Question No : 2

What is the required fire rating of a door in a 2-hour rated wall assembly?

A.1/2 hour
B.1 hour
C.1 1/2 hours
D.2 hours

정답:
Explanation:
NFPA opening-protective tables specify that doors protecting openings in 2-hour fire-resistance-rated fire barriers are required to have a 1-1/2-hour (90-minute) fire protection rating. This distinction between the wall’ s fire-resistance rating and the door’s fire-protection rating is standard in NFPA 101 and NFPA 80.

Question No : 3

Which of the following must be considered at the schematic design stage?

A.lighting fixtures
B.egress requirements
C.general conditions
D.equipment specifications

정답:
Explanation:
In the schematic design phase, the design team establishes overall building configuration, circulation, and code-driven life safety concepts, including means of egress. Life Safety Code requirements (occupant loads, exit access, number and arrangement of exits, travel distances) are fundamental constraints that shape the plan early; they must be set before moving into design development where specific fixtures and detailed equipment specifications are finalized. Contract “general conditions” are part of procurement/contract documents later, not schematic design.

Question No : 4

A measured carbon dioxide level of 1,500 ppm in an area of a facility may indicate

A.air exchange rates are within design.
B.vehicular exhaust entering the area.
C.lack of outside air.
D.humidity/dewpoint problems.

정답:
Explanation:
Acceptable indoor CO# concentrations in healthcare facilities are generally expected to remain below 1,000 ppm, as recommended by ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality). A reading of 1,500 ppm typically signals inadequate ventilation and insufficient outside air being introduced into the space. This is a direct indicator of poor dilution of indoor contaminants.
Correct: Lack of outside air (C) C High CO# concentrations are directly linked to reduced outside air supply.
Incorrect:
A. Within design C Not correct, since 1,500 ppm exceeds design thresholds.
B. Vehicular exhaust C Would raise CO and NOx levels, not primarily CO#.
D. Humidity/dewpoint C Unrelated to CO# measurement.

Question No : 5

According to NFPA 13, when replacing standard response sprinkler heads with quick response heads, all heads must be replaced in the entire

A.compartment.
B.zone.
C.building.
D.corridor.

정답:
Explanation:
NFPA 13 (Standard for the Installation of Sprinkler Systems) specifies that quick-response and standard-response sprinklers shall not be mixed within the same compartment. This is to ensure uniformity in activation and discharge characteristics.
A (Compartment): Correct, all heads in a compartment must match type.
B, C, D: NFPA does not require wholesale replacement across zones, buildings, or corridors beyond the compartment.
References: NFPA 13, Section 8.3.3.3.

Question No : 6

According to NFPA 70, what is the minimum working clearance required for enclosed electrical equipment with 600 volts or less?

A.18 in.
B.24 in.
C.36 in.
D.48 in.

정답:
Explanation:
NFPA 70 (NEC) Article 110.26(A)(1) establishes the depth of working space in front of electrical equipment. For systems 0C150 volts to ground, the minimum depth is 3 ft (36 in.); for 151C600 volts, the required depth is 3C4 ft depending on the condition (exposed live parts and grounded surfaces). In healthcare facilities, unless a more stringent “condition” applies, the baseline minimum clearance encountered for 600 V or less is 36 inches.

Question No : 7

A high kW demand on a facility electrical consumption report is noted for a one-hour interval. Consumption is less than normal for the same interval.
Which of the following could be the cause?

A.high electric heat loads
B.utilizing a generator to load shed
C.equipment restart after a power interruption
D.shutdown of a 1,000-ton chiller

정답:
Explanation:
A demand spike (kW) can occur when multiple large motors or systems restart simultaneously after a power interruption. Although energy consumption (kWh) over the interval may be less, the instantaneous demand registers higher because of inrush currents during restart. This aligns with CHFM exam energy management principles.

Question No : 8

Which of the following items are allowed to remain in the corridor in an inpatient care area?

A.laundry hampers
B.work stations on wheels (WOWs)
C.recycle bins
D.crash carts

정답:
Explanation:
According to NFPA 101 Life Safety Code and CMS/TJC corridor obstruction guidance, only certain items deemed essential for immediate patient care may be left unattended in inpatient care corridors. Crash carts are specifically allowed because they are emergency life-saving equipment. Other items, such as hampers, WOWs, and bins, are considered obstructions and must be removed when not in active use.

Question No : 9

Fire drills in healthcare occupancies shall include the

A.evacuation of bedridden and infirmed patients to the adjacent smoke compartment.
B.transmission of a fire alarm signal and audible alarms on each shift.
C.transmission of the fire alarm signal and simulation of emergency fire conditions.
D.evacuation of patients to areas of refuge and evacuation of staff from the building.

정답:
Explanation:
NFPA 101 (Life Safety Code, Chapter 18/19.7.1.4) requires healthcare fire drills to include transmission of the fire alarm signal and a simulation of emergency fire conditions, ensuring staff are trained to carry out emergency duties. Full evacuation of patients is not required during drills.
References: NFPA 101, Sections 18/19.7.1.4; The Joint Commission EOC standards.

Question No : 10

The occupants of a building wing complain of nausea, dizziness, or drowsiness.
Which of the following is the most likely cause?

A.mercury spill
B.humidity levels
C.insufficient outside air
D.medical gas leak

정답:
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Symptoms such as nausea, dizziness, headaches, and drowsiness are commonly associated with poor indoor air quality (IAQ). The most likely cause in this case is insufficient outside air ventilation, which allows buildup of carbon dioxide and other indoor contaminants.
Correct Answer (C. insufficient outside air): According to ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality) and referenced in NFPA 99 Health Care Facilities Code, inadequate outside air results in occupant discomfort and health complaints known as “sick building syndrome.”
Incorrect Options:
A. mercury spill: Causes more acute, localized toxic exposure symptoms; less likely across an entire wing unless a large spill occurred (and it would be unusual in general occupancy areas).
B. humidity levels: Low or high humidity can cause discomfort, but not typically dizziness or drowsiness.
D. medical gas leak: Could cause similar symptoms depending on the gas, but would typically trigger alarms and affect specific zones tied to gas lines, not general wing-wide complaints.
Relevance to CHFM:
This question relates to the Compliance and Maintenance & Operations domains. CHFM professionals must ensure compliance with ventilation codes (ASHRAE 62.1, NFPA 99, Joint Commission EC standards) and manage HVAC systems to maintain proper indoor air quality, protecting patient and staff health.

Question No : 11

Which of the following is required for airborne infection isolation rooms?

A.HEPA filter recirculation unit with UV light
B.minimum of 20 air changes per hour
C.anteroom with an area for handwashing
D.visual mechanism to monitor room pressure

정답:
Explanation:
Per CDC Guidelines and ASHRAE/FGI requirements adopted into NFPA 99, airborne infection isolation (AII) rooms must maintain negative pressure relative to adjacent areas and provide a visual pressure monitoring mechanism (e.g., manometer, electronic monitor).
A: HEPA/UV is supplemental, not a universal requirement.
B: Minimum is 12 air changes per hour, not 20.
C: Anterooms may be provided but are not universally required.
References: CDC, Guidelines for Environmental Infection Control in Health-Care Facilities; FGI Guidelines for Design and Construction of Hospitals; NFPA 99.

Question No : 12

In boiler operations, scale is most likely to occur

A.in the huddling chamber.
B.below the water line.
C.on a weld above the water line.
D.in the blowdown valve.

정답:
Explanation:
Scale forms where water is in direct contact with heated surfaces. In steam boilers, that location is below the water line, where dissolved minerals (calcium, magnesium, silica) precipitate and adhere to heat-transfer surfaces as scale. This reduces efficiency and can cause overheating of boiler tubes.
B. below the water line (Correct): Primary area where water meets heat-transfer surfaces; mineral deposits form here.
A. huddling chamber: This is part of a safety relief valve, not a surface for scale buildup.
C. weld above the water line: There is no continuous water exposure above the water line, so scale does not accumulate there.
D. blowdown valve: This is used to remove sludge/sediment, not a typical location for scale accumulation.

Question No : 13

At the end of an 8-hour electrical shutdown, after the maintenance work is completed but before the cabinets are closed up or the system re-energized, a final inspection should be completed by individuals who have

A.been involved since the beginning of the shutdown.
B."fresh eyes" and go/no go authority.
C.working knowledge of the generators and switch gear.
D.gathered feedback and attended the lessons learned debriefing.

정답:
Explanation:
Best practice in safety and risk management is to have a final inspection performed by individuals with “fresh eyes” and go/no-go authority. Those directly involved may overlook issues due to task familiarity. Independent inspection reduces risk before re-energization.

Question No : 14

According to The Joint Commission Emergency Management Standards, a facility must

A.maintain inventories of critical supplies in sufficient quantities to maintain operations for 96 hours.
B.provide utilities, equipment, and supplies in order to maintain operations for 96 hours.
C.establish agreements with utility, equipment, and supply vendors to provide support in order to maintain operations for 96 hours.
D.evaluate capabilities and response efforts for the organization to maintain operations for 96 hours.

정답:
Explanation:
The Joint Commission Emergency Management Standards require organizations to evaluate their capabilities and plan for how they would maintain operations during an emergency for up to 96 hours. This does not mandate stockpiling or guaranteeing resources for that duration, but rather ensuring that the facility has assessed its resources, strategies, and agreements to maintain patient care and safety during prolonged emergency conditions.
Incorrect Options:
A and B: Maintaining actual supplies/utilities for 96 hours is not specifically required.
C: Agreements with vendors may be part of the plan but are not the mandated standard. References:
The Joint Commission: Emergency Management (EM) Standards C 96-hour sustainment requirement.
AHA/ASHE CHFM Review Materials C Compliance domain: Emergency preparedness and response.
CHFM Candidate Handbook C Compliance domain outlines emergency management as a tested area.

Question No : 15

A facility has the following changes in annual operations because of a recycling program:

What was the gross revenue from the recycling effort?

A.$6,000
B.$6,600
C.$7,200
D.$18,000

정답:
Explanation:
Step-by-Step Calculation:
Cardboard recycling revenue:
200 tons × $30/ton = $6,000
Aluminum recycling revenue:
2 tons × 2,000 lbs/ton = 4,000 lbs
4,000 lbs × $0.30/lb = $1,200
Total Gross Revenue:
$6,000 + $1,200 = $7,200
The CHFM exam Financial Management domain requires knowledge of cost savings and revenue generation calculations from operational changes such as recycling initiatives. In this example, gross revenue is calculated by summing the total recycling income streams (cardboard and aluminum).
Correct Answer (C. $7,200): Derived from combining $6,000 (cardboard) and $1,200 (aluminum) revenue.
Other options are incorrect because:
A ($6,000): Considers cardboard only.
B ($6,600): Misapplies aluminum tonnage conversion.
D ($18,000): Exaggerates revenue beyond calculated amounts.
