Opinion by
Claimant-appellee was employed by Sunray Electric, Inc., from August 19, 1946 to August 22, 1946, and from September 23, 1946 to May 26, 1947. During that period she was exposed to beryllium poisoning, the date of the last exposure being May 26, 1947. After employment elsewhere, she became totally disabled from undiagnosed causes on October 8, 1949. Her disability was finally determined on March 10,1951 to have resulted from beryllium poisoning. The referee and the Board awarded compensation under the Occupational Disease Act, and the court below affirmed. The employer, its insurance carrier, State Workmen’s Insurance Fund, and the Commonwealth of Pennsylvania appealed.
Neither the original occupational disease legislation of July 2, 1937, P. L. 2714, nor The Pennsylvania Occupational Disease Act of June 21, 1939, P. L. 566, 77 P.S. §1201 et seq., or the 1945 amendments to the latter Act, included beryllium poisoning among the compensable occupational diseases. That species of disease was first introduced into the legislation by the Act of May 14, 1949, P. L. 1379, §1, effective July 1, 1949, 77 P.S. §1208, which amended §108 of the Act of 1939. Hence, during the entire period of her employment by Sunray and on the day of her last employment and exposure, beryllium poisoning was not covered or recognized by the law as a compensable occupational disease. As a result, she is not entitled to compensation.
When an employer and employe accept the occupational disease legislation, their relation, like that created by the workmen’s compensation statutes, becomes contractual and their rights are to be determined under the applicable provisions of the existing law, which become part of the terms of employment.
