This is a proceeding brought by the employers and insurance carrier, hereinafter called petitioners, to review an award made on claims filed by claimant, Ray Lawhorn, in which he stated that he sustained an accidental injury arising out of and in the course of his employment with the employers while using a cleaning chemical. An award was made by the State Industrial Commission for temporary total disability and the petitioners have 'brought this proceeding to review the same.
The evidence discloses that claimant was employed in the cleaning establishment of employers at Seminole, Oklahoma, from November, 1949, until he quit work on September 23, 1950. Neither he nor his employers were experienced in the cleaning of furs. He was instructed on just one occasion in the presence of one of his employers by a salesman for the cleaner as to the method of cleaning furs. This chemical was the one used by claimant. The furs accumulated in the establishment beginning in the months of April and May of each year. They were stored until August and then the furs were cleaned separately and apart from the other cleaning. This work was done on Sundays so that it would not interfere with the other cleaning done in the plant. On Sunday, August 6, and Sunday, August 27, 1950, claimant, alone in the plant cleaned a large number of furs. In the process he used carbon tetrachloride as the principal cleaning chemical. The furs were placed in a drum or tumbler for cleaning. This drum was an ordinary cleaning drum and not specially designed *503for cleaning furs. It was not airtight. Claimant testified that in the process of cleaning he was forced to open the tumbler and place his face slightly inside thereof close to the garments in the process of cleaning and drying the same; that on August 6, 1950, he became sick and the next morning reported to his employers who sent him to physicians chosen by them; that the physicians advised him to go home and go to bed; that he was in 'bed for a period of one week. On the 27th day of August, thereafter he again became ill because of contract with the chemical and was again sent to the same physicians and was off work for one day. Finally he quit work and is now temporarily totally disabled and is being hospitalized in Will Rogers Veterans’ Hospital.
Dr. G. W. Winkelman testifying for claimant stated that he first saw claimant in June, 1951, and that claimant has been under his care since June 29, 1951; that according to the history of the case claimant is temporarily totally disabled by reason of the contact with the carbon tetrachloride. On cross-examination Dr. Winkelman was asked if this condition was due to a gradual subjection to said chemical and he replied that he based his opinion on a mass contact on the two dates given by claimant.
It is first argued that the evidence is not sufficient to sustain the finding that the claimant sustained an accidental injury arising out of and in the course of his employment. An accident as contemplated by the Workmen’s Compensation Law, 85 O. S.1951, § 1 et seq., is distinguished from an occupational disease in that it arises by some definite event the date of which can be fixed with certainty, but which cannot be so fixed in case of an occupational disease. Johnson Oil Refining Co. v. Guthrie, 167 Okl. 83, 27 P.2d 814, 90 A.L.R. 616; Tri-State Contractors v. Althouse, 166 Okl. 296, 27 P.2d 1041; Ross v. Ross, 184 Okl. 626, 89 P.2d 338; C. K. Howard & Co. v. McKay, 189 Okl. 453, 117 P.2d 525; Eagle-Picher Mining & Smelting Co. v. Loyd, 192 Okl. 554, 138 P.2d 536; Douglas Aircraft Co. v. Snider, 196 Okl. 433, 165 P.2d 634. In Tri-State Contractors v. Althouse, supra, after discussing a number of cases of this and other courts, it is stated [166 Okl. 296, 27 P.2d 1042]:
“We do not deem it necessary to undertake to add to these discussions. The question now before us in this case seems to be adversely settled to the contention of the petitioners in the case of Quality Milk Products v. Linde, 159 Okl. 256, 15 P.2d 58, and in the more recent case of Johnson Oil Refining Company v. Guthrie, 167 Okl. 83, 27 P. 2d 814 [90 A.L.R. 616]. In the last case an injury was declared to be accidental in character which resulted from inhaling gas fumes and coke dust over a period of time, ultimately resulting on a date that could be ascertained in a disability to a claimant. * * *»
We are of the opinion and hold that the evidence was sufficient to sustain the finding of the State Industrial Commission that there was an accidental injury arising out of and in the course of the employment.
It is next argued that the evidence is insufficient to sustain the finding of the State Industrial Commission that the disability is caused by the accidental injury. Reference is again made to the testimony of Dr. Winkelman above. Dr. Gallaher filed a report which substantiates the conclusion that the disability is the result of the accidental injury although the report does not contain all of the facts supplied by the direct testimony of Dr. Winkel-man.
In Douglas Aircraft Co. v. Snider, supra [196 Okl. 433, 165 P.2d 636], we said:
“ * * * We have held that in a proceeding before the Industrial Com mission where the disability alleged to exist is of such a character as to require skilled and professional men to determine the cause and extent thereof, the question is one of science and must necessarily be proved by the testimony of skilled professional persons, City of Kingfisher v. Jenkins, 168 Okl. 624, 33 P.2d 1094; and that the cause and extent of a disability resulting from an accidental injury are questions of fact and if there is any competent evidence *504reasonably tending to support the finding of the Industrial Commission, an • award based thereon will not be disturbed on review. * * * ”
See, also, Oklahoma Natural Gas Co. v. White, 187 Old. 627, 105 P.2d 225; Superior Oil Co. v. Swimmer, 177 Old.- 396, 60 P.2d 734; Southern Ice & Utilities Co. v. Barra, 178 Old. 291, 62 P.2d 988; Klein Iron & Foundry Co. v. State Industrial Commission, 185 Old. 424, 93 P.2d 751.
There is competent evidence reasonably tending to sustain the finding that the disability is the result of the accidental injury.
Award sustained.
