Records show what a plant was. They don't show what the work was like. If you
were sent there — insulation, pipe, boilers, sheet metal, electrical, laborer — tell us what you
remember: which units or buildings, what you handled, what came down during an outage. Every account
helps another worker or a family understand where exposure happened, and where to look next.
About these accounts: they are personal recollections shared by
workers and their families — individual memory, not records, and not independently verified.

These accounts sit alongside that record — they add to it, they don't change it.

Is there a deadline to file an asbestos claim in California?
California law gives 5 years from the date of medical diagnosis to file a personal-injury asbestos lawsuit. Wrongful-death claims must be filed within 3 years from the date of death. The two deadlines run on separate tracks. The personal-injury clock starts at diagnosis, not at exposure — mesothelioma latency is typically 20 to 50 years.
Who else besides Litton Industries — California Plant Asbestos Exposure workers may have been exposed?
Yes. Spouses who laundered work clothing carrying asbestos fibers and children of workers who returned home covered in dust are recognized in California asbestos litigation as eligible for secondary (household) exposure claims when they have been diagnosed with an asbestos-related disease. Wrongful-death claims may be filed by surviving family members.
Can workers file both a civil suit and trust-fund claims?
Yes — more than 60 asbestos bankruptcy trusts hold combined funds set aside specifically for victims of asbestos-related disease. Trust-fund claims and civil lawsuits run on separate tracks; both can be pursued in parallel. Each trust has its own filing requirements, exposure criteria, and processing timeline.
