Heat & Frost Insulators Local 207 — Taylor, Michigan (Downriver Detroit)

Jurisdiction

Downriver Detroit — Wayne County south of the city (Taylor, Wyandotte, Trenton, Ecorse, River Rouge, Southgate, Riverview, Lincoln Park, Allen Park) and the Detroit River industrial corridor

Local 207 organizes the Heat & Frost Insulators across the Downriver Detroit industrial corridor — one of the most-extensively-insulated heavy-industrial regions in the United States. The corridor along the Detroit River from River Rouge south to Trenton concentrated steel-making, chemical manufacturing, power generation, and automotive supply work over a roughly 80-year industrial era. Members were dispatched to the major steel mills (Great Lakes Steel, McLouth Steel), the BASF and Pennwalt chemical complexes at Wyandotte, the DTE Energy Trenton Channel and Monroe generating stations, and the Ford Rouge complex insulation work.

Notable workplaces in Local 207 territory

Through the asbestos era (roughly 1920s through early 1980s), Local 207 members were dispatched to facilities throughout the Downriver corridor — many of which are now documented in federal NESHAP filings, state regulatory databases, and public asbestos litigation records. Major workplaces in the Local 207 historical territory included:

Great Lakes Steel Ecorse / Zug Island (later National Steel, later U.S. Steel) · McLouth Steel Trenton · Ford Rouge complex Dearborn · BASF Wyandotte (formerly Wyandotte Chemicals) · Pennwalt Wyandotte (formerly Pennsalt Chemicals) · DTE Energy Trenton Channel generating station · DTE Energy Monroe generating station · Detroit Edison River Rouge generating station · Chrysler Trenton Engine Plant · Mazda Flat Rock Auto Plant · McLouth Steel Gibraltar · Marathon Petroleum Detroit Refinery · the Detroit River shipbuilding and barge-repair facilities · Beaumont and Henry Ford hospitals downriver · Detroit Salt Mine operations.

These are categories of workplace, not an exhaustive list. Local 207 dispatch records held by the Local’s business office contain the specific job-by-job assignments for individual members.

Why this Local matters for asbestos claims

The Downriver industrial corridor — Great Lakes Steel, McLouth Steel, BASF Wyandotte, the DTE Trenton Channel and Monroe plants, the Ford Rouge complex — represents one of the densest single-region clusters of asbestos exposure in U.S. industrial history. The Detroit-area UAW health funds and the regional Insulators Local dispatch records, together, document among the most-extensively-tracked exposure histories of any U.S. industrial workforce.

Products Local 207 insulators handled

Insulators in any jurisdiction worked the same general categories of asbestos-containing products through the asbestos era. The specific manufacturers varied by region, contract, and decade:

  • Pipe covering — Magnesia, calcium silicate, fiberglass-asbestos blends (Owens-Corning Kaylo, Johns-Manville Magnesia, Pittsburgh Corning Unibestos)
  • Block insulation — Calcium silicate or 85% magnesia block (details on AsbestosIndex)
  • Insulating cement — Dry-mixed asbestos cement, hand-applied to joints and irregular fittings — historically the highest-fiber-release product insulators handled
  • Refractory products — High-temperature furnace and boiler linings (refractory brick) — heavily used at the steel mills and the Marathon Detroit refinery
  • Gaskets and packing — Flange gaskets, valve packing
  • Asbestos cloth and millboard — Outer wrapping, fire blankets, jacketing
  • Spray fireproofing — Monokote and competitor products applied to structural steel

See the Asbestos Products page for the full catalog of products documented in insulator-era exposure.

If you or a family member is a Local 207 insulator

You have one of the most-documented exposure histories of any trade in U.S. occupational-health research. The medical literature has tracked your trade specifically since the 1960s. Your union health funds have actuarial data going back decades. The manufacturers that supplied your jobsites have funded over $30 billion in asbestos bankruptcy trust funds — many of which are still paying claims.
