SECTION ONE: QUESTIONS 1-50
1. What is the primary purpose of the NFPA-99 Health Care Facilities Code?
,A. To regulate the architectural design of hospitals
B. To establish minimum standards for electrical wiring in residential homes
C. To define the minimum safety requirements for health care facilities
D. To provide guidelines for patient billing and insurance
🟢 Correct Answer: C. To define the minimum safety requirements for health care
facilities
🔴 Explanation: NFPA-99 establishes the minimum safety requirements to protect
patients, staff, and visitors from fire, explosion, and electrical hazards in health
care facilities.
2. According to NFPA-99, which category of medical gas system requires the
highest level of reliability and monitoring?
A. Category 1
B. Category 2
C. Category 3
D. Category 4
🟢 Correct Answer: A. Category 1
🔴 Explanation: Category 1 systems are for life support and patient care
applications where failure could cause major injury or death, thus requiring the
highest level of reliability and monitoring.
3. A medical gas alarm system must be tested how frequently to ensure proper
operation?
A. Monthly
B. Annually
C. Every 6 months
D. Every 5 years
,🟢 Correct Answer: A. Monthly
🔴 Explanation: NFPA-99 requires that medical gas alarm systems be tested at
least monthly to verify they are functioning correctly and that all signals are
received by the master alarm panel.
4. Which document governs the installation of piping for medical gases?
A. ASME B31.3
B. NFPA-70
C. NFPA-99, Chapter 5
D. ASTM E-84
🟢 Correct Answer: C. NFPA-99, Chapter 5
🔴 Explanation: Chapter 5 of NFPA-99 specifically covers gas equipment, piping,
and installation requirements for medical gases, including design, materials, and
testing.
5. What is the minimum distance required between a medical air compressor
air intake and any exhaust or vent from a combustion engine?
A. 10 feet
B. 15 feet
C. 25 feet
D. 50 feet
🟢 Correct Answer: C. 25 feet
🔴 Explanation: To prevent contamination of medical air, the intake must be at
least 25 feet from sources of exhaust or combustion engine vents.
6. In a health care facility, a "facility manager" is responsible for:
, A. Direct patient care
B. Maintaining the building's infrastructure and systems
C. Developing medical treatment plans
D. Performing surgical procedures
🟢 Correct Answer: B. Maintaining the building's infrastructure and systems
🔴 Explanation: The facility manager oversees the physical plant, including safety
systems, maintenance, and compliance with codes like NFPA-99.
7. Which color code is standard for the piping of medical vacuum systems in
the United States?
A. Yellow
B. White
C. Green
D. Black with white stripes
🟢 Correct Answer: D. Black with white stripes
🔴 Explanation: Medical vacuum piping is identified by a black background with
white lettering or striping per CGA standard C-9.
8. The maximum allowable concentration of carbon monoxide in medical air is:
A. 1 ppm
B. 5 ppm
C. 10 ppm
D. 25 ppm
🟢 Correct Answer: A. 1 ppm
🔴 Explanation: Medical air must have a carbon monoxide concentration no
greater than 1 ppm to protect patient safety during administration.
