Why Mesothelioma Cases Occur in Cupertino
Cupertino's asbestos exposure history is anchored by Hewlett-Packard, whose sprawling campus along Stevens Creek Boulevard became one of the largest private employers in Silicon Valley. HP's Cupertino facilities were constructed over decades, with earlier buildings incorporating asbestos insulation, ceiling and floor tiles, pipe lagging, and fireproofing that was standard in commercial construction from the 1950s through the 1970s. Maintenance workers, facilities engineers, and renovation crews who worked on HP's original campus buildings disturbed asbestos during routine repairs and upgrades.
Varian Medical Systems (originally Varian Associates) operated major research, manufacturing, and testing facilities in Cupertino, developing medical linear accelerators, vacuum tubes, and microwave equipment. Varian's high-temperature manufacturing processes and its facility infrastructure used asbestos-containing materials in insulation, gaskets, and building construction throughout the company's early decades. Workers who assembled or tested Varian equipment in the original Cupertino facilities encountered asbestos in both the products and the buildings.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Cupertino facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Cupertino continues to produce new mesothelioma cases decades after asbestos use was restricted.
De Anza College, established in 1967, and the surrounding Cupertino school district facilities were largely built during the era of peak asbestos use. School construction workers who built De Anza and the community's K-12 schools, as well as the maintenance workers who have maintained these buildings over the decades, were exposed to asbestos in floor tiles, ceiling tiles, pipe insulation, and building board. Facilities employees at these institutions have filed mesothelioma claims related to their maintenance work.
Cupertino's transition from an orchard community to a technology suburb generated extensive commercial and residential construction throughout the 1950s, 1960s, and 1970s. Every major building project in that era used asbestos-containing materials as a matter of standard practice. The Vallco Shopping Center area, Stevens Creek Boulevard commercial corridor, and surrounding residential neighborhoods were built with asbestos products that remain in older structures today.
Cupertino's Asbestos Legacy by the Numbers
Hewlett-Packard's Cupertino campus spanned millions of square feet built largely during peak asbestos years. Varian Associates pioneered medical technology in asbestos-era facilities. De Anza College opened in 1967 and its original buildings were built with asbestos materials. 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.
