CHFM CHFM - Certified Healthcare Facility Manager Maintenance and Operations 2 — Questions and Answers
Question 1: What is the primary purpose of a preventive maintenance (PM) program in a healthcare facility?
- To perform scheduled maintenance before failure occurs, reducing unplanned downtime and extending equipment life (Correct answer)
- To document repairs made after equipment failures for regulatory compliance
- To comply with OSHA maintenance recordkeeping requirements
- To train new maintenance technicians on each building system
Correct answer: To perform scheduled maintenance before failure occurs, reducing unplanned downtime and extending equipment life
A PM program schedules regular maintenance activities before failures occur, improving reliability, extending equipment life, reducing emergency repairs, and maintaining regulatory compliance with NFPA and TJC requirements.
In healthcare, PM is not optional — NFPA 99, NFPA 101, and TJC standards mandate specific inspection and testing frequencies for critical systems. An effective PM program is built on a CMMS that tracks asset inventory, PM schedules, work order completion, and maintenance costs. Facilities with robust PM programs have lower emergency repair costs and better regulatory compliance rates.
Question 2: Which type of maintenance is performed after an equipment failure has occurred?
- Corrective (reactive) maintenance (Correct answer)
- Preventive maintenance
- Predictive maintenance
- Condition-based maintenance
Correct answer: Corrective (reactive) maintenance
Corrective maintenance (also called reactive maintenance or run-to-failure) is performed after an equipment failure to restore it to operational condition.
While reactive maintenance is unavoidable for unexpected failures, relying on it exclusively for critical healthcare systems is dangerous and expensive. Unplanned failures of HVAC, electrical, or medical gas systems can directly endanger patients. Reliability-centered maintenance (RCM) principles help determine which assets should have preventive maintenance, predictive monitoring, or can acceptably run to failure based on consequence analysis.
Question 3: In a hospital's CMMS (Computerized Maintenance Management System), what information is typically captured in a work order?
- Asset ID, work description, labor hours, parts used, technician assigned, and completion date (Correct answer)
- Only the technician's name and repair cost
- Patient information related to the maintenance request
- Annual budget projections for the department
Correct answer: Asset ID, work description, labor hours, parts used, technician assigned, and completion date
A CMMS work order captures comprehensive information about each maintenance task: the asset involved, description of work performed, time spent, materials used, responsible technician, priority, status, and completion date.
The CMMS work order history is invaluable for managing assets, proving regulatory compliance, supporting budget decisions, and identifying chronic problem equipment. During TJC surveys, surveyors request equipment maintenance records — the CMMS provides this documentation. Facilities without adequate CMMS documentation struggle to demonstrate compliance with mandatory PM requirements.
Question 4: What does 'mean time between failures' (MTBF) measure for healthcare building equipment?
- The average time a piece of equipment operates between breakdowns, indicating its reliability (Correct answer)
- The time required to repair equipment after it fails
- The time between scheduled preventive maintenance inspections
- The expected useful life of a piece of equipment
Correct answer: The average time a piece of equipment operates between breakdowns, indicating its reliability
MTBF measures equipment reliability by calculating the average time between failures. A higher MTBF indicates more reliable equipment; tracking MTBF over time can reveal deterioration and help predict when replacement is warranted.
MTBF data helps healthcare facility managers make evidence-based maintenance and replacement decisions. When a critical piece of equipment's MTBF begins declining despite normal PM, it signals increasing unreliability and may justify early replacement before a catastrophic failure occurs.
Question 5: In healthcare facilities, which environmental control is critical for maintaining proper pressure relationships in an operating room?
- Positive pressure relative to adjacent areas, preventing outside contaminants from entering (Correct answer)
- Neutral pressure equal to the corridor
- Negative pressure to contain any airborne surgical by-products
- Positive pressure only in the evening when ORs are unoccupied
Correct answer: Positive pressure relative to adjacent areas, preventing outside contaminants from entering
Operating rooms must maintain positive pressure relative to corridors and adjacent spaces, so that clean supply air flows outward, preventing contaminants from the less-clean corridor from entering the sterile field.
FGI Guidelines and ASHRAE 170 specify that ORs maintain at least +0.01 inches of water column positive pressure relative to the corridor. This pressure relationship must be verified during commissioning and monitored continuously. HVAC maintenance that maintains positive pressure is directly linked to surgical site infection prevention.
Question 6: What is the purpose of performing a megohm (insulation resistance) test on electrical motors in a healthcare facility?
- To detect insulation degradation that could lead to motor failure or electrical fault (Correct answer)
- To measure the motor's energy consumption under load
- To verify the motor's speed controller is calibrated correctly
- To test the ground fault protection for the motor circuit
Correct answer: To detect insulation degradation that could lead to motor failure or electrical fault
A megohmmeter applies high DC voltage to measure the resistance of motor winding insulation. Declining insulation resistance indicates moisture intrusion, contamination, or thermal degradation, allowing planned replacement before catastrophic failure.
Regular megohm testing is part of a predictive maintenance program for critical motors (HVAC fans, pumps, air compressors). IEEE 43 provides guidance on test methods and acceptable resistance values. Trending this data over time allows facility teams to identify motors approaching failure and schedule planned replacement.
