California reports more mesothelioma diagnoses annually than any other state in the nation — an estimated 280 new cases per year. This reflects California's significant industrial and military history: the state was home to some of the largest naval shipyards in the world, major oil refineries, aerospace manufacturers, and extensive construction activity throughout the 20th century. Workers and veterans across Northern and Southern California were exposed to asbestos in these industries for decades.

Asbestos Exposure History in California

California's asbestos exposure history is extensive and geographically diverse. The San Francisco Bay Area was home to Mare Island Naval Shipyard in Vallejo and Hunters Point Naval Shipyard in San Francisco — two of the largest naval facilities on the Pacific Coast, where tens of thousands of workers built and repaired ships using massive quantities of asbestos insulation. In Southern California, the Los Angeles Naval Shipyard at Terminal Island and Long Beach Naval Station served the Pacific Fleet. The Richmond refinery complex, operated by Standard Oil (later Chevron), exposed thousands of refinery workers to asbestos pipe insulation and equipment seals. California's aerospace industry — concentrated in Los Angeles, San Diego, and the Central Valley — used asbestos in aircraft components and facility construction.

Documented Sites with Detailed Records

Hunters Point Naval Shipyard — San Francisco (1930s–1970s)

One of the largest naval shipyards on the West Coast. Thousands of workers were exposed to asbestos insulation on pipes, boilers, and engine rooms during WWII construction and Cold War maintenance.

Los Angeles Naval Shipyard (Terminal Island) — Los Angeles (1940s–1970s)

A major Pacific Fleet repair and construction facility. Shipbuilders, welders, and pipefitters encountered asbestos-containing insulation throughout hulls and machinery spaces.

Standard Oil Richmond Refinery — Richmond (1930s–1980s)

One of the largest oil refineries on the West Coast. Refinery workers, pipe insulators, and maintenance crews faced chronic asbestos exposure from pipe lagging, boiler insulation, and valve packing.

Mare Island Naval Shipyard — Vallejo (1850s–1996)

The oldest naval shipyard on the Pacific Coast. Submarine and ship construction exposed generations of workers and Navy personnel to asbestos in engine rooms, bulkheads, and insulation throughout the facility.

Lockheed Burbank Plant (Skunk Works) — Burbank (1940s–1980s)

Home to legendary aircraft production including the SR-71 and U-2. Aerospace workers used asbestos-containing gaskets, insulation blankets, and fireproofing materials throughout aircraft manufacturing.

California Mesothelioma Laws & Filing Deadlines

Personal Injury Deadline 3 years from diagnosis
Wrongful Death Deadline 2 years from date of death

California has a 3-year statute of limitations for personal injury mesothelioma claims, running from the date of diagnosis. Wrongful death claims must be filed within 2 years of the date of death. California courts have historically been receptive to asbestos claims and have produced significant plaintiff verdicts. The state also allows claims to be filed against multiple defendants simultaneously, which is important given the many manufacturers whose products appeared at California job sites.
