Gronenthal, on July 7, 19 6 1, from an order of the supervisor of Industrial insurance dated June 7, 1961, denying the petitioner's claim for a widow's pension on the ground that the decedent's death was due to 1 H /3i^62 * alveolar cell carcinoma, a condition which was alleged to "be un 1 related to his occupation. Reversed and remanded, 2 DECISION 3 The deceased workman, John B. Gronenthal, died on January 12, 4 19 6 1. The issue presented by this appeal is whether the deceased 5 workman developed an occupational disease as a proximate result 6 of his exposure to various commercial insolation materials in 7 the course of his employment in this state from 1942 to i960 as 8 an insulation installer for one or more of the various employers 9 for whom he worked during that period, Simpson Logging Company 10 v. Department of Labor and industries, 32 Wn. (2d) 472 and Favor 11 v. Department of Labor and industries, 53 Wn. (2d) 698; and if 12 so, whether that disease was a materially contributing factor to 13 his death, Towne v. Department o'f Labor and Industries, 51 Wn (2d) 14 644; in the sense that death would not have occurred when it did 15 without such disease, Petersen v.^Department of Labor and indus 16 tries, 40 Wn. (2d) 635, and that he otherwise would have lived , ^ 1 17 for an indefinite and unpredictable time. Mork, v. Department of . 18 Labor' and Industries, 48 Wn. (2d) 74. 1 19 This issue must be decided by the board "upon the evidence1 20 rather than upon the information or experience of /i t s members." ' j 21 Kaiser Aluminum and Chemical Corporation v. Department of Labor 22 and industries, 45 Wn. (2d) 745. 23 It.is clear from the record that from 1942 to I960, Mr. 24 Gronenthal, while working, was exposed to a variety of commercial 25 mineral insulating materials. Spectrographic analysis of these 26 materials establishes that the major constituent of most of them 27 was "silica or a silicate compound." It is uncontroverted on the 28 record that he developed a condition called asbestosis, otherwise 29 described as "interstitial fibroses, diffuse, as a result of having 30 breathed into the lungs these insulating materials which contain 31 silicates and/or silica, large amounts of it, which can be asbestos; and other commercial products." An autopsy report, introduced into the record as an exhibit, establishes (a) that Mr. Gronenthal died as a result of having developed a condition called cor - 2- " pulmonale, which is described as "an enlargement of the right sid'3 of the heart due to resistance of the blood flow through the lungs," and (b) that microscopic examination of the decedent's lung tissue revealed "diffuse bilateral alveolar carcinoma of the lungs (pulmonary adenomatosis)." The real problem presented by this appeal, therefore, is to determine what caused the cor pulmonale condition to develop in the deceased workman's heart. After a careful review of the record before us, we are persuaded that more likely than not, the "asbestos" particles in Mr. Gronenthal's lung tissue were carcinogenic agents which materially contributed to the develop ment of the pulmonary adenomatosis, and that his combined pul monary condition thus created caused the cor pulmonale resulting in his death on January 12, 19 6 1. FINDINGS 1. On January 25, 1961, the department of labor and industries received a claim for a widow's pension from Lilly Nancy Gronenthal, surviving spouse of John B. Gronenthal. On June 7, 19^1, the supervisor of industrial insurance issued an order rejecting the widow's claim for bene fits under the workmen's compensation act. On , - July 7, 1961, the petitioner filed notice of appeal with this board, and on August 3, 19^1, her appeal was granted. 2. From June, 1942, to July, i960, except for the period from September, 1946, to September, 1948, the decedent was regularly employed as an insula-r tion mechanic for se-veral firms engaged in extrahazardous employment in the state of Wash ington. During his employment as an insulation . mechanic the decedent worked with various types "t. of industrial insulating materials, predominantly asbestos products and products made of glass and . extruded glass, which fundamentally are silicas and/or silicates. These products are manufact ured in various shapes and forms, including solid and flexible forms, and their installa tion requires that they be cut, shaped, pounded, . drilled, and worked on with a variety of tools. During the process of installing or applying the insulating materials, dust -composed of'-particles of Insulating materials is present in greater or lesser quantities. The' extent to which the decedent's lungs were exposed to such dust was dependent upon several factors, including the type and form of material, the size and weight of the particles of dust, the extent of - 3 - * 1 ventilation, the temperature, the degree of physical exertion expended by the workman, 2 and the position of the materials being in stalled with relation to the workman. 3 3. As a result of his exposure to dust occasioned 4 by the use of these various industrial insula** ting materials, Mr. Gronenthal developed a 5 pulmonary condition called "asbestosis," other wise described as diffuse interstitial fibrosis. 6 The "asbestos," particles (silicas and/or silicates) in the decedent's lung tissue acted 7 as carcinogenic agents which materially con tributed to the development of alveolar cell' 8 carcinoma of the lungs (pulmonary adenomatosis), and the combined pulmonary disease resulting 9 therefrom caused a condition described as cor pulmonale as a result of which Mr. Gronenthal 10 died on January 12, 19 6 1. ' 11 CONCLUSIONS 12 Based on the foregoing findings of fact, the board concludes; 13 1. This board has jurisdiction of the parties and subject matter of this appeal. 14 2. The order of the supervisor of the super 15 visor of industrial insurance issued herein on June 7, 1961, should be reversed and this 16 claim remanded to the department with in structions to allow the petitioner's claim for 17 widow's benefits under the workmen's compensa tion act and to take such further action as may be 18 authorized or required by law. ' 19 ORDER 20 Now, therefore, it is hereby ORDERED that the order of the 21 supervisor of industrial insurance issued herein on June 7, 19&1, 22 be, and the same is hereby, reversed and this claim remanded to 23 the department with instructions to allow the petitioner's claim 24 for widow's benefits under the workmen's compensation act and to 25 take such further action as may be authorized or required by law. 26 Dated this 30th d a y ^ f November, 1962. 27 28 29 30 31 HAROLD J.
