Question 1 of 7
1. Question
The MLRO at an insurer is tasked with addressing Preventive Maintenance Schedules for Medical Gas Systems during record-keeping. After reviewing an internal audit finding, the key concern is that the facility’s documentation for the medical air compressor system lacks specific evidence of the quarterly particulate and dew point sensor calibration. The facility manager argues that the system’s self-diagnostic features and annual manufacturer service are sufficient to meet safety standards. According to NFPA 99 and ASSE 6010 standards, what is the primary requirement for maintaining these preventive maintenance records to ensure compliance and patient safety?
Correct
Correct: According to NFPA 99, which governs health care facilities, a maintenance program must be established for medical gas and vacuum systems. This program must be based on the manufacturer’s recommendations. Furthermore, the code specifically requires that records of all inspections, tests, and maintenance activities be maintained, including the date of the activity and the identification of the person who performed the work. This ensures accountability and a verifiable trail of system integrity.
Incorrect: Deferring maintenance based on redundancy is incorrect because redundant systems are designed for fail-safe operation, not as a replacement for scheduled maintenance. Relying solely on daily operational logs or major overhaul records is insufficient because specific components like dew point sensors require periodic calibration to ensure gas quality. Finally, stating that these standards are merely recommendations is incorrect; NFPA 99 and ASSE 6000 series standards are regulatory requirements adopted by authorities having jurisdiction (AHJ) and accreditation bodies.
Takeaway: Compliance with medical gas standards requires a documented maintenance program based on manufacturer guidelines that records every specific test and the individual responsible for it.

Question 2 of 7
2. Question
How should Procedures for certifying the installed medical gas system as compliant with all applicable codes, standards, and project requirements. be implemented in practice? Following the completion of a large-scale medical gas piping installation in a new hospital wing, the project manager must ensure the system is legally and technically certified for patient use according to NFPA 99 and ASSE 6000 standards.
Correct
Correct: According to NFPA 99, the final verification of a medical gas and vacuum system must be performed by a party other than the installer or the manufacturer. An ASSE 6030 Medical Gas Systems Verifier is required to perform a series of tests—including cross-connection, valve integrity, alarm function, and gas purity/concentration—to ensure the system is safe for clinical use and compliant with all codes.
Incorrect: Allowing the installer to perform final certification is a violation of NFPA 99 requirements for independent verification, as it presents a conflict of interest. A standing pressure test is a preliminary test performed by the installer (ASSE 6010) but does not constitute a full system certification or verification. While manufacturers may be involved in equipment startup, they do not satisfy the requirement for an independent third-party verifier for the entire distribution system.
Takeaway: Final medical gas system certification must be conducted by an independent ASSE 6030 verifier to ensure objective compliance with NFPA 99 safety standards.

Question 3 of 7
3. Question
If concerns emerge regarding Identifying and resolving issues that arise during the commissioning process to ensure the system operates correctly., what is the recommended course of action? During the final verification of a newly installed medical air system in a critical care unit, the third-party verifier notes that the particulate filtration system is not meeting the purity standards required by NFPA 99, despite the installer’s initial blow-out procedures.
Correct
Correct: According to NFPA 99 and ASSE 6010 standards, if a system fails to meet purity requirements during commissioning, the installer must identify the source of contamination. The correct procedure involves re-cleaning the lines using a high-volume nitrogen blow-out to ensure all particulates are removed. Since the filter elements may have become loaded or compromised during the initial failure, they must be replaced to ensure the system operates at peak efficiency and meets the required air quality standards before the verifier returns.
Incorrect: Increasing the flow rate at the compressor is incorrect as it may push contaminants deeper into the system or damage sensitive components. Installing point-of-use filters is a temporary measure that does not address the underlying contamination in the distribution piping, which is a violation of system design standards. Proceeding with certification while the system fails particulate tests is a direct violation of NFPA 99 safety requirements, as all parameters must be met before the system is deemed safe for patient use.
Takeaway: Any failure to meet purity standards during commissioning requires a full remediation of the piping and filtration components followed by a complete re-verification to ensure patient safety and code compliance.

Question 4 of 7
4. Question
A whistleblower report received by a payment services provider alleges issues with Quality Control Checklists during business continuity. The allegation claims that during a recent emergency expansion of a healthcare facility’s oxygen delivery system, the ASSE 6010 certified installers failed to maintain rigorous documentation standards. Specifically, the report suggests that the quality control checklists for the brazed copper piping were not updated in real-time, potentially masking the use of unqualified personnel. When auditing the project’s compliance with NFPA 99 and ASSE 6010, which of the following findings would most clearly substantiate a failure in the quality control process?
Correct
Correct: According to ASSE 6010 and NFPA 99 standards, all brazing on medical gas systems must be performed by qualified brazers using a qualified Brazing Procedure Specification (BPS). Quality control checklists are essential for providing traceability and ensuring that only personnel with the proper performance qualifications have worked on the system. A checklist that fails to document the BPS and the identity of the brazer prevents the verification of these critical safety requirements.
Incorrect: Option B describes a violation of an internal administrative policy regarding ink color, which does not constitute a failure of the ASSE 6010 technical standards. Option C is incorrect because an ASSE 6020 (Medical Gas Systems Inspector) is a qualified professional to review such work; the lack of a 6030 verifier at the checklist stage is not a failure, as the verifier typically performs the final system testing. Option D is incorrect because while material compliance (e.g., Type K or L copper) must be verified, NFPA 99 does not mandate the recording of individual roll serial numbers on the brazing quality control checklist.
Takeaway: Quality control checklists for medical gas systems must provide documented evidence that all brazing was performed by qualified individuals using validated procedures to ensure system integrity and patient safety.

Question 5 of 7
5. Question
A new business initiative at a fintech lender requires guidance on Respiratory Therapy Equipment Integration as part of internal audit remediation. The proposal raises questions about the final verification steps required when installing new gas-specific outlets for high-flow respiratory therapy equipment in a clinical setting. During the final inspection of a newly installed medical air piping segment intended for ventilator support, which procedure must the ASSE 6010 installer ensure is completed to prevent cross-connection before the system is cleared for clinical use?
Correct
Correct: According to NFPA 99 and ASSE 6010 standards, a cross-connection test is mandatory after the installation of medical gas piping. This procedure involves pressurizing one gas system (e.g., medical air) while keeping all other systems at atmospheric pressure. The installer must then check every outlet and inlet in the facility to verify that only the pressurized gas is flowing from the correct outlets. This ensures that respiratory therapy equipment, such as ventilators, receives the intended gas and prevents potentially fatal cross-connections.
Incorrect: The standing pressure test is a critical step for identifying leaks and ensuring the mechanical integrity of the piping, but it does not verify that the correct gas is connected to the correct outlet. Verifying the color-coding of equipment hoses is an operational safety check performed by clinical staff, not a system installation verification procedure required by ASSE 6010. While secondary shut-off valves (zone valves) are required for system isolation and maintenance, their installation is a design requirement and does not serve as a verification test for gas specificity or cross-connection prevention.
Takeaway: The cross-connection test is the essential verification procedure to ensure gas specificity and patient safety by confirming that each outlet delivers only the intended medical gas or vacuum service.

6. Question
Following an on-site examination at a credit union, regulators raised concerns about Interpreting Code Requirements for Specific Installation Scenarios in the context of whistleblowing. Their preliminary finding is that the internal audit department failed to detect a code violation in a medical gas system installation at a facility owned by the credit union. A whistleblower report indicates that the installer, seeking to reduce expenses, routed the piping through restricted building zones. The audit team must now determine if the installation meets the safety standards required for healthcare facilities. According to NFPA 99 and ASSE 6010, which of the following installation scenarios is strictly prohibited?
Correct
Correct: NFPA 99 Section 5.1.10.11.1.1 explicitly prohibits medical gas and vacuum piping from being installed in elevator shafts, dumbwaiter shafts, or other hoistways. This is a critical safety requirement to prevent mechanical damage to the life-support gas lines and to maintain the integrity of the hoistway.

Question 7 of 7
7. Question
During your tenure as MLRO at a listed company, a matter arises concerning Scheduled Inspections of Piping and Components during outsourcing. The a transaction monitoring alert suggests that a contractor was paid for a full system verification following a major renovation of the oxygen delivery lines. In reviewing the inspection reports to ensure the installation meets ASSE 6010 and NFPA 99 requirements, which of the following observations regarding the piping and components indicates a failure to meet professional installation standards?
Correct
Correct: According to NFPA 99 and ASSE 6010 standards, all shut-off valves (such as zone valves) must be placed in a location where they are readily accessible and must be clearly and permanently labeled to identify the specific areas or rooms they control. Failure to provide accessibility and accurate labeling is a critical safety violation, as it prevents staff from quickly and correctly isolating gas zones during an emergency or maintenance event.
Incorrect: Using BCuP series brazing filler without flux for copper-to-copper joints is actually the standard and required practice to prevent internal contamination. Spacing supports for 1-inch copper tubing at 8-foot intervals is compliant with the maximum support spacing requirements. The presence of a secondary check valve in station outlets is a standard design feature required to allow for maintenance without shutting down the entire zone.
Takeaway: Proper accessibility and clear, accurate labeling of shut-off valves are mandatory safety requirements for medical gas piping systems to ensure effective emergency isolation.
