The Quartermaster (QM) rating maintained navigational charts, publications, and instruments; stood helm watch in the pilothouse; assisted in navigation; and maintained the ship’s log. QMs worked in the pilothouse, chart room, and navigation bridge — spaces with asbestos-containing construction materials documented in the publicly filed asbestos litigation record. The QM’s position at the helm and quartermaster desk placed the rating in direct, sustained contact with the asbestos-containing surfaces of the pilothouse throughout every watch stood at sea.

Documented Exposure Sources

Pilothouse — Blueprint Documentation

The pilothouse, as the ship’s command and navigation center, was constructed with asbestos-containing insulation board on interior bulkheads and overhead, asbestos-containing floor tile underfoot at the helm and chart table, and asbestos-backed panels behind instrument installations. The QM’s watch station was surrounded by these materials for every watch period throughout their sea-duty career.

Chart Room Asbestos Exposure

The chart room, adjacent to the pilothouse, housed the QM’s navigational publications, charts, and instruments. Like the pilothouse, chart rooms were insulated with asbestos-containing bulkhead panels and had asbestos-containing floor tile — construction standard for enclosed spaces aboard pre-1980 Navy vessels.

Quartermaster Duties and Asbestos Exposure Pathways

Navigation Bridge — Asbestos Construction

The QM’s exposure was continuous rather than episodic — unlike engineering ratings whose asbestos exposure occurred during specific maintenance tasks, the QM stood every helm watch surrounded by the pilothouse’s asbestos-containing bulkhead lining, overhead insulation, and deck tile for the full duration of their sea service.

Rating History

The Quartermaster rating is one of the Navy’s oldest designations, maintaining its name and navigation mission throughout the relevant period. QMs attended navigation school at naval training centers and shore commands, placing them in shore-based facilities with asbestos-containing construction materials before and between sea-duty assignments.

The Quartermaster rating qualifies for VA service connection under VA asbestos-claim guidance based on documented asbestos exposure in pilothouses and chart rooms aboard Navy vessels.

The QM’s career-long watch standing at the helm produced continuous asbestos exposure across every sea-duty assignment — a cumulative exposure profile consistent with mesothelioma latency periods of 20–50 years following first exposure.

Key documents for a QM claim:

  • DD-214 Block 11 — primary specialty showing QM rate
  • Ship assignments — duty stations documenting helm watch standing and chart room work
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease

Civil claims may run against manufacturers of asbestos-containing insulation board and floor tile used in pilothouse and chart room construction, and against the manufacturers of asbestos-backed instrument panels installed at the QM’s watch station.
