CHFM Exam Dumps : Certified Health Care Facility Manager (CHFM)

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.

Per NFPA 101: Life Safety Code, soiled linen and trash containers greater than 32 gallons are not permitted in patient rooms or at nurse stations. Containers larger than this must be located in designated hazardous areas with proper fire protection.

C. 32 gal. (Correct).

Smaller values (8, 16) are permissible but not the regulatory maximum.

D. 64 gal.: Exceeds NFPA maximum and requires special room design.

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.
