Why Mesothelioma Cases Occur in Santa Clara
Santa Clara sits at the heart of Silicon Valley, and its asbestos legacy reflects both its industrial past and its semiconductor present. Intel Corporation established its headquarters and early fabrication facilities in Santa Clara in 1968. These early chip fabs used asbestos-containing materials in cleanroom construction, thermal insulation, ceiling tiles, and building infrastructure. Workers manufacturing microprocessors were exposed to asbestos embedded in the very facilities designed to be ultra-clean.
National Semiconductor (now part of Texas Instruments) operated major fabrication facilities in Santa Clara where asbestos was present in building materials, cleanroom construction, and high-temperature equipment insulation. Westinghouse Electric also maintained manufacturing operations in Santa Clara where transformers and electrical equipment were built using asbestos-containing insulation and gaskets.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Santa Clara facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Santa Clara continues to produce new mesothelioma cases decades after asbestos use was restricted.
The Santa Clara Unified School District has documented asbestos in numerous school buildings constructed between the 1940s and 1970s. Teachers, custodians, maintenance workers, and even students were potentially exposed to asbestos in floor tiles, ceiling materials, pipe insulation, and heating system components in aging school buildings.
Santa Clara's Convention Center, Great America theme park infrastructure, and commercial buildings along El Camino Real all incorporated asbestos-containing materials during their original construction. The city's dense mix of older industrial and commercial buildings means asbestos exposure risks persist during renovation and demolition projects.
Santa Clara's Asbestos Legacy by the Numbers
Intel has been headquartered in Santa Clara since 1968. National Semiconductor operated in Santa Clara for over 40 years. The Santa Clara Unified School District serves over 15,000 students in buildings that required asbestos abatement. California allows only 2 years from diagnosis to file a mesothelioma claim. Documenting your asbestos exposure history is a critical first step.
