Lone Star Industries cement plant Cape Girardeau

This crosswalk identifies the major equipment systems and building material categories historically associated with facilities of this type and era. Systems are classified by evidence level. Level 4 entries are industry-system associations — standard equipment and material configurations for facilities of this type — and are labeled accordingly. No Level 4 entry constitutes a finding that any specific product was present at this facility.

Product citations: Trust citations identify the qualifying product for trust claim purposes. A trust citation does not establish that the product was present at this specific facility — it identifies the qualifying product and the applicable trust fund.

Legal note: A crosswalk entry does not establish that any individual worker encountered any specific product. Individual exposure depends on work dates, job classification, duties, proximity to disturbance activities, and other worker-specific facts.
