In this asbestos personal injury action, the trial court granted defendant Garlock, Inc.’s pre-trial motion to dismiss on the ground that plaintiffs Virgil and Margaret Junge failed to meet their рrima facie burden of proving that Garlock’s asbestos products caused Virgil Junge’s asbestosis. We reverse. 1
*595 Virgil Junge was employed as a boiler and machinery technician and repairman by the United States Navy and the Philadelphia Naval Shipyard over a period of thirty years. During that time, he personally handled Garlock asbestos shеet gaskets, flanges and packing. These materials would harden and become brittle with age, and Junge would have to dig, scratch, scrape, electric wire-brush and sand them in order to remove them from pipes, boilers and other machinery. Junge’s work was conducted in the close confines of the ships’ boiler rooms and machinery spaces, with his face an inch or two from the materials, and the process created dust that Junge breathed. These routines were executed daily, eight hours a day.
The рarties agreed that William Fineman, M.D., plaintiffs pulmonologist expert, would testify in accordance with his report that Junge had asbestos related disease, and that each breath of dusty air that Junge drew substantially contributed to the causation of his disease.
Defendant Garlock concedes that its materials contain asbestos, and that asbestos fibers are released during their use. However, Garlock produced a report by Carl Mangold, an industrial hygienist, who opined that Garlock asbestos products are “encased” or “encapsulated,” and as a result emit a low level of asbestos dust in use. 2 Through the additional testimony of a medical expert, defendant would argue that these low emissions could not have been a substantial factor in causing Junge’s asbestosis.
During pre-trial proceedings, Garlock made an oral motion tо dismiss; the trial judge heard testimony from plaintiff Junge and argument from counsel. Despite Junge’s testimony, which positively identified Garlock’s product and described Junge’s proximate, frequent and regular exposure to dust
*596
emitting from it, Judge Mazer Moss held that because Junge had no industrial hygienist to combat Garlock’s expert testimony, he could not prove that Garlock products were a substantial cause of his condition. The court dismissed the claims against Garlock because Junge “could not identify the asbestos fiber levеls in [the] dust” he breathed.
Junge,
Our case law includes no requirement that a plaintiff in an asbestos case prove through an industrial hygienist, or any other kind of opinion witness,
how many asbеstos fibers are contained in the dust emissions from a particular asbestos containing product.
Instead, in order to make out a prima facie case, it is well estаblished that the plaintiff must present evidence that he inhaled asbestos fibers shed by the specific manufacturer’s product.
Eckenrod v. GAF Corp.,
Junge positively identified the Garlock products with which he worked. He tеstified that he personally worked within an inch of the gaskets and packing on a regular, daily basis; this was not a case of “fiber-drift” throughout a large area. Junge testified that his work produced “all kinds of dust,” such that he would have to “turn around, blow [his] nose and spit this stuff out.” Garlock does not dispute that its gaskets and packing material contained and emittеd asbestos. The evidence would have established that Junge inhaled asbestos *597 fibers shed by Garlock products, and under Eckenrod, supra, a prima facie case of liability was presented. 3
Garlock argues, however, that Junge could never prevail because he did not produce evidence to show that his exposure to its
encapsulated
products was a substantial factor in causing his disease. We disagree. Garlock’s products emit asbestos dust, and Dr. Fineman was prepared to testify that every breath of dust contributed to Junge’s condition. This medical opinion, together with Junge’s own testimony, created a question of fact;

thе facts in this case do not “lead unerringly to but one conclusion.”
Baran, supra
The trial court’s holding that plaintiffs in asbestos actions must present an industrial hygienist who can measure the amоunt of asbestos fibers emitted by a specific asbestos containing product before they may reach the jury is erroneous. 5 No such requirement exists, and we decline tо create it here. 6
*598
What does exist in this case is a prima facie showing of liability, and a credibility contest between the parties’ experts. Credibility questions are for thе jury.
Scott v. Purcell,
Reversed and remanded for further proceedings consistent with this opinion. Jurisdiction relinquished.
Notes
. It is not clear what kind of motion actually was granted below. Garlоck made its oral "Motion to Dismiss” prior to trial, on the ground that plaintiffs had failed to carry their prima facie burden to prove liability. During oral argument on the motion to dismiss, thе Honorable Sandra Mazer Moss stated that the case was "beyond a summary judgment.” Nor was this a true compulsory nonsuit, as the parties had not begun trial. It appears that Judge Mazer Moss was attempting to save the plaintiffs the expense of a trial where it seemed clear that a nonsuit ultimately would be entered. We note that the trial judge, in making her ruling, did consider the evidence proffered by defendant Garlock on the motion to dismiss, and this would be improper on a motion for nonsuit. Pa.R.Civ.P. 230.1.
See Eisenhauer v. Clock Towers Ass.,
. Mangold reported that Garlock’s products emitted airborne asbestos fibers at a rаte below the OSHA standard of 2 per cc. greater than 5 um. in diameter.
Junge v. Garlock,
. Obviously, the facts of this case are distinguishable from situations where the plaintiff has not sufficiently identified the particular product to which he or she was exposed, or proffered evidence that the product identified actually contained asbestos.
. A further factual dispute is presented by the Junges’ argument that Garlock’s industrial hygienist tested only one of the Garlock products used by Junge — "gaskets” but not "packing”. Garlock contends that "packing” and "gaskets” are two terms that refer to the same product.
. Garlock improperly cites several unpublished memoranda in which the plaintiffs' claims were dismissed in thе absence of an industrial hygienist’s testimony regarding the amount of asbestos fibers emitted by a particular product.
