Do I need the exact asbestos product name to file a Michigan case?

Not always. Many strong cases are proven through work history, job tasks, and facility records—especially where insulated systems were routinely serviced.

What if I worked at multiple Michigan sites for short periods?

That’s common. Mapping short-term jobs can help by showing repeated exposure across similar industrial systems and maintenance tasks.

What’s the fastest record to start with?

Start with a work history list plus any union dispatch history or employer HR records. Once dates and sites are anchored, it’s easier to pull supporting documents.

Michigan Asbestos Exposure Map Guide

If you’re building a Michigan asbestos claim, one of the fastest ways to turn “I worked there” into real proof is to create a Michigan Asbestos Exposure Map—a simple, written map of your job sites, time periods, and work tasks that points directly to the records that matter.

Most people think an asbestos case starts with remembering a brand name. In real life, many strong cases begin with something more reliable: where you worked, when you were there, and what you did. Once those three pieces are organized, the supporting documents are easier to locate—union dispatch logs, contractor rosters, shutdown schedules, maintenance files, vendor lists, purchase orders, equipment manuals, and jobsite drawings.

What a Michigan Asbestos Exposure Map is

A Michigan Asbestos Exposure Map is not a literal Google map. It’s a structured list that links:

Facility name + city (plant, foundry, refinery, power station, mill, school, shipyard, hospital, etc.)
Date range (years and approximate months if possible)
Your role/trade (pipefitter, electrician, millwright, mechanic, insulator, laborer, maintenance, contractor)
Task-based exposure (tear-outs, rebuilds, gasket changes, packing removal, boiler work, refractory repair, valve/pump work, insulation disturbance, demolition, retrofit work)

This “map” becomes the backbone of your proof.

Why the map matters in Michigan claims

Michigan cases often come down to credibility and documentation. A strong exposure map helps you:

Avoid gaps that let defendants claim your exposure is “speculative.”
Tie your work to specific equipment and systems (steam lines, boilers, turbines, pumps, compressors, heat exchangers).
Identify the right records custodians—the contractor, the facility owner, the maintenance department, or the supplier.
Focus the investigation so you’re not chasing everything at once.

How to build your exposure map in 30 minutes

Start with a simple table or bullet list:

Jobsite / City – Years – Trade – Tasks – Any remembered details

Examples of “details” that help later:

Unit names (Boiler 3, Turbine Hall, Pipe Rack, Powerhouse)
Department names (Maintenance, Utilities, Mill Services)
Contractor names (who you worked for)
Outage seasons (spring/fall shutdowns)
Equipment identifiers (pump model, valve type, compressor line)

You don’t need perfection. You need structure.

What records your map helps uncover

Once your map is drafted, it points to the most useful evidence sources, including:

Union dispatch records / work history reports
Contractor payroll rosters and job assignments
Shutdown schedules / outage planning documents
Maintenance logs / job tickets
Equipment manuals and parts lists
Supplier and vendor records (who supplied insulation, gaskets, packing, refractory, cement)
Blueprints and P&IDs that show where asbestos-containing components were used

The goal is simple: convert “I was there” into “here’s the paper trail that proves what I worked around.”
