Asbestos Products & Equipment: Start With the Work
A long list of brand names is not always the best way to remember an exposure. Start with the work: what was installed, repaired, removed, opened, cut, cleaned or replaced—and what equipment or building system was involved.
Mechanical and thermal systems
Think about systems that were routinely opened, repaired or insulated.
- Boilers, steam lines and hot-water systems
- Pumps and valves
- Gaskets and packing
- Insulation and refractory materials
Electrical and industrial equipment
The equipment itself can anchor a maintenance history.
- Electrical distribution and control equipment
- Motors, generators and machinery
- Industrial process equipment
- Plant maintenance and shutdown work
Construction and finishing materials
Building work can be reconstructed by task and area.
- Joint compound and wall/ceiling work
- Flooring and adhesives
- Cements, coatings and sealing materials
- Fire-rated and heat-resistant materials
Vehicles and friction work
Repair histories can be organized around the vehicle, machine and component.
- Brakes and clutches
- Fleet and heavy-equipment repair
- Gaskets and engine components
- Grinding, sanding and component cleaning
Product research works better with place, time and task.
A product category should not float by itself. Record the workplace, approximate years, job or trade, actual task, equipment or system, and who worked nearby. Manufacturer or supplier relationships are added only when records or other evidence support them.

Use the Exposure Relationship Map to move between remembered work, equipment and material categories without assuming that a generic historical relationship proves an individual exposure.
