01 / Occupational profile
Your 89D occupational profile
Repeated blast overpressure
Assignment-dependent
Controlled detonations, disposal-range demolitions, and close-proximity render-safe procedures expose EOD technicians to repeated blast overpressure over a career, a cumulative pattern distinct from a single blast event and increasingly recognized in military traumatic-brain-injury research as a distinct risk category.
Bomb-suit heat load
Common occupational factor
The bomb-disposal suit is heavy and poorly ventilated, and wearing it during render-safe procedures produces substantial core-temperature elevation and cardiovascular strain, particularly in hot climates.
Heavy equipment handling
Common occupational factor
Manually moving and maneuvering EOD robots, containment vessels, and disposal tools in field conditions is a substantial and recurring physical demand of the job.
Energetic-material and explosive-compound exposure
Common occupational factor
Direct handling of propellants, explosive compounds, and energetic materials during render-safe procedures and training is a chemical exposure specific to this occupation.
High cumulative operational-stress exposure
Assignment-dependent
The combination of repeated close-proximity work with lethal devices, high-stakes decision-making under time pressure, and, for many technicians, direct involvement in casualty-producing incidents represents a documented high cumulative stressor load distinct from general combat-support duty.
02 / Your service
What did you actually do?
Your MOS is the starting point. Your actual assignment, era, equipment, location, and duties determine which parts of the occupational history are relevant. Use the Evidence Builder below to select your actual duties and see records that may corroborate them.
EOD technicians respond to and render safe explosive hazards ranging from legacy unexploded ordnance to improvised explosive devices, often working in close proximity to the device during disruption or disposal operations. Controlled detonations, breaching operations, and disposal-range demolitions expose technicians to repeated blast overpressure over a career, distinct from a single-incident blast injury. Bomb-disposal suits, worn during many render-safe procedures, are heavy and poorly ventilated, producing substantial heat and cardiovascular load during use, sometimes in extreme ambient temperatures. Equipment — robots, containment vessels, tools, and the suit itself — is heavy and must be moved and maneuvered manually in the field. Direct handling of energetic materials, propellants, and explosive compounds during render-safe procedures and training brings chemical exposure not present in most other MOSs.
Duties that may vary by assignment
- Responding to and rendering safe unexploded ordnance and improvised explosive devices
- Conducting controlled detonations and disposal-range demolitions involving repeated blast exposure
- Wearing a heavy, poorly ventilated bomb-disposal suit during render-safe procedures, often in high heat
- Manually moving and maneuvering heavy equipment, robots, and containment vessels in the field
- Direct handling of energetic materials, propellants, and explosive compounds during training and operations
- Working in close proximity to explosive devices during disruption and neutralization procedures
- Sustained high-stress operational tempo with irregular response schedules

Building your occupational history
Records matter because they can connect a job title to an individual's actual work and circumstances.
Repeated blast overpressure
Records that may corroborate it
- · EOD incident and render-safe procedure logs
- · Line-of-duty determinations for specific blast events
- · Unit training records documenting demolition and disposal-range frequency
Limit: A career of blast exposure does not by itself establish a current TBI diagnosis or its residuals; current neurological or neuropsychological findings and a supporting opinion are still required.
Bomb-suit heat load
Records that may corroborate it
- · Render-safe procedure logs documenting suit-wearing duration
- · Heat-illness treatment records, if any occurred
- · Deployment location records establishing climate conditions
Limit: Heat-load exposure alone does not establish a current cardiovascular or heat-related diagnosis; a documented incident or clinical findings and a nexus opinion are still needed.
Heavy equipment handling
Records that may corroborate it
- · Equipment manifests and operational logs
- · Sick-call entries describing back or shoulder strain
- · Physical profiles (DA Form 3349) for musculoskeletal complaints
Limit: Equipment-handling duty alone does not establish a specific joint or spine diagnosis; current findings and evidence of in-service onset are still required.
Energetic-material and explosive-compound exposure
Records that may corroborate it
- · Hazardous-material training records specific to EOD operations
- · Render-safe procedure documentation listing materials handled
- · Treatment records for any acute chemical exposure incident
Limit: Handling these materials alone does not establish a specific systemic or respiratory diagnosis; documented incidents and current clinical findings are still needed.
High cumulative operational-stress exposure
Records that may corroborate it
- · EOD incident logs and after-action reports
- · Awards and badges specific to EOD operational service
- · Behavioral-health encounters during or after service
Limit: EOD assignment alone does not establish a qualifying PTSD stressor; a specific event should be described, and a DSM-5 diagnosis and nexus are still required under 38 CFR § 3.304(f).
04 / Evidence standard
What your MOS can — and cannot — establish
May help document
Work performed, circumstances of service, consistency of an alleged exposure, and the nature or duration of duties where supported by individual records.
Does not automatically establish
A diagnosis, medical causation, severity, percentage, presumption, or entitlement to service connection.
05 / Medical evidence
Conditions that may be relevant to the occupational history
This is not a list of conditions to claim. A veteran's actual diagnosis and individual service record determine relevance; occupational evidence is not medical causation.
Neurologic / TBI +
TBI residuals, headaches, and cognitive symptoms
Why the occupation may matter: Repeated career-long blast overpressure exposure during controlled detonations and render-safe procedures is a recognized cumulative-injury mechanism increasingly studied in EOD populations.
Records and clinical evidence: Incident and procedure logs documenting blast frequency, current neurological or neuropsychological findings, and evaluation under the DC 8045 facets.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Hearing +
Tinnitus and hearing loss
Why the occupation may matter: Repeated demolition and controlled-detonation exposure is a recognized hazardous-noise source.
Records and clinical evidence: Current tinnitus report or audiometry meeting 38 CFR § 3.385, along with demolition and range records.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Cardiovascular +
Hypertension and heat-related cardiovascular strain
Why the occupation may matter: Sustained heat load from bomb-suit use during render-safe procedures places cumulative cardiovascular strain on technicians, particularly in hot climates.
Records and clinical evidence: Current diagnosis, procedure logs documenting suit-wearing duration and climate, and a nexus opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Lumbar/shoulders +
Lumbar strain, rotator cuff pathology
Why the occupation may matter: Manual handling of heavy EOD equipment and robots in field conditions is a substantial mechanical stressor.
Records and clinical evidence: Current diagnosis with examination findings and documentation of equipment-handling duty.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Mental health +
PTSD, depression, and anxiety
Why the occupation may matter: Close-proximity work with lethal devices and, for many technicians, involvement in casualty-producing incidents represent a high cumulative stressor load.
Records and clinical evidence: A DSM-5 diagnosis, a described stressor corroborated where feasible with incident logs or awards, and treatment records.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Respiratory +
Asthma and chronic respiratory conditions
Why the occupation may matter: Inhalation of combustion byproducts and energetic-material particulates during disposal operations is a plausible respiratory stressor.
Records and clinical evidence: Current pulmonary testing, documentation of specific operations and materials handled, and a nexus opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Skin +
Contact dermatitis and skin conditions
Why the occupation may matter: Direct handling of explosive compounds and propellants during render-safe procedures brings recurring skin contact with these materials.
Records and clinical evidence: Current dermatological diagnosis, treatment records, and documentation of the specific materials handled.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
06 / Exposure record
ILER and toxic exposure
For applicable exposure-related claims, VA may review the Individual Longitudinal Exposure Record (ILER) and a toxic exposure risk activity (TERA) memorandum along with deployment and occupational records. An ILER entry does not automatically establish exposure or service connection.
07 / After a decision
Why a 89D claim may still be denied
An exposure finding is not the same as a grant. These are examples from the researched guide, not predictions about a particular case.
VA may accept
A duty or event consistent with the service record
But may deny
A diagnosis, medical relationship, or rating element
Record to examine
Decision findings, service and private treatment records, examination rationale, and medical opinions.
TBI claim denied for lack of a single documented blast event
Because EOD blast exposure is often cumulative rather than a single dramatic incident, examiners focused on finding one discrete injury event can miss the pattern; incident logs documenting repeated procedures over a career are often necessary to establish the cumulative mechanism.
Hearing claim denied despite documented demolition duty
As with other high-noise occupations, VA sometimes requires individualized documentation — range or demolition logs, hearing-conservation enrollment — before accepting the noise exposure as established.
Cardiovascular claim denied for lack of connection to heat-load duty
Hypertension is common and often attributed to general risk factors; without procedure logs documenting suit-wearing duration and climate, an examiner may not consider the occupational heat-load mechanism at all.
PTSD stressor found insufficiently specific despite EOD assignment
EOD-badge or award documentation alone does not identify a specific stressor event; a described incident, with as much corroboration as possible from incident logs or after-action reports, is generally still needed.
Musculoskeletal claims denied for lack of a discrete injury despite years of equipment handling
Cumulative strain from manually maneuvering heavy EOD equipment over a career is sometimes overlooked when an examiner looks only for a single lifting incident.
Oakridge Claims / Appeals Focused
Already have a VA decision?
The important question is what VA accepted, what it rejected, and why. A decision review considers the decision, examinations, and the complete record — including private and VA records that may need development. Oakridge is appeals-focused — core work is post-decision, but initial and new claims are accepted on a case-by-case basis (no fee for pre-decision work).
Fees for eligible post-decision representation are governed by a written agreement. See fee details. No outcome is guaranteed.
89D questions
Does being an 89D automatically qualify me for a TBI claim?
No. It supports the exposure element given the cumulative blast-overpressure pattern of the job, but a current diagnosis, evidence of the exposure's frequency, and a nexus opinion are still required.
I never had one specific blast injury, just years of controlled detonations. Does that matter?
It can still support a claim. Cumulative low-level blast exposure over a career is a recognized concern in EOD-specific research, and incident or render-safe procedure logs documenting the frequency of that exposure are the key evidence to gather.
Can heat exposure from the bomb suit support a cardiovascular claim?
It can support the exposure element if you document how often and under what conditions you wore the suit, but a current cardiovascular diagnosis and a nexus opinion connecting the two are still required.
Does my EOD badge prove I have PTSD?
No. It documents your assignment and qualification, which supports the plausibility of a stressor, but you still need a specific described stressor event, a DSM-5 diagnosis, and a nexus opinion.
What if my incident logs from deployment were not preserved?
Unit after-action reports, awards, buddy statements, and your own detailed account of specific operations can help reconstruct the exposure history where formal logs are unavailable.
Is hearing loss common in this MOS even without an obvious single loud event?
Yes. Repeated demolition and controlled-detonation work is a recognized cumulative-noise exposure, and tinnitus or hearing-loss symptoms are worth documenting and discussing with a provider regardless of whether one specific loud incident stands out.
