SECTION 1: Codes, Standards, & Definitions
Q1: Per NFPA 99-2024, what is the minimum required pressure for a
medical air outlet at the most remote point of use?
A. 40 psig
B. 50 psig
C. 55 psig
D. 60 psig
Correct Answer: C
Rationale: Code Citation: NFPA 99 (2024), Section 5.1.9.1.2 mandates ≥
55 psig at the most remote outlet to ensure pneumatic devices function.
Distractor Analysis: 40 psig (A) and 50 psig (B) are sub-code and risk
ventilator alarms; 60 psig (D) is acceptable but not the stated minimum.
Q2: Which ASSE 6000 series standard governs the qualifications of
individuals who perform medical gas system verifications?
A. ASSE 6010
B. ASSE 6030
C. ASSE 6040
D. ASSE 6050
Correct Answer: B
Rationale: Code Citation: ASSE 6030 (2023) specifically covers
“Medical Gas Systems Verifiers.” Distractor Analysis: 6010 (A) is for
installers, 6040 (C) is for maintenance personnel, and 6050 (D) is for
instructors.

Q3: CGA Pamphlet C-9 requires that the station outlet label for nitrous
oxide include which two identifiers?
A. “N₂O” and green background
B. “NITROUS OXIDE” and blue background
C. “N₂O” and yellow background
D. “NITROUS OXIDE” and green background
Correct Answer: B
Rationale: Code Citation: CGA C-9 (2022) mandates full name
“NITROUS OXIDE” and blue color-coding. Distractor Analysis: Green
(A, D) is oxygen; yellow (C) is medical air; omitting full name (A, C)
violates labeling clarity.
Q4: NFPA 99 classifies a hospital Category 1 space as one in which
failure of medical gas would:
A. Cause minor discomfort
B. Cause major injury or death
C. Result in economic loss only
D. Require 24 h repair window
Correct Answer: B
Rationale: Code Citation: NFPA 99 (2024), Section 4.1. Category 1 is
defined as failure “likely to cause major injury or death.” Distractors
describe Category 2 (A), Category 3 (C), and no such repair window
(D).
Q5: What is the maximum allowable concentration of hydrocarbon (as
methane) in medical air per USP monograph?
A. 1 ppm
B. 25 ppm
C. 100 ppm
D. 500 ppm
Correct Answer: B
Rationale: Code Citation: USP-NF Medical Air monograph (2025) sets ≤
25 ppm total hydrocarbons expressed as methane. Distractor Analysis: 1
ppm (A) is oxygen purity level; 100 ppm (C) and 500 ppm (D) exceed
pharmacopeia limits.
