5. JP-8 Exposure Scenarios

Exposure to JP-8 occurs to military and civilian avionics, aircraft maintenance, and fuel handling personnel through dermal contact with raw fuel or with clothing/gloves saturated with fuel. Through respiratory exposure to fuel in vapor or aerosol phase, or occasionally through oral exposure to atmospheric aerosol or to fuel-contaminated food or water (Harris et al., 1997, Pleil et al., 2000). Exposure of military personnel to JP-8 can also occur through more atypical uses of the fuel. These uses include fueling of land vehicles and equipment, fueling of heaters, use of JP-8 as a coolant (heat sink) in aircraft, aerosolization of JP-8 for use as a combat obscurant, use of JP-8 to suppress environmental sand or dust, or use of JP-8 as a carrier for herbicide applications (Ritchie et al., 2001a). Exposure of non-military, non-avionics personnel to JP-8 occurs primarily through atmospheric, soil or groundwater contamination with JP-8 or its combustion products, or through off-gassing from the skin and clothing of fuel-exposed personnel (Ritchie et al., 2001a). Major identified sources of atmospheric and groundwater contamination with JP-8 include: 1) unavoidable leakage or accidental spillage of JP-8 from manufacturing facilities, transportation and storage systems (including pipelines); 2) fueling/defueling/maintenance operations, aircraft and vehicle operation (including cold start-up of engines); and 3) occasional atmospheric jettisoning (usually above 6,000 ft.) of JP-8 during emergency aircraft landing (Pfeiffer, 1994).

Carlton and Smith (2000) measured JP-8 and benzene exposures during aircraft fuel tank (foam-filled) entry and repair at twelve USAF bases. Breathing zone samples were collected on the fuel handlers during occupational assignments, while instantaneous samples were taken at various points during the procedures with SUMMA canisters and subsequent analysis by mass spectrometry. The highest 8-hr time-weighted average (TWA) was 1304 mg/m3; the highest short-term (15-min average) exposure was 10,295 mg/m3. The instantaneous sampling results indicated benzene exposures during fuel tank repair up to 49.1 mg/m3. These readings occurred within aircraft fuel tanks, from which foam blocks soaked with JP-8 were inspected and removed. In this worst case scenario, workers entering the tanks are required to wear self-contained breathing apparatus (SCBA) and chemically-resistant gloves and boots, but only cotton jumpsuits, allowing extensive dermal exposure. Personnel working outside the fuel tanks, but assisting in removal of the foam blocks, do not typically wear SCBAs, allowing both extensive dermal and respiratory exposure to JP-8 (Pleil et al., 2000).

    Tips on posting on the forums.

    1. Post a clear title like ‘Need help preparing PTSD claim’ or “VA med center won’t schedule my surgery instead of ‘I have a question.
       
    2. Knowledgeable people who don’t have time to read all posts may skip yours if your need isn’t clear in the title.
      I don’t read all posts every login and will gravitate towards those I have more info on.
       
    3. Use paragraphs instead of one massive, rambling introduction or story.
       
      Again – You want to make it easy for others to help. If your question is buried in a monster paragraph, there are fewer who will investigate to dig it out.
     
    Leading too:

    exclamation-point.pngPost straightforward questions and then post background information.
     
    Examples:
     
    • Question A. I was previously denied for apnea – Should I refile a claim?
      • Adding Background information in your post will help members understand what information you are looking for so they can assist you in finding it.
    Rephrase the question: I was diagnosed with apnea in service and received a CPAP machine, but the claim was denied in 2008. Should I refile?
     
    • Question B. I may have PTSD- how can I be sure?
      • See how the details below give us a better understanding of what you’re claiming.
    Rephrase the question: I was involved in a traumatic incident on base in 1974 and have had nightmares ever since, but I did not go to mental health while enlisted. How can I get help?
     
    This gives members a starting point to ask clarifying questions like “Can you post the Reasons for Denial of your claim?”
     
    Note:
     
    • Your first posts on the board may be delayed before they appear as they are reviewed. This process does not take long.
    • Your first posts on the board may be delayed before they appear as they are reviewed. The review requirement will usually be removed by the 6th post. However, we reserve the right to keep anyone on moderator preview.
    • This process allows us to remove spam and other junk posts before hitting the board. We want to keep the focus on VA Claims, and this helps us do that.

    You’ve just been rated 100% disabled by the Veterans Affairs. After the excitement of finally having the rating you deserve wears off, you start asking questions. One of the first questions that you might ask is this: It’s a legitimate question – rare is the Veteran that finds themselves sitting on the couch eating bon-bons … Continue reading
