Q: How do I request medical devices that either aren’t on my Modification Table of Organization and Equipment (MTOE) or are above what’s authorized?
If additional equipment is needed that exceeds your unit’s authorization or is not authorized, discuss the requirement with your unit’s G-3 (Operations Section) to determine if an Operational Needs Statement (ONS) should be submitted. The ONS is a process used to temporarily document an urgent need for a nonstandard/un-programmed capability to correct a deficiency or improve a capability required for mission accomplishment. ONS submission is a G-3 function written and processed IAW AR 71-9, Warfighting Capabilities Determination (Chapter 6 and Appendix B).
Q: When and how often does a radiation producing medical device require a radiation protection survey?
Radiation protection surveys (also referred to as safety compliance/rad surveys) ensure X-ray systems operate according to federal regulations and national standards. The principal goal of a radiation protection survey is to keep patient dose As Low As Reasonably Achievable (ALARA) without reducing the quality of patient care. The concept of ALARA is applied in clinical settings to emphasize the importance of limiting ionizing radiation exposure produced by diagnostic X-ray medical devices. Radiation protection surveys are part of an organization’s Quality Assurance (QA) program for diagnostic X-ray systems improving the benefit-to-risk ratio by optimizing radiation dose and image quality. Radiation protection surveys are performed by (or under supervision of) a qualified expert such as an Army-certified Health Physicist. Under extreme circumstances, exceptions cited in TB MED 521 or stipulated through US Army Public Health Command guidance can be made for locations in other countries or on military vessels.
TB MED 521 requires radiation protection surveys to be performed on radiographic and tomographic X-ray systems before initial clinical use and annually thereafter. If surveys are in a joint-commission accredited facility, they must be performed every two years for intra-oral and panoramic dental radiography equipment or every three years for veterinary radiography systems.
Radiation protection surveys are required after repairs or modifications that may affect patient dose or image quality. Only the affected area of the system must be retested; a resurvey of the entire system is not required. Surveys are additionally not required for system relocation or transport provided no damage has been detected and the system has been tested by a qualified Biomedical Equipment Specialist. If system output has changed or a defect is detected, a new radiation protection survey is required.
Diagnostic X-ray systems in long-term storage don’t require annual surveys. A survey is required, however, when the system is removed from storage and placed into clinical use. The need for X-ray systems deployment availability should be carefully considered before placing the system in long-term storage where the annual survey can lapse.
Survey testing parameters (IAW 21 CFR Chapter 1, Subchapter J) include electrical, mechanical, safety, image quality, and radiation dose as well as shielding/protective equipment and establishment of a performance baseline.
- TB MED 521 (2002)
- Federal Guidance Report FGR 14 (2014)
Q: What is a Radiation Protection Program File (RPPF)? When and why do I need one?
An RPPF must be maintained for each radiation producing medical device to include initial acceptance documentation, FDA Form 2579, the latest DD Form 2164 (X-ray Verification/Certification Worksheet); the initial (and most current) radiation survey, maintenance history, maintenance work orders, and applicable disposition forms. RPPFs must be established IAW AR 25-400-2 (The Army Record Information Management System) using file number 750-8i. These files are federally mandated under Title 21 CFR, Subchapter J, required under both TB MED 750-2 and 521, and are subject to Command Maintenance Discipline Program (CMDP) inspection.
Q: What is the approved automated system for tracking medical device maintenance?
IAW HQDA EXORD 138-21, Global Combat Support System-Army (GCSS-A).
Q: What is the difference between Not Mission Capable (NMC) and an administrative (ADMIN) deadline? Which should I use and when?
IAW AR 750-1, NMC is a condition applied to medical devices that cannot perform their health service mission whereas administrative deadline is when equipment is taken out of service by the commander or field-level maintenance officer because they deem it necessary. HQDA EXORD 138-21 states that NMC must be used when medical device scheduled services are not completed. Medical devices should never be administratively deadlined.
Q: What publications should I be familiar with to perform my job as a 68A/670A in the operating force?
There are several key publications a 68A/670A can rely on to be successful. TB MED 750-2 (Appendix J) includes a checklist of essential publications and regulations that can be referred to for improving job performance. Common publications used to gain better familiarization include AR 750-1, TB MED 750-2, and local Standard Operating Procedures (SOPs).
Q: What is a Global Combat Support System-Army (GCSS-A) Equipment Status Report (ESR) and how is it read and validated?
The ESR documents the status of reportable and non-reportable Not Mission Capable (NMC) medical devices. A good job aid for this is ‘JA Equipment Status Report v4’ found in the End User Manual + (EUM+). To locate this job aid, log into GCSS-A and click the EUM+ link. Access the maintenance button found at the bottom of the screen and click Job Aids in the center of the window; follow instructions to search for the ‘JA Equipment Status Report v4’ job aid. This excellent resource walks through every aspect of the ESR providing examples of real-world scenarios.
Q: How do I know if my medical device is unserviceable and what do I do with an unserviceable device?
Only a technically qualified medical maintainer (MOS 68A/670A or Army (1670 Series) Civilian Equipment Specialist) assigned to a maintenance activity can perform a Technical Inspection (TI) for turn in. If a medical device can’t be serviced due to manufacturer discontinuation of repair parts sales or servicing, the medical maintainer will contact the USAMMA, Maintenance Operation Center-Medical (MOC-M) to determine whether repair can be performed by a Medical Maintenance Operations Division (MMOD).
Maintenance is not authorized and the device is deemed uneconomically repairable, when the medical maintainer determines that the estimated cost of repair exceeds the Maintenance Expenditure Limit (MEL) or that the device is no longer manufacturer supported. At this time, the maintainer will assign the device a supply condition code of H indicating that it’s unserviceable (condemned). At the customer’s discretion, a one-time waiver may be requested for device repair IAW AR 750-1. The unit-appointed senior maintenance manager will review, verify, and authenticate condition code assignment by signature endorsement on the maintenance request. This manager will then notify the customer by memorandum and provide a copy of the maintenance historical record and work request. The maintenance request will be closed at this time regardless of the customer’s intent to request a waiver.
The medical device owner is responsible for contacting their Property Book Officer (PBO) for disposition instructions. The PBO will locate disposition instructions entered in the Army Enterprise Portal (AESIP) Lead Materiel Integrator- Decision Support Tool (LMI-DST) by performing the following steps and will provide these instructions to the owner for device turn in:
- Login to the Army Enterprise Portal (AESIP) https://www.aeisip.army.mil/irj/portal dashboard.
- Use Application DST (LMI DST) and select Item Catalog, NIIN/MCN Catalog.
- Search for applicable National Item Identification Number (NIIN) and select NIIN.
- Refer to disposition Instructions in lower window to determine why the device is obsolete, the replacement National Stock Number (NSN), and turn-in instructions.

Q: What is the Army maintenance standard?
The 10-level standard is a medical device with all accessories needed to perform its basic functions. The 20-level standard is a medical device that has an updated medical-maintenance service completion. AR 750-1 refers to the Army 10/20 standard as one maintenance standard defined by the TM 10/20 series or appropriate/applied technical data plans. Army medical devices meet the 10/20 standard when:
- Fully Mission Capable (FMC)
- All faults are identified IAW prescribed intervals using the ‘items to be checked’ column of applicable TM 10/20 series Preventive Maintenance Checks and Services (PMCS) tables.
- Required parts and supplies are available to perform all repairs, services, and related work that correct field-level medical devices or materiel faults for completion in accordance with DA PAMs 738-751 and 750-8.
- Parts and supplies are required to complete corrective actions but are not available in the unit and are on a valid funded requisition in accordance with AR 710-2.
- Corrective actions (not authorized at field level by applicable Technical Manual (TM) or Maintenance Allocation Chart) require evacuation to the next higher level of support (sustainment) and use appropriate turn-in documentation as cited in AR 710-2 and DA PAM 710-2-1 for turn-in to supply.
- Scheduled services are performed IAW the required (technical publication) service interval. Due to competing mission requirements, units are authorized a 10-percent variance when performing scheduled services IAW DA PAM 750-8 for ground equipment and TM 1-1500-328-23 for aviation equipment. Afloat pre-positioning ships are excluded from this variance requirement.
- All routine, urgent, and emergency maintenance work orders are applied to medical devices and reported in the Modification Management Information System (MMIS) IAW AR 750-10.
- All authorized BII and COEI are present and serviceable on a valid supply request.
Q: How do I track maintenance if the Automated Information System (AIS) is down?
Manual forms are used to record maintenance services. TB MED 750-2 calls for the use of DA Form 2404 (Equipment Inspection and Maintenance Worksheet) or DA Form 2407 (Maintenance Request) to manually track scheduled and unscheduled work-item maintenance services IAW DA PAM 750-8, TB 38-750-2, and local procedures. Manual maintenance tracking is performed when there are inadequate automated maintenance procedures. Maintenance activities must retain a copy of all manual maintenance-request forms for a period of one year following the close date.
Q: How do I know if my device has an Authority to Operate (ATO) or if I’m allowed to connect a medical device to the network?
Before connecting a medical device to the network, contact your unit's S6/G6 shops as well as the medical device Materiel Developer (MATDEV) located at the US Army Medical Materiel Development Activity (https://www.usammda.army.mil/index.cfm/about/contact_us
) for applicable guidance.
- Local S6/G6 SOP
- AMLC Website
Q: Where do I get support for Test Measurement, and Diagnostic Equipment (TMDE)?
The local (or closest) TMDE Support Activity (TSA) schedules and manages verification/calibration services for all general and special purpose TMDE (TMDE-GP and TMDE-SP). The Army’s TMDE program is administered by the US Army TMDE Activity (USATA). TMDE-GP is fully supported by the USATA, is authorized at many activities, and used for the diagnosis/repair of medical devices. TMDE-SP is used for specialized applications such as medical device verification and calibration services. Special support, however, may be required to service TMDE-SP through the Original Equipment Manufacturer (OEM), Medical Maintenance Operations Division (MMOD) Tracy, CA., or through US Army Medical Materiel Center-Europe (USAMMC-E). IAW TB 43-180, para 6-l, owning units are responsible for coordinating medical TMDE-SP shipments destined for the MMOD Tracy calibration facility. In addition, the owning unit is responsible for notifying the supporting unit of the new calibration due date upon return of TMDE. All medical maintenance support organizations with general or special purpose TMDE requiring calibration services must register this TMDE with the local (or closest) TSA. IAW AR 750-43, each command, installation, or unit that uses general or special purpose TMDE will designate a TMDE Calibration and Repair Support (C&RS) coordinator in writing. This coordinator serves as a central Point of Contact (POC) for all TMDE C&RS matters. TB 43-180 specifies the responsible TMDE calibration support facility; when calibration cannot be performed by this facility, contact the local (or closest) TSA for assistance. TMDE-GP may be performance-verified and calibrated by the:
- Local (or closest) TSA
- Army Maintenance Support Company (AMSC)
- Area TMDE Support Team (ATST)
- TMDE Support Center (TSC)
To avoid servicing conflicts, keep track of time when TMDE goes in for service. Request status from your local (or closest) TSA or from MMOD Tracy. Contact information for MMOD Tracy can be found in SB 8-75-S6. If your TMDE won’t make it back in time to perform equipment services, attempt to borrow TMDE from local medical maintenance activities (i.e., other Brigade Combat Teams, combat support hospitals, hospital centers, medical logistics companies, or local Medical Treatment Facility (MTF)). As a last resort, request loaner TMDE from MMOD Tracy through your command. If possible, always try to schedule TMDE service support during periods when the medical device it supports is off cycle for scheduled services.
Q: How often should my Test Measurement, and Diagnostic Equipment (TMDE) be verified?
TMDE calibration intervals are initially designated by the Materiel Developer (MATDEV)/Program Manager (PM) when it first enters Army inventory. When TMDE is fielded to the unit, all required maintenance information is provided. If it isn’t, the Biomedical Equipment Specialist (BES) must request this information from the fielding team. IAW AR 750-43, users in receipt of TMDE must coordinate with the supporting TMDE Support Activity (TSA) to enter the device into the TMDE Integrated Materiel Management System (TIMMS). The calibration/verification schedule is included with device information in TIMMS. The TSA notifies the user when TMDE is approaching its services due date; it’s the user’s responsibility to ensure device availability. Following initial calibration/verification (and to prevent established schedule/equipment record conflicts) an item will normally be scheduled and calibrated based on the interval specified at the time of the last calibration. Calibration/verification information can also be found in TB 43-180.
Q: How do I determine if my medical device has been serviced or needs maintenance/service?
IAW TB MED 750-2, determine if your medical device has been serviced by checking the equipment record in Global Combat Support System-Army (GCSS-A) or ask your medical maintenance section. Preventive, Maintenance, Checks and Services (PMCS) is required prior to device use, to determine if planned maintenance is required, use the ZMPRPT Technical Code (T-Code) in GCSS-Army or ask your supporting medical maintenance activity. The medical device operator can also ask their supporting medical maintenance activity which will perform required maintenance or service.
Q: As a medical device operator, do I need to perform 10-level maintenance? How can I request maintenance or service for my device?
10-level maintenance is important. Operators are the first line of support for medical device sustainment and have direct responsibility for its daily care. Operators should refer to manufacturer literature as their primary resource for service guidance. If a Preventive Maintenance Checks and Services 10 (PMCS10) is available, the operator should use it to determine required service tasks and for supporting guidance pertaining to a medical device in a Not Mission Capable (NMC) status. AR 40-61 calls for medical device operators to:
- Perform PMCS before, during, and after operation IAW manufacturer literature or the applicable Technical Manual (TM).
- Change user-replaceable components and accessories.
- Use TMs, manufacturer literature, and local Standard Operating Procedures (SOPs) for operator-maintenance guidance.
- Request appropriate maintenance-organization support for repairs/services beyond the scope of operator maintenance.
To request device maintenance or service, check with your supervisor to see if your organization has a Biomedical Equipment Specialist (BES) and ask if the BES published an external Standard Operating Procedure (SOP). If so, consult the SOP and follow published the instructions. If an SOP is not available, contact the BES for guidance on how to submit a medical device work order and ask for a copy of the SOP at that time. If your organization doesn’t have a BES, ask your supervisor who the medical maintenance support activity is and whether they published an SOP. If your supervisor doesn’t know, your command staff will; continue following your chain of command until maintenance support is found. Regardless of who your medical device support provider is, a work order must be initiated describing the equipment (National Stock Number (NSN), serial number, nomenclature, and problem). Provide the work order and associated medical device to the medical maintenance support activity.

Q: What should I do to maintain or dispose of medical device batteries?
Follow manufacturer recommendations for use, storage, and disposal of batteries to prolong battery life and ensure safe medical device operation. Here are some tips:
Battery use - Batteries operate and charge over wide temperature ranges but there are limits to battery charging and the use of batteries in extreme (high/low) temperature conditions.
Battery storage - Depending chemistry type, rechargeable batteries should be stored in a charged condition. Some batteries need to be recharged every few months during storage while others just need a recharge before use. Remove alkaline batteries from medical devices before placing your device in long-term storage.
Battery Disposal - Do not place used batteries in the trash. Understand and follow installation/unit guidance for battery disposal. If battery disposal policies don’t exist, work with your unit’s safety officer to develop a policy in compliance with applicable local and regulatory guidance. Proper battery disposal will protect the environment from harmful chemicals.

Q: What do the markings on a medical oxygen cylinder mean?
Oxygen cylinders are marked to designate the type of cylinder, maximum fill pressure, hydrostatic test date, inspector, manufacturer, and serial number. Markings are normally stamped into the shoulder of the cylinder. The hydrostatic test date and inspector mark indicate when the cylinder was last tested and who tested the cylinder. Most oxygen cylinders are required to be tested every 5 years. Hydrostatic testing ensures that the cylinder can safety hold its maximum fill pressure. There are two other markings that are sometimes found on these cylinders. The plus (+) sign located after the test date designates that the cylinder can be filled to 10% above the pressure stamped on the cylinder. The five-pointed star in the same location designates that the hydrostatic test date has been extended an additional 5 years. A cylinder with a five-pointed star would need to be tested every 10 years.

Q: What are Prescribed Load Lists (PLLs) and Shop Stock?
PLLs are maintenance repair parts that are demand supported, non-demand supported, or are new repair parts for new end items. These repair parts are kept to support a unit’s daily maintenance program. Demand-supported unit maintenance repair parts are parts that have been ordered six or more times within a control period to qualify for initial stockage. Major Army commands may authorize a 180-day or 360-day control period.
Shop stock represents demand-supported repair parts and consumables stocked within an authorized support-level maintenance activity. They are used to accomplish maintenance requests or to facilitate scheduled supported-unit repairs. Shop stock is similar in purpose to repair parts and is kept by a unit in support of organizational maintenance. Shop-stock parts are for internal use only and are issued from an Authorized Stockage List (ASL) at a Supply Support Activity (SSA).

Q: What is the Fire Triangle and why is it important when dealing with oxygen systems?
The Fire Triangle is used to represent the three elements required to support combustion or fire. It is made up of oxygen, fuel, and an ignition source. If any leg of the triangle can be eliminated or controlled, fire risk can be greatly reduced.
Oxygen pressure and concentration have significant effects on the flammability and ignitability of materials. In general, materials are easier to ignite and burn more readily as oxygen pressure or concentration increase. Ignition risk rises at concentrations as low as 24 percent and pressures as low as 50 pounds per square inch. It is also impossible to eliminate the oxygen leg of the triangle especially when dealing with oxygen systems.
Fuel is any material that can be ignited and burned. Some materials are more difficult to ignite than others. Additionally, some materials when ignited are more resistant to sustained burning than others. Materials also vary in the amount of energy they release when they burn. Materials not normally thought of as fuel in 21 percent oxygen burn readily in high concentrations. Materials such as aluminum, which would normally not burn in ambient air, will burn readily in high concentrations of oxygen. Fuel is another leg of the triangle that is impossible to eliminate.
Commonly recognizable ignition mechanisms include heat, sparks, and friction. Due to the nature of oxygen systems, other less recognizable ignition mechanisms include particle impact, rapid pressurization, flow friction, and resonance. The key to the reduction of oxygen fire risk is the control of ignition mechanisms. This is done through proper selection of materials, system design, cleanliness, safe operating practices, and proper maintenance. Understanding and controlling ignition mechanisms is the key to safe operation and maintenance of oxygen systems.

Q: What are the supply condition codes for medical devices?
IAW TB MED 750-2, 8-8, supply condition codes are used to classify the operational state of medical materiel. These codes specifically identify the degree of serviceability, condition, and readiness for issue/use. Condition codes also identify actions underway to change the status of materiel. Medical maintenance activities are responsible for assigning medical-device supply condition codes as warranted, including:
- A - Serviceable medical devices with more than six months of life expectancy remaining.
- B - Serviceable medical devices with less than a six-month life expectancy remaining or medical devices that have reached/exceeded life expectancy.
- F - Unserviceable, economically reparable medical devices.
- H - Unserviceable, uneconomically reparable medical devices that do not meet the criteria to justify repair (e.g., exceeding the Maintenance Expenditure Limit (MEL)). Devices for which repair parts are no longer available qualify for H code condition code assignment. Check with the USAMMA cannibalization point located at Medical Maintenance Operations Division (MMOD) Hill, UT to determine alternative parts availability.

Q: What does ALARA mean and what are its basic principles?
Ionizing radiation, emitted from radiography equipment, can cause dangerous changes to human tissue including risk of genetic mutations and cancer. These changes are irreversible and cumulative over a lifetime. It is therefore essential that maintainers understand the meaning and practice the principles of ALARA.
As defined in 10 CFR 20, ALARA (as low as is reasonably achievable) means making every reasonable effort to maintain exposures to radiation as far below the dose limits as is practical consistent with the purpose for which the licensed activity is undertaken, taking into account the state of technology, the economics of improvements in relation to state of technology, the economics of improvements in relation to benefits to the public health and safety, and other societal and socioeconomic considerations.
To maintain dose “As Low As Reasonably Achievable”, maintainers should follow these three safety principles:
- Time: Minimize the time of exposure.
- Distance: Double the distance between your body and the radiation source; this reduces the radiation exposure by a factor of four.
- Shielding: Use absorber materials such as Plexiglas® for beta particles and lead for X-rays and gamma rays.
References: Code of Federal Regulation 10 CFR 20.1003, Standards for Protection Against Radiation.

Q: How should the Portable Oxygen Generator System (POGS) feed-air compressor be installed and why is it important?
POGS feed-air compressor installation procedures are found in section 1.7 of the POGS installation manual (P/N P33C-MAN-INST-V1.2). Verify the power switch is in the off position before attaching the 208-volt alternating current three-phase power cable to the compressor. Follow all compressor motor-rotation instructions carefully. Avoid severe damage by ensuring current is properly phased to prevent the compressor motor from running in the reverse direction. Because phasing can differ between generators, repeat documented installation instructions anytime the POGS is relocated or the generator is changed. When energizing the feed-air compressor for the first time, momentarily apply power while simultaneously observing output-air directed from the right-side louvers of the compressor case. Strong air flow exiting the louvers indicate proper phasing. If air flow is not immediately observed, turn power off immediately. For improper current phasing, follow all safety precautions cited in POGS installation manual section 1.7.5, Correcting Reversed Feed-Air Compressor Rotation.

Q: What are Scheduled Parts Replacements (SPRs) and how do I manage them?
SPRs fall into the Mission Essential Repair Parts (MERPs) category. These include non-demand supported, limited quantity, carefully selected (or Original Equipment Manufacturer (OEM) recommended) repair parts. MERPs are annually approved and signed by the unit commander for specific mission-critical medical devices authorizing on-hand use to meet an urgent service requirement. SPRs are performed at specific time or usage intervals and can often be identified in the technical manual 20 series, maintenance allocation chart, or in OEM service literature. SPR requisitioning is administered through your unit medical supply section, in accordance with internal standing operating procedures. While SPRs can be rapidly procured in garrison, always consider parts-item availability and the prospect of delays when procuring these items in a deployed environment. Advanced planning is a key factor in maintaining a properly functioning SPR program.

Q: What purpose do Prescribed Load Lists (PLLs) serve? What is shop stock?
PLLs are demand supported, non-demand supported, or new maintenance repair parts used for new end items. They are retained by units to support their daily maintenance program. To qualify as initial unit stockage, demand-supported maintenance repair parts must be ordered six (or more) times within an authorized control period. Army commands, Army service component commands, and direct reporting units have the ability to authorize 180- or 360-day control periods.
Shop stock is used for demand-supported repair parts and consumables that are stocked within an authorized support-level maintenance activity. This stock facilitates supported-unit maintenance requests or scheduled repairs. Shop stock is comparable to repair parts that are retained at the unit level for organizational maintenance. These parts are issued from a Supply Support Activity’s Authorized Stockage List (ASL) and can only be used for internal use.
