations including dental offices
Rationale: New Mexico regulations apply to all individuals installing, altering, repairing, servicing,
and maintaining medical gas and vacuum systems in Level I, Level II, and Level III installations . These
systems include compressed air, piped gas, and piped vacuum systems in dental office installations .
10. What is the primary purpose of the third-party laboratory testing requirement for brazing
coupons?
A) To verify the installer can produce code-compliant brazed joints
B) To ensure the installer has completed the required training hours
C) To determine if the installer has sufficient experience in the trade
D) To certify the installer as a qualified verifier
Correct Answer: A) To verify the installer can produce code-compliant brazed joints
Rationale: Third-party laboratory testing of brazing coupons verifies that the installer can produce
brazed joints meeting the requirements of ASSE 6010 and Chapter 13 of the New Mexico plumbing
code . This is critical because medical gas system integrity depends on properly brazed connections .
11. A technician with four years of experience installing general plumbing and HVAC piping
systems is considering medical gas certification. What credential path is most appropriate?
A) ASSE 6040 only, as the technician lacks medical gas-specific experience
B) ASSE 6010, because general plumbing and mechanical piping experience qualifies
