Heat & Frost Insulators Local 45 — Toledo

Jurisdiction

Toledo and Northwest Ohio — Lucas County and surrounding counties, with some jurisdiction extending into southeastern Michigan

Local 45 organizes the Heat & Frost Insulators across the Toledo industrial region — historically a major glass, automotive, and refinery center. Members were dispatched to the Owens-Illinois and Libbey glass works, the major auto-parts manufacturing complexes, the BP/Sun/Sunoco Toledo refineries, the FirstEnergy/Toledo Edison generating stations, and the major Toledo hospitals.

Notable workplaces in Local 45 territory

Through the asbestos era (roughly 1920s through early 1980s), Local 45 members were dispatched to facilities throughout the jurisdiction — many of which are now documented in federal NESHAP filings, state regulatory databases, and public asbestos litigation records. Major workplaces in the Local 45 historical territory included:

Owens-Illinois (O-I) glass plants · Libbey Glass · Jeep/Chrysler Toledo Assembly · BP Toledo refinery · Sun/Sunoco Toledo refinery · FirstEnergy/Toledo Edison Bay Shore generating station · Davis-Besse Nuclear · ProMedica Toledo Hospital · St. Vincent Mercy · University of Toledo Medical Center · DaimlerChrysler Toledo · Pilkington/NSG Group glass.

These are categories of workplace, not an exhaustive list. Local 45 dispatch records held by the Local’s business office contain the specific job-by-job assignments for individual members. For an active or retired member pursuing an asbestos claim, those dispatch records are typically the foundational evidence establishing which jobsites the member was on and when.

Why this Local matters for asbestos claims

Toledo’s glass and refinery industries were among the most heavily insulated workplaces in Ohio. The Owens-Illinois glass plants — themselves a major asbestos products manufacturer through their Owens-Corning Fiberglas subsidiary — drew thousands of Local 45 insulator-hours.

Products Local 45 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)
  • Gaskets and packing — Flange gaskets, valve packing (Garlock, John Crane, Anchor Packing)
  • Asbestos cloth and millboard — Outer wrapping, fire blankets, jacketing
  • Spray fireproofing — W.R. Grace Monokote and competitor products applied to structural steel
