Asbestos exposure means breathing in or swallowing microscopic mineral fibers that have been released into the air. The fibers are too small to see, and once they reach the lining of the lungs, chest, or abdomen, the body has no good way to clear them. According to the National Cancer Institute, asbestos exposure is the primary cause of mesothelioma, and the disease typically develops 20 to 50 years after exposure (NCI asbestos fact sheet).
Most Pennsylvanians facing an asbestos-related diagnosis today were exposed decades ago, at work or through a family member’s work. This page explains how that exposure happened, which symptoms deserve a doctor’s attention, and how the legal process treats an exposure that dates back to the 1960s or 1970s.
What happens when you breathe in asbestos
The Agency for Toxic Substances and Disease Registry reports that breathing asbestos fibers can cause asbestosis, which is scarring of the lung, as well as lung cancer and mesothelioma, a cancer of the lining of the lungs and abdomen (ATSDR, Asbestos and Your Health). The harm is slow. Fibers lodge in tissue and cause damage over many years, which is why a diagnosis often arrives long after the job ended.
That long delay, called latency, matters legally as well as medically. Pennsylvania law generally starts the clock on a claim when the illness is discovered, not when the exposure happened. More on that below.
How much asbestos exposure is dangerous
Risk rises with the amount of asbestos and the length of contact, but no safe exposure level has been established. The National Cancer Institute notes that everyone breathes trace amounts of asbestos in ambient air, and that the people who become ill are usually those who were exposed on a regular basis, most often in a job where they worked directly with asbestos materials (NCI asbestos fact sheet).
In practice, most Pennsylvania mesothelioma cases involve years of workplace contact: insulation dust in a shipyard compartment, lagging on steel mill pipe, gaskets pulled from refinery flanges. But illness has also followed household-level exposure, which is why the law recognizes those claims too.
Where Pennsylvania workers were exposed
Pennsylvania’s industrial history concentrated asbestos exposure in a handful of settings: the shipyards on the Delaware River, the steel plants of the Lehigh Valley, Johnstown, and Steelton, the Delaware County refineries, the Pennsylvania Railroad shops in Altoona, and the asbestos product factories of Ambler. A working index of these locations is at Pennsylvania asbestos exposure sites.
Exposure tracked trades even more than employers. Insulators, pipefitters, boilermakers, electricians, and laborers carried heavy risk almost everywhere they worked. See jobs with asbestos exposure for a trade-by-trade breakdown.
When the exposure came home on work clothes
The National Cancer Institute reports that family members of asbestos workers faced an increased risk of mesothelioma from fibers carried home on shoes, clothing, skin, and hair (NCI asbestos fact sheet). A spouse who shook out and washed dusty work clothes for years, or a child who hugged a parent still in work gear, could inhale asbestos without ever setting foot in a plant.
Pennsylvania law recognizes these cases. Start with secondary asbestos exposure for the household fact pattern, and asbestos exposure from washing clothes for the laundry cases specifically.
Which symptoms deserve a doctor’s attention
The American Cancer Society lists shortness of breath, chest pain, and a persistent cough among the symptoms of pleural mesothelioma, and abdominal pain or swelling among the symptoms of the peritoneal form (American Cancer Society, Signs and Symptoms of Mesothelioma). These symptoms have many causes, and most of them have nothing to do with asbestos.
The practical step is simple. If you ever worked around asbestos, tell your doctor, even at a routine visit. An exposure history changes what a physician looks for. The medical information on this page is informational only; diagnosis and treatment belong with your care team.
What a Pennsylvania asbestos claim involves
Pennsylvania generally allows two years from discovery of the illness to file a claim, under 42 Pa. C.S. § 5524. Wrongful death and survival actions have their own timing under 42 Pa. C.S. §§ 8301-8302. The details are at the Pennsylvania statute of limitations.
Compensation can come from more than one direction. A lawsuit targets the companies that made or supplied the asbestos products involved. Separately, many of those companies went through bankruptcy and were required to fund trusts for future claimants; the U.S. Government Accountability Office reported roughly $30 billion set aside in asbestos bankruptcy trust funds (GAO-11-819). Trust claims and lawsuits often proceed side by side. See asbestos trust fund claims.
Philadelphia has run a dedicated asbestos docket since 1986 (In re: Asbestos Litigation, No. 1986-00001, Philadelphia Court of Common Pleas). Michael Schafle is counsel in that program.
What this means for your family
You do not need employment records in hand, or the name of a specific product, to find out whether you have a claim. Work histories can be reconstructed from union records, Social Security earnings statements, co-worker testimony, and the site documentation built up over four decades of asbestos litigation. What matters now is the diagnosis, the work history as you remember it, and the filing deadline.
