Combat Engineer: Toxic Exposure and VA Claims

Combat engineers calculate, prime, place, and detonate explosive charges, including TNT blocks, RDX-based C4, detonating cord, shaped charges, and Bangalore torpedoes. The work creates exposure through skin contact while cutting and molding charges and through breathing dust and post-detonation fumes, including fumes from burning excess explosive. ATSDR reports that workers exposed to high concentrations of TNT experienced anemia and abnormal liver function, and long-term exposure has been linked to cataracts. The EPA classifies TNT as a possible human carcinogen based on urinary bladder tumors in animal studies. RDX mainly affects the nervous system and can cause seizures at high exposures; the EPA's 2018 assessment concluded there is suggestive evidence of carcinogenic potential for RDX, based on liver and lung tumors in animal studies.

Open-air burn pits were used to dispose of waste on bases across Iraq, Afghanistan, and the wider region during the Gulf War and post-9/11 eras. Combat engineers who built and expanded base camps, ran route clearance missions, and operated heavy equipment on those installations often lived and worked in the smoke. Under the PACT Act, the VA presumes exposure to burn pits and other airborne hazards for veterans who served on or after August 2, 1990 in locations such as Iraq, Kuwait, and Saudi Arabia, or on or after September 11, 2001 in locations such as Afghanistan, Syria, and Djibouti.

The VA specifically lists demolition, described as knocking down old buildings, along with construction and carpentry, among the military activities associated with asbestos exposure. Combat engineers breached, demolished, and rebuilt structures that could contain asbestos in insulation, flooring, roofing, cement sheet, and pipes. Blasting, cutting, or collapsing those materials releases microscopic fibers that can lodge in the lungs, and asbestos-related disease often appears decades after exposure ends. See the asbestos exposure page for a full breakdown of affected materials and military jobs.

Buildings constructed before 1978 commonly contain lead-based paint, and ATSDR notes that deteriorating paint creates lead-contaminated dust. Demolition, urban breaching, and combat construction in older structures put combat engineers directly into that dust cloud, on installations at home and in damaged buildings overseas. Lead can affect almost every organ and system in the body: it is linked to anemia, kidney damage, and increased blood pressure, and the nervous system is its main target. HHS has determined that lead and lead compounds are reasonably anticipated to be human carcinogens, and the EPA classifies lead as a probable human carcinogen.

Engineer work runs on heavy diesel equipment: bulldozers and earthmovers, dump trucks, mine-resistant route clearance vehicles, and generators. Combat engineers spent long shifts operating that machinery or working on the ground beside it, often in convoys or crowded motor pools where exhaust concentrated. NIOSH designates diesel exhaust a potential occupational carcinogen, based in part on lung tumors in animal studies, and lists the eyes and respiratory system as its target organs, with eye irritation and pulmonary function changes among the documented effects.
