Why Mesothelioma Cases Occur in Milpitas
Milpitas's most significant asbestos site was the Ford Motor Company Milpitas Assembly Plant, which operated on the former site of a World War II shipbuilding facility from 1955 until Ford closed it in 1983. At its peak, the plant employed over 3,000 workers assembling Ford and Mercury vehicles. Assembly workers handled asbestos-containing brake linings, clutch facings, and gaskets daily. The plant's buildings were constructed with asbestos insulation, fireproofing, and floor and ceiling tiles throughout.
Western Electric Company operated a major manufacturing and distribution facility in Milpitas where telephone equipment and components were manufactured for the Bell System. Western Electric facilities nationwide were known asbestos users — equipment insulation, building materials, and electrical components all contained asbestos in these facilities through the 1970s. Milpitas workers who assembled, tested, or maintained Western Electric equipment faced sustained asbestos exposure.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Milpitas facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Milpitas continues to produce new mesothelioma cases decades after asbestos use was restricted.
As Silicon Valley expanded northward, Milpitas became home to semiconductor fabrication facilities including operations linked to the broader Bay Area chip manufacturing ecosystem. Early semiconductor fabs used asbestos-containing materials in cleanroom construction, high-temperature furnace insulation, and building infrastructure. Workers in these facilities from the 1960s through the 1980s encountered asbestos before the hazards were widely recognized.
Milpitas also experienced a postwar construction boom as it transformed from an agricultural community into an industrial suburb. Schools, civic buildings, apartment complexes, and commercial developments built between 1950 and 1980 incorporated asbestos insulation, floor tiles, ceiling tiles, and pipe covering. Tradespeople who built, maintained, and renovated these structures faced ongoing asbestos exposure.
Milpitas's Asbestos Legacy by the Numbers
Ford's Milpitas plant operated for 28 years and employed over 3,000 workers at peak production. Western Electric's Milpitas facility handled Bell System manufacturing for decades. California allows only 2 years from diagnosis to file a mesothelioma claim — one of the shortest deadlines in the nation. Documenting your asbestos exposure history is a critical first step.
