Arlene Young petitions for review of the order of the Workers’ Compensation Appeal Board (Board), which affirmed the denial of her husband’s pre-mortem claim petition and her fatal claim petition. Young asserts that the Board and the Workers’ Compensation Judge (WCJ) erred as a matter of law in failing to adjudge Zinc Corporation of America (ZCA) liable for benefits, where there exists no dispute that her husband, Charles Young, died from an asbestos-related cancer within 300 weeks of exposure while working for ZCA. We agree and, therefore, reverse.
Charles Young, a bricklayer, retired from ZCA in February of 2001, and shortly after, in June of 2001, was diagnosed with mesothelioma. On July 23, 2001, Young filed a claim petition asserting that he acquired the cancer from his workplace exposure to asbestos. Young died in April of 2002, and approximately one month after his death, his widow, Arlene Young, filed a fatal claim petition. For ten years, from 1991 until February of 2001, Young worked for ZCA as a bricklayer foreman. Prior to employment with ZCA, Young worked as a bricklayer for four different employers. The parties do not dispute that, while working for each employer over his approximately forty-five year career, Young encountered exposure to asbestos and they do not dispute that exposure to asbestos caused the fatal cancer. The parties’ dispute centers on whether Young’s exposure to asbestos at ZCA, which company documents establish occurred as late as 1997, caused or contributed to Mr. Young’s cancer. On the issue of causation, each party introduced conflicting competent expert medical testimony. The experts generally agreed that the type of cancer that afflicted Mr. Young develops after a typical latency period of twenty to forty years. Nevertheless, the two physicians who testified on behalf of Mrs. Young opined that exposure at the ZCA workplace contributed to Mr. Young’s disease. The four physicians who testified on behalf of ZCA agreed that, given the latency period, only exposure prior to employment by ZCA caused Mr. Young’s cancer.
The WCJ deemed ZCA’s experts more persuasive and found that asbestos exposure prior to employment by ZCA in 1991 caused Mr. Young’s disease. Based on this finding, the WCJ concluded that Mrs. Young failed to sustain her burden to prove ZCA liable for benefits. The WCJ specifically rejected Mrs. Young’s argument that, under School District of Philadelphia v. Workmen’s Compensation Appeal Board (Polk), 163 Pa.Cmwlth. 201, 640 A.2d 502 (1994) and Marcucci v. Workmen’s Compensation Appeal Board (B.P. Oil Co.), 98 Pa.Cmwlth. 7, 510 A.2d 1262 (1986), her husband’s death from an asbestos-related cancer after exposure to asbestos at ZCA established as a matter of law her right to prevail on the claim without proof that a particular moment or period of exposure at ZCA actually triggered the cancer. The WCJ denied the claim. Thereafter, Mrs. Young appealed to the Board, reasserting her argument regarding causation and contending that the WCJ erred in denying both the lifetime
The Board agreed with the WCJ that Polk and Marcucci could be distinguished on the ground that, in those cases, claimant suffered from a disease caused by cu
Section 301(c)(2) establishes a right to benefits under the Act for disability or death from occupational disease, as follows:
The term? “injury,” “personal injury,” and “injury arising in the course of his employment,”, as used in this act, shall include, unless the context clearly requires. otherwise, occupational disease as defined in section 108 of this act: Provided, That whenever occupational disease is the basis for compensation, for disability or death under this act, it shall apply only to disability or death resulting from such disease and occurring within three hundred weeks after the last date of employment in an occupation or industry to .which he was exposed to the hazards of such disease: And provided further, That if the employe’s com-pensable disability has occurred within such period, his subsequent death as a result of the disease shall likewise be compensable. The provisions of this paragraph (2) shall apply only with respect to the disability and death of an employe which results in whole or in part from the employe’s exposure to the hazard of occupational disease after June 30,1973 in employment covered by [the Act], The employer liable for compensation provided by section 305.1 or section 108, subsections (k), (l), (m), (o), (p) or (q), shall be the employer in whose employment the employe was last exposed for a period of not less than one year to the hazard of the occupational disease claimed.' In the event the employe did not work in an exposure at least one year for any employer during the three hundred week period prior to disability or death, the employer liable for the compensation shall be that employer giving the longest period of employment in which the employe was exposed to the hazards of the disease claimed.
77 P.S. § 411(2)!
In Marcucci, just as in the present case, the claimant’s husband died of mésothelio-
In Polk, the claimant’s husband died of undifferentiated asbestos-related metastatic lung cancer after working for approximately twenty years in jobs exposing him to asbestos inhalation. Presented with conflicting medical testimony as to whether exposure at the last place of employment or, given a latency period of 10 to 35 years, an earlier exposure caused the cancer, the referee, persuaded by employer’s experts, denied benefits. The referee concluded that, inasmuch as the persuasive evidence established that the critical exposure occurred prior to exposure at the defendant’s workplace, the claimant failed to meet her burden to show causation. On appeal, the Board reversed and remanded. Following the award of benefits on remand, employer appealed to our court, challenging the Board’s application of Marcucci on the ground that there the dispositive issue concerned the requirement that exposure occur after June 30, 1973, while the issue in Polk concerned whether, in view of the latency period, exposure at the last employer caused the fatal cancer. However, the Polk court did not find this distinction relevant and, rather, concluded that, as in Marcucci, the issue concerned the interpretation and application of Section 301(c)(2) where testimony tended to establish a critical exposure period prior to work at the last place of employment. Polk, 640 A.2d at 506. The Polk court concluded that the general premise stated in Marcucci still applied, to wit, “that a specific ‘hit,’ or fixed injury, has no place in the occupational disease process, but is tantamount to requiring proofs which were necessary under the pre-1972 era when an accidental injury was required.” Marcucci, 510 A.2d at 1266.
For specified occupational diseases, such as asbestos-related cancer, Section 301(c) assigns employer liability based not on the ascertainment of a specific morbidity trigger date or period but based generally on the period of latest exposure within the 300-week period pre-dating disease manifestation. Specifically, Section 301(c)(2) directs that the employer liable for compensation provided by Section 108(0 (us-
In the present case, the statutory assignment of liability renders ZCA the only employer upon which liability can fall because ZCA was the only site of workplace exposure, albeit briefly,
The WCJ denied Mr. Young’s lifetime claim based, in part, on his admitted lack of earnings loss.
Finally, Young maintains that the presumption set forth in Section 301(e) applies to the present claims and that the Board erred in concluding that ZCA effectively rebutted the presumption. Section 301(e) provides:
If it be shown that the employe, at or immediately before the date of disability, was employed in any occupation or industry in which the occupational disease is a hazard, it shall be presumed that the employe’s occupational disease arose out of and in the course of his employment, but this presumption shall not be conclusive.
77 P.S. § 413.
This presumption does not go to establishing which exposure, during a lifetime career of exposure, actually triggered disease; rather, the presumption establishes that generally, where workplace exposure occurred, this as opposed to non-workplace exposure caused the disease. However, here, it was not disputed that Young’s cancer was caused by his employment. Rather, ZCA argued only that the cancer was caused by earlier periods of employment with other companies and did not attempt to rebut the Section 301(e) presumption with evidence establishing that some non-workplace exposure caused Young’s mesothelioma. Accordingly, we agree that the presumption was not rebutted, but since a specific morbidity trigger date is not a critical element of proof in an occupational disease case, we find this to be of no moment.
We reverse and remand for the calculation and award of benefits.
ORDER
AND NOW, this 5th day of April, 2006, the order of the Workers’ Compensation Appeal Board in the above captioned matter is hereby REVERSED and this matter is REMANDED for the calculation and award of benefits.
Jurisdiction is relinquished.
. While the Board, in footnote 2 of its opinion, states that the denial of the lifetime claim "is not an issue on appeal," Mrs. Young's appeal to the Board explicitly challenged the WCJ’s conclusion of law number 2, ruling that the lifetime claim must be denied because Young had retired prior to diagnosis and, therefore, sustained no earnings loss.
. The Workers' Compensation Act is the Act of June 2, 1915, P.L. 736, as amended, 77 P.S. §§ 1 — 1041.4, 2501 — 2626. Section 301(e) was added by the Act of October 17, 1972, P.L. 930.
. Section 108 was added by th¿ Act of October 17, 1972, P.L. 930, as amended, 77 P.S. § 27.1 and provides, in pertinent part:
The term "occupational disease,” as used in this act, shall mean only the following diseases.
(Z) Asbestosis and cancer resulting from direct contact with, handling of, or exposure to the dust of asbestos in any occupation involving such contact, handling or exposure.
. The Marcucci court stated that the June 30, 1973 date is "jurisdictional to establish a compensable occupational disease under Sec-tión 108(Z) of the Act, but we do not believe proof of the significance of such jurisdictional exposure is required.” 510 A.2d at 1265.
. Although Young worked for ZCA for ten years, according to company records, his exposure during asbestos removal activities amounted to a total 21 hours. Mr. Young testified that, in addition, he encountered airborne asbestos at other times when the material was stirred up by construction activity nearby.
. Al’s Radiator Serv. v. Workmen's Comp. Appeal Bd. (Jorden’s Radiator Serv.), 157 Pa.Cmwlth. 432, 630 A.2d 485 (1993) (ruling that for those occupational diseases not specified in Section 301(c)(2) as subject to the statutory assignment of liability the "last injurious exposure rule applies" and, stating that, "[hinder the last injurious exposure rule, when an employee becomes disabled or dies from an occupational hazard attributable to successive exposures during employment, the employer liable will be the last employer responsible for exposure to the hazard”).
.ZCA contends that the absence of earnings loss was conceded not only by Mr. Young in his testimony but álso by Mrs. Young in her proposed findings of fact submitted to the WCJ. ZCA attached to its brief, as Exhibit C, a copy of these proposed findings. In response, Mrs. Young requested in a reply brief that we strike Exhibit C because the proposed findings were never made a part of the certified record. It is well-established that our review is limited only to the material contained in the certified record and, therefore, we will not consider Exhibit C and grant the request to strike this exhibit. Moreover, the concession in Exhibit C that Young incurred no earnings loss is irrelevant to our determination that he is nevertheless entitled to the payment of medical expenses.
