SECTION 1: REGULATORY CODES & STANDARDS
OVERVIEW (20 Questions)
Q1: A hospital in California is planning a major renovation of its medical gas system. The
state has adopted NFPA 99-2021, but the 2024 edition contains significant updates to medical
air quality requirements. The hospital's administration wants to use the newer standard. Who
has the final authority to approve the use of a different edition than what is currently adopted
by the state?
A. The hospital's Chief Engineer
B. The State Fire Marshal's office
C. The Authority Having Jurisdiction (AHJ) [CORRECT]
D. The medical gas system contractor
Correct Answer: C
Rationale: NFPA 99 Section 1.3.1 establishes the Authority Having Jurisdiction (AHJ) as the
organization, office, or individual responsible for enforcing the requirements of a code or
standard. The AHJ has the power to approve equipment, materials, or installations that are
not specifically prescribed by the code. While the state adoption governs, the AHJ can
approve alternative editions or equivalencies under Section 1.4 (Equivalency).
Q2: An ASSE 6010 Installer is performing work on a Category 2 medical gas system in an
outpatient surgical center. Which of the following statements regarding certification
requirements is CORRECT?
,A. Category 2 systems do not require certified installers per NFPA 99
B. The installer must hold current ASSE 6010 certification [CORRECT]
C. ASSE 6020 Verifier certification is acceptable for installation work
D. Certification is only required for Category 1 systems
Correct Answer: B
Rationale: NFPA 99 Chapter 5 requires that personnel performing medical gas system
installation, maintenance, or verification be qualified per ASSE 6000 Series standards. ASSE
6010 certification is required for installers regardless of system category (Category 1, 2, or
3). The scope of work determines certification level, not the system category.
Q3: According to NFPA 99-2024, which of the following defines a Category 1 medical gas
system?
A. Systems serving patients who are not capable of self-preservation under emergency
conditions
B. Systems where failure would cause major injury or death of patients or caregivers
[CORRECT]
C. Systems serving patients for whom an interruption would cause discomfort but not injury
D. Systems where failure would not adversely affect patient care
Correct Answer: B
Rationale: NFPA 99 Section 3.3.21.1 defines Category 1 systems as those where failure of the
equipment or system is likely to cause major injury or death of patients, staff, or visitors.
Category 2 (Section 3.3.21.2) involves minor injury, Category 3 (Section 3.3.21.3) involves
discomfort, and Category 4 (Section 3.3.21.4) involves no impact on patient care.
Q4: A medical gas system was installed in 2015 under NFPA 99-2012 requirements. The
facility is now undergoing renovation. Which code provision applies to the existing system?
A. The existing system must be upgraded to meet current NFPA 99 requirements
B. The existing system may continue in service with AHJ approval if it does not constitute a
distinct hazard to life [CORRECT]
C. Only Category 1 systems are grandfathered; Category 2 and 3 must be updated
D. Systems over 10 years old must be completely replaced
Correct Answer: B
Rationale: NFPA 99 Section 1.5.1 (Existing Systems) permits systems installed under
previous editions to continue in service when the AHJ determines they do not constitute a
,distinct hazard to life. This is often called the "grandfather clause." However, Section 1.5.2
requires that modifications meet current edition requirements.
Q5: The Centers for Medicare & Medicaid Services (CMS) adopted NFPA 99-2012 with specific
amendments for healthcare facilities participating in Medicare/Medicaid programs. Which
statement accurately describes the CMS adoption status as of 2024?
A. CMS has adopted NFPA 99-2024 with full amendments
B. CMS continues to reference NFPA 99-2012 through the 2012 Life Safety Code adoption
[CORRECT]
C. CMS adopts the most current NFPA 99 edition automatically upon publication
D. CMS has withdrawn NFPA 99 requirements entirely
Correct Answer: B
Rationale: As of 2024, CMS continues to reference NFPA 99-2012 through its adoption of the
2012 edition of NFPA 101 (Life Safety Code) and associated healthcare facility requirements.
While CMS issued a final rule in 2021 updating fire safety standards, the medical gas system
requirements remained tied to the 2012 edition. Facilities should verify current CMS
interpretive guidelines as updates may be pending.
Q6: An ASSE 6010 Installer's certification expires in 30 days. According to ASSE 6000 Series
standards, what are the requirements for recertification?
A. Complete a 2-hour online refresher course
B. Pass a renewal examination and complete a 4-hour refresher course every 3 years
[CORRECT]
C. Submit proof of 40 hours of continuing education
D. Recertification is automatic with proof of employment
Correct Answer: B
Rationale: ASSE 6000 Series standards require renewal every three years, consisting of a
4-hour refresher course covering code updates and safety practices, followed by successful
completion of a renewal examination. Additionally, ASSE 6010 requires brazing continuity
verification every 6 months to maintain active certification status.
Q7: Which NFPA standard governs the storage, use, and handling of compressed gases in
medical applications when quantities exceed those exempted by NFPA 99?
A. NFPA 13 (Sprinkler Systems)
B. NFPA 55 (Compressed Gases and Cryogenic Fluids) [CORRECT]
, C. NFPA 70 (National Electrical Code)
D. NFPA 101 (Life Safety Code)
Correct Answer: B
Rationale: NFPA 99 Section 1.3.3 establishes the relationship with NFPA 55. When
compressed gas quantities exceed the exempt amounts in NFPA 99 Chapter 5, NFPA 55
applies. NFPA 55 provides comprehensive requirements for bulk storage, piping, and handling
of compressed gases including cryogenic fluids.
Q8: A verifier is inspecting a medical gas installation and discovers a violation of NFPA 99
requirements. The installer argues that the installation meets local building code. What is the
verifier's proper course of action?
A. Accept the local building code as equivalent
B. Document the violation and notify the AHJ [CORRECT]
C. Reject the entire system until corrected
D. Allow the installation with written waiver from the owner
Correct Answer: B
Rationale: Per NFPA 99 Section 4.6 and ASSE 6020 standards, verifiers must document all
deficiencies and report them to the appropriate authority. When conflicts exist between
codes, the most restrictive requirement applies unless the AHJ approves an equivalency. The
verifier's role is to identify non-compliance, not to approve variances.
Q9: Which of the following statements about the relationship between ASSE 6010 and ASSE
6020 certifications is CORRECT?
A. ASSE 6010 Installers may perform verification without additional certification
B. ASSE 6020 Verifiers may perform installation work under ASSE 6010 scope
C. ASSE 6010 and ASSE 6020 are distinct certifications with different knowledge and skill
requirements [CORRECT]
D. ASSE 6020 supersedes 6010; holders may perform both functions
Correct Answer: C
Rationale: ASSE 6010 (Medical Gas Systems Installer) and ASSE 6020 (Medical Gas Systems
Verifier) are separate, distinct certifications with different examination requirements,
knowledge domains, and scopes of work. Neither certification supersedes the other.
Installers cannot perform verification, and verifiers cannot perform installation work unless
separately certified.
