Mesothelioma Navy Mesothelioma Navy Quality & Compliance 3 — Questions and Answers
Question 1: Navy boiler technicians had elevated mesothelioma risk primarily because asbestos was used extensively in which shipboard system?
- Boiler insulation, pipe lagging, and steam gaskets (Correct answer)
- Navigation and radar equipment
- Communications wiring
- Anchor chain and deck hardware
Correct answer: Boiler insulation, pipe lagging, and steam gaskets
Boiler rooms relied on asbestos for insulation of boilers, pipe lagging, and gaskets to withstand extreme heat, making boiler technicians among the highest-risk Navy occupations.
Question 2: Which type of Navy vessel is historically associated with the HIGHEST asbestos exposure risk due to its enclosed spaces and heavy use of insulated machinery?
- Aircraft carrier
- Destroyer
- Submarine (Correct answer)
- Patrol boat
Correct answer: Submarine
Submarines had the highest asbestos exposure risk because their confined, sealed environments trapped asbestos fibers and virtually every pipe, gasket, and insulated surface contained asbestos.
Question 3: Navy machinists mates working below decks were exposed to asbestos primarily through which maintenance activity?
- Removing and replacing pipe insulation and gaskets during repairs (Correct answer)
- Painting hull exteriors
- Loading ammunition
- Operating sonar equipment
Correct answer: Removing and replacing pipe insulation and gaskets during repairs
Removing and replacing asbestos-containing pipe insulation and gaskets during routine maintenance released large quantities of airborne fibers directly inhaled by machinists mates.
Question 4: Which shipyard is most historically documented for mesothelioma cases among Navy workers due to its scale of asbestos-intensive ship construction and repair?
- Portsmouth Naval Shipyard (Maine)
- Pearl Harbor Naval Shipyard (Hawaii)
- Norfolk Naval Shipyard (Virginia) (Correct answer)
- Puget Sound Naval Shipyard (Washington)
Correct answer: Norfolk Naval Shipyard (Virginia)
Norfolk Naval Shipyard in Virginia is among the most documented for mesothelioma cases due to its massive scale of WWII-era ship construction and decades of asbestos-intensive repair work.
Question 5: Shipfitters and pipefitters in the Navy faced asbestos exposure when cutting or shaping asbestos-containing materials. Which protective measure was largely ABSENT before the 1970s?
- Respiratory protection (respirators) (Correct answer)
- Welding goggles
- Steel-toed boots
- Hard hats
Correct answer: Respiratory protection (respirators)
Respirators capable of filtering asbestos fibers were rarely provided or required for Navy shipfitters before the 1970s, leaving workers unprotected from inhaling friable asbestos dust.
Question 6: Navy electricians were at risk for mesothelioma because electrical wiring insulation and junction boxes on older ships contained which hazardous material?
- Asbestos-reinforced electrical insulation and fireproofing materials (Correct answer)
- Lead paint only
- Mercury switches
- Polychlorinated biphenyls (PCBs) only
Correct answer: Asbestos-reinforced electrical insulation and fireproofing materials
Electrical systems on older Navy ships used asbestos in wiring insulation, junction boxes, and fireproofing materials, exposing electricians during installation and repair work.
Question 7: Quality compliance standards at a VA mesothelioma center require tumor board review. What does a tumor board primarily determine for each patient?
- The optimal individualized treatment plan through multidisciplinary expert consensus (Correct answer)
- The patient's VA disability rating
- Insurance coverage eligibility
- Whether to refer the case to a legal team
Correct answer: The optimal individualized treatment plan through multidisciplinary expert consensus
A tumor board brings together oncologists, surgeons, radiologists, and pathologists to reach a consensus on the best individualized treatment plan for each mesothelioma patient.
