Research sequence

Company name → product → place → time → task → evidence

1. Resolve the entity

Separate the historical company, trust, subsidiary, equipment maker, component maker, distributor and contractor before connecting records.

2. Identify the thing remembered

Record the product name, packaging, equipment, work area or material description exactly as remembered before substituting a modern category.

3. Add the time window

Product lines, formulations, ownership and distribution change. Approximate years can be enough to begin eliminating impossible matches.

4. Test the source

Use the trust’s current governing documents, product/site lists when published, and independent historical records for the particular proposition being made.

Evidence boundary

A company, trust or product-source match is a research lead. It does not by itself establish worksite product presence, a particular person’s exposure, medical causation, liability or trust eligibility. Current official trust documents control trust-specific procedures.
