No. A company does not escape liability for mesothelioma simply by arguing that the exposure from its product was too small to matter. The argument is common, we hear it in nearly every case, but it is a defense to be answered with evidence, not an automatic exit. There is no established safe level of asbestos exposure, and the law in most states asks whether a company’s product was a substantial factor in causing the disease, not whether it was the biggest one.
At Throneberry Law Group, we have spent about two decades answering exactly this defense. Attorney Michael Throneberry built our mesothelioma litigation practice around product identification and detailed exposure histories because he learned early that the “too small to count” argument collapses when the facts are specific. We know which companies raise it, what they rely on, and how to take it apart.
Does Low Exposure Still Carry Risk
Yes. The National Cancer Institute states that while risk generally rises with heavier and longer exposure, asbestos-related disease has followed brief exposures, and the overall evidence suggests there is no safe level. Dose, duration, fiber type, and the source of the fibers all affect risk, but none of them sets a floor below which a company is automatically off the hook.
That medical reality does not relieve you of proof. You still have to connect the defendant’s product or conduct to your illness. Our post on whether a one-time exposure to asbestos can be harmful explains the medicine in more detail. This post is about the legal fight.
What Companies Argue When They Say the Exposure Was Too Small
The defense takes a few predictable forms. A company may say its product released little dust, that you handled it rarely or briefly, or that your other exposures were so much heavier that its contribution could not have mattered.
The variations we see most often are:
- The dose argument: The company claims the fibers released from its product were below any level that could cause disease.
- The frequency argument: It says you encountered the product too rarely or for too short a time.
- The other-exposure argument: It points to your years at a shipyard or refinery and says those exposures, not its gasket or tile, caused the cancer.
- The product identification argument: It denies that you can prove its product was even present.
Each of these is a question of evidence, and each one is why the quality of the exposure history decides the case.
How We Answer the Low-Dose Defense
Michael Throneberry’s approach starts with product identification. We establish, through your memory, coworker testimony, employment records, purchase records, and the companies’ own documents, that a specific product was on the job and that you breathed its dust. Then we show how often and how closely you worked with it.
Building the Exposure History
A person with mesothelioma has usually encountered asbestos from several products and places over many years. We document all of them, because the law does not require that any single company be the only cause. Our library of asbestos companies reflects decades of this work, and the medical and scientific witnesses we work with explain how repeated, cumulative exposures from multiple sources combine to cause disease.
Turning the Defense Around
The companies that argue “too small” often have internal records showing they knew their products released fibers and chose not to warn. Those documents, uncovered in earlier mesothelioma lawsuits, turn the dose argument into evidence of what the company knew and when.
Can a Company Avoid Liability
Not on this argument alone. A relatively small exposure is still relevant when it is part of your overall exposure history, and a company whose product contributed to that history can be held responsible for its share. The strength of the claim depends on the facts, the evidence, and the law of the state where the case is filed, which is why we investigate before any defendant gets the chance to frame the story.
If a bankrupt company raises the defense, the fight moves to its asbestos trust fund, where exposure criteria are written down and the same product identification work carries the claim.
Nationwide Mesothelioma Lawyers at Throneberry Law Group
When a company tells you its product could not have hurt you, that is the start of the argument, not the end of your case. We build the exposure record that answers it, product by product and year by year, and we are prepared to try the case when a defendant will not take the evidence seriously.
