質問 # 42
A code compliant, medical gas storage room contains a large number of different compressed gases. The gases are in 25 cu. ft. cylinders and in 250 cu. ft. cylinders. All cylinders are full. The Safety Officer completed a cylinder storage audit and discovered the room was over the maximum amount of compressed gas cylinders allowed by 140 cu. ft. Which of the following is the minimum number of 25 cu. ft. cylinders that must be removed to make the storage room code compliant?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
Overage = 140 cu. ft.
Each small cylinder = 25 cu. ft.
140 ÷ 25 = 5.6 # minimum 6 needed if rounding up. However, since the question asks for the minimum number to remove to get below the limit, removing 5 cylinders = 125 cu. ft. would still leave 15 cu. ft. over the limit. Therefore, 6 cylinders must be removed.
Correct answer = C (6), not B.
References: NFPA 99 (Health Care Facilities Code), Chapter on Medical Gas Systems.
質問 # 43
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. equipment restart after a power interruption
- B. shutdown of a 1,000-ton chiller
- C. utilizing a generator to load shed
- D. high electric heat loads
正解：A
解説：
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.

質問 # 44
In boiler operations, scale is most likely to occur
- A. on a weld above the water line.
- B. in the blowdown valve.
- C. below the water line.
- D. in the huddling chamber.
正解：C
解説：
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.

質問 # 61 
A facility has the following changes in annual operations because of a recycling program:
Landfill at $40/ton: Before 600T # After 390T
Compactor pulls at $200/pull: Before 104 # After 52
Cardboard recycling revenue at $30/ton: Before 0 # After 200T
Aluminum recycling revenue at $0.30/lb: Before 0 # After 2T
What was the gross revenue from the recycling effort?
- A. $18,000
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 - B. $6,600
- C. $6,000
- D. $7,200
正解：D
解説：
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.
