Theresa Zytkewick, plaintiff and appellee, following the death of her husband, John Zytkewick, as a result of cyanide poisoning, applied for compensation under the workmen’s com-, pensation act. Ford Motor Company, defendant and appellant, the employer of the decedent, denied liability. The deputy commissioner denied the claim upon the basis that there was no evidence of a personal injury arising out of and in the course of the deceased’s employment. On review before the commission, the decision of the deputy commissioner was reversed and compensation was awarded to the plaintiff for total dependency plus the statutory' *312funeral allowance. Defendant, on leave granted, has appealed.

John Zytkewick had been employed by the defendant for a period of 25 years. Just prior to bis death, be had worked as a machine operator on tbe afternoon shift in tbe gear-case department in tbe gear and axle building at defendant’s Rouge plant in Dearborn, Michigan.

On October 11, 1950, decedent arose at tbe usual time, ate bis breakfast, and then took bis morning walk. On returning home, be listened to tbe radio, ate bis lunch, and then took a nap as was bis custom. He left for work at tbe regular time and, according to bis wife’s testimony, at that time was healthy, smiling and talking- to her in bis usual manner. . He rode to work with 4 other Ford employees who also were employed in tbe gear and axle building but not in the same department in which decedent worked. He left tbe plant that evening at 10:30 p.m., walked to tbe employees’ parking lot, and rode part of tbe way home with several other employees. Tbe testimony indicates that at tbe time be left tbe car decedent did not appear well. Decedent left the car at a point 3/4 of a mile' from bis home from which point be usually walked home. He arrived home at 11 p.m. His wife, who bad retired for tbe night, beard him scraping bis shoes on tbe porch at that time but she did not leave her bedroom and, therefore, did not see him that evening.

Tbe next morning decedent’s clothes were found on tbe floor near bis bed; bis shoes were in tbe bedroom. Decedent normally placed bis shoes in tbe bathroom and bung bis clothes behind tbe door of bis bedroom. One empty beer bottle was found in tbe kitchen. Decedent when first seen by bis wife that morning was lying face down on bis bed dressed in *313his underwear. Plaintiff immediately called a doctor. A subsequent autopsy disclosed the cause of death to be cyanide poisoning. An investigation by the police some 15 days later, although admittedly not a microscopic one, failed to disclose any cans, boxes or traces of cyanide about the Zytkewick home. The doctor who testified at the hearing stated that 2-1/2 grains of cyanide, an amount 1/2 the size of the normal 5-grain aspirin tablet, was sufficient to cause death. This testimony was to the effect that an amount of cyanide sufficient to cause death could be carried under the fingernails, on the hand, or on the shoes of a person. The doctor testified that death usually resulted within 1 to 5 minutes after taking the cyanide but some persons had survived for 4 hours. He also stated that some people died after taking less than 2-1/2 grains and others survived after taking larger doses.

Defendant used sodium cyanide in the gear and axle building but the compound was not used in the department in which decedent was employed. Decedent’s work location was some 420 feet from the heatfreating department where cyanide was used in large quantities in a metal hardening process. Decedent frequently walked through the heat-treating department in making his exit from the plant. Testimony indicates that the cyanide was stored in sealed or closed containers in the area around the drinking fountain located 75 feet from decedent’s work location. One witness testified that, subsequent to decedent’s death, he saw cyanide piled on top of these containers. The cyanide was also used in a copper-plating process about 50 feet from the decedent’s work area. Testimony further indicates that stock boxes which had previously contained cyanide were used in shipping material into decedent’s department and about the building. The union safety officer testified that he had made complaints about the *314handling of cyanide in the building. It is plaintiff’s claim that decedent accidentally contacted the cyanide while at work and that the subsequent ingestion of the cyanide was an accidental result of the original contact.

In awarding compensation the commission stated:

“The employee, the only person who would know what happened, is dead and we are without the benefit of his testimony, but certain facts are beyond dispute. He died from the ingestion of cyanide. There was cyanide present in the building in which he worked and although he did not use it in the performance of his duties, his proximity to it made contact with it possible. Potassium cyanide is not freely available to the general public and only a small quantity taken into the body results in almost instantaneous death. It is therefore a compelling inference that the poison must have entered his mouth after he returned home from work. His failure to complete his normal pre-retirement routine makes this conclusion almost inescapable. The presumptions against suicide and criminal action and the absence of any evidence to rebut these presumptions leaves the only remaining explanation that of accidental ingestion. The logical inquiry is where then did he contact the cyanide and the only reasonable answer is that he must have accidentally come in contact with the substance in the building where he worked and that he carried it home on his person. The precise manner in which it was ingested at home need not be established.”

The absence of evidence to rebut the presumption against suicide or death by criminal action leaves, as stated by the commission, the remaining cause of death as that of accidental ingestion of cyanide. Wishcaless v. Hammond, Standish & Co., 201 Mich 192; Hawkins v. Kronick Cleaning & Laundry Company, 157 Minn 33 (195 NW 766, 36 ALR 394). Defendant contends that there was no evidence that *315the accidental death arose out of and in the course of the decedent’s employment. Defendant further contends that the fact that there existed a possibility that the death arose out of and in the course of the employment is insufficient basis for granting the award of compensation. Defendant asserts that liability in the present case was predicated upon conjecture and speculation and not upon competent evidence. Chaudier v. Stearns & Culver Lumber Company, 206 Mich 433 (5 ALR 1673); Hubbard v. Republic Motor Truck Company, 216 Mich 358; Wiio v. Quincy Mining Company, 217 Mich 476; Allen v. Robert Gage Coal Co., 218 Mich 347; Wiltse v. Borden Farm Products Company, 328 Mich 257.

It is the appellee’s contention that the award was based upon a reasonable and natural inference from the evidence before the commission; that the circumstantial evidence in the case properly justified the commission’s finding that the only logical inference that could be drawn was that decedent’s death was caused by an accidental contact with cyanide during his employment. See Rogers v. Ford Motor Company, 287 Mich 104; Dove v. Alpena Hide & Leather Company, 198 Mich 132; Frankamp v. Fordney Hotel, 222 Mich 525; Woodburn v. Oliver Machinery Company, 257 Mich 109; Dulyea v. Shaw-Walker Company, 292 Mich 570.

“The department of labor and industry may draw reasonable inferences from established facts and circumstances, but may not indulge in the assumption of a possibility based on a possibility and a consequent guess.” Marman v. Detroit Edison Co., 268 Mich 166, 169.

*316Was liability in the present case based npon a reasonable inference from the established facts! Or was the finding of the commission an assumption of a possibility based merely upon a possibility!

Appellant seeks to distinguish the cases cited by appellee by pointing out that each of those cases (cited above) involved injuries on the premises of the employer; therefore in those cases the personal injury was incurred in the course of the employment. The logical and reasonable inference was drawn in the above cases in concluding that the injury was accidental. Appellant apparently asserts that an inference from the established facts is permissible to establish the accidental nature of the injury but not to establish that the injury arose out of and in the course of the employment. We do not understand the proper and permissible scope of an inference to be so limited. A proper inference, the resultant of established facts, is not limited to establishing particular elements of the asserted claim.

In Chaudier v. Stearns & Culver Lumber Company, supra, this Court held:

“Where 2 inferences equally consistent with the facts arise out of established facts, one involving liability on the part of the employer under the act and the other relieving him from liability, the claimant must fail.” (Syllabus.)

And in Wishcaless v. Hammond, Standish & Company, supra (p 201):

“We have often held that, if there was competent testimony upon which the conclusions of the industrial accident board were based, we would not weigh that testimony. Section 5465, CL 1915; Reck v. Whittlesberger, 181 Mich 463 (Ann Cas 1916C, 771, 5 NCCA 917); Rayner v. Sligh Furniture Co., 180 *317Mich 168, LRA 1916A, 22, 4 NCCA 851); Vogeley v. Lumber Co., 196 Mich 516. * * *

“In Papinaw v. Railway Co., 189 Mich 441 (12 NCCA 243), it was said (p 448):

“ ‘This claim is by a dependent of a workman who was accidentally killed, and whose evidence is therefore not available. In Grant v. Railway Co., 1 BWCC17,24, it is said:

“ ‘ “If in snch a case facts are proved, the natural and reasonable inference from which is that the accident happened while the deceased was engaged in his employment, I think it falls upon the employer, if he disputes the claim, to prove that the contrary was the case.” ’

“Applying the principles of law above stated to the facts and circumstances shown in this case, we think the inference may be fairly drawn that deceased met with an accident which arose out of and in the'course of his employment.”

The scope of review in compensation cases is limited to a determination of whether there is competent evidence to support the finding of the commission. As stated in Neumeier v. City of Menominee, 293 Mich 646, 648:

“We are not permitted to inquire into the facts, weigh the testimony and perhaps reach a different conclusion from that reached by the department. Eather, we must confine ourselves to a review of the record to determine whether or not there is any competent testimony to support the finding and award as entered.”

If the inference drawn by the commission from the established facts is merely 1 of 2 equally-consistent inferences from the facts, we must reverse the award of the commission under the rule of the Chaudier Case. If the natural and reasonable inference to be drawn from the facts (and therefore not *318equally consistent with a liability-absolving inference) was that inference drawn by the commission, we must affirm the commission’s finding under the authority of the WisJicaless Case, since there was no evidence introduced by the defendant to prove the contrary. There was evidence for the commission to make its findings, and in such a case we do not interfere with its findings.

“The reasonable inferences which may be drawn from the affirmative facts proven are evidence, and not presumptions.” Butrick v. Snyder, 236 Mich 300; Hoffman v. Stickney, 338 Mich 478.

Testimony in behalf of plaintiff tended to establish the absence of cyanide in decedent’s home. Although the investigation by the police was admittedly made some time after the death of the decedent, no trace of cyanide was found at the decedent’s home. Mrs. Zytkewick did not know what cyanide was. The commission was justified in considering this evidence as to the absence of cyanide in the Zytkewick home.

Appellant asserts that there were numerous opportunities for decedent to contact cyanide on the way home. The testimony in the case indicates that 1/2 hour elapsed during the time decedent ceased working and the time at which he arrived home. During that time decedent walked to the employees’ parking lot, rode some distance in another employee’s automobile and walked a distance of 3/4 of a mile to his home. One of the myriad of possibilities hypothesized by appellant is the possibility that decedent may have orally ingested the cyanide at some bar or restaurant on the way home. We do not feel that the time sequence established by the testimony is without significance as a factor to be considered by the commission in determining that such an inference was not as equally consistent with the facts as the inference drawn. • Nor need the *319inference that the decedent contacted cyanide during his walk home be treated as equally consistent with the facts. Cyanide is not commonly contacted on the public streets or in the community. It is a deadly poison and its sale is specifically regulated by statute. See CL 1948, § 338.424 (Stat Ann § 14.746) and CL 1948, § 750.432 (Stat Ann § 28.687).

Under the facts established by the testimony, we cannot say that the commission was in error in concluding that a compelling inference existed that decedent accidentally contacted cyanide during his employment.

Appellant cites the Chaudier, Hubbard and Wiio Cases, supra, as controlling authority. In the Chaudier Case decedent died from alkaline poisoning attributable to the presence of ashes and lye in. his stomach. In that case the presumption against suicide was rebutted by medical testimony that conscious effort was essential to the ingestion of the quantity of the poisonous substance found in decedent’s stomach. In the Hubbard Case decedent died of septic poisoning that developed from a scratch and resulting infection. Testimony indicated that the decedent could have suffered the scratch while doing many chores about his home as well as at work. In the Wiio Case decedent died of blood poisoning that developed from a scratch. In denying compensation this Court, as in the Hubbard Case, held that the decedent could have suffered the scratch while doing chores at home. In the Hubbard and Wiio Cases there was no showing that the injury was incurred while at work. Appellant claims that since in the present case there is no evidence, aside from the inference, that decedent contacted cyanide while at work the claim must be denied. But it is to be noted that in the Hubbard and Wiio Cases the injuries were of the type commonly sustained outside of the course of employment and not *320significantly associated with the decedent’s place of employment. Nor are the facts of the present case analogous to the Wiltse and Allen Cases, supra. In the Wiltse Case the back injury for which the claimant sought compensation was as apt to be caused by bowling, slipping, getting out of bed, or stepping off a curb as by lifting milk cans while at work. In the Allen Case there was no evidence of marks or bruises indicating an external injury such as a fall or electrocution by contact with a cable; the cause of death could not be determined to be accidental and not due to natural causes; death by reason of heart disease was consistent with the available facts.

There is in the present case testimony negativing the probability that the cyanide was contacted while away from work. Aside from hypotheses of appellant, there is no indication of a source of contact of this deadly poison outside of the work area.

The award is affirmed, with costs to the plaintiff.

(dissenting). I am unable to concur in the opinion of Mr. Chief Justice Butzel. In this case, as in all other compensation cases, claimant must produce affirmative evidence to sustain the burden of proof that decedent suffered an accidental injury arising out of and in the course of his employment. The law applicable to the facts in this case is well stated in Wiltse v. Borden’s Farm Products Company, 328 Mich 257, where we again quoted and approved of the following (p 265):

“‘(1) The burden of proving a right to compensation is on the party asserting that right. Pucilowski v. Packard Motor Car Co., 278 Mich 240; Veek v. Wesley Freight Co., 306 Mich 485. (2) In awarding compensation to a plaintiff, the department may not *321indulge in the assumption of a mere possibility in the nature of a guess as to whether plaintiff is entitled to compensation. Ginsberg v. Burroughs Adding Machine Co., 204 Mich 130, 137; Marman v. Detroit Edison Co., 268 Mich 166. (3) Workmen’s compensation provided by the act is not intended to be either sickness, health, or life insurance or to provide benefits for employees suffering from- ordinary diseases of life.’ (Citing numerous cases.) Riley v. Kohlenberg, 316 Mich 144, 148.

“ ‘ “If an inference favorable to the applicant can only be arrived at by conjecture or speculation the applicant may not recover. So if there are 2 or more inferences equally consistent with the facts, arising out of the established facts, the applicant must fail.” ’ Chaudier v. Stearns & Culver Lumber Co., 206 Mich 433, 442 (5 ALR. 1673), quoting Ginsberg v. Burroughs Adding Machine Co., 204 Mich 130, wherein numerous cases are cited.

“The rules just above stated have been adhered to and made the basis of decision in recent cases of this Court. See Cromie v. Florez, Incorporated, 317 Mich 516; Trumble v. Michigan State Police, 325 Mich 237; Daniel v. Murray Corporation of America, 326 Mich 1.”

In writing for affirmance, Mr. Chief Justice Btjtzel bases his opinion upon the following:

“Under the facts established by the testimony, we cannot say that the commission was in error in concluding that a compelling inference existed that decedent accidentally contacted cyanide during his employment.”

The commission, in making an award, reasoned as follows:

“There was cyanide present in the building in which he worked and although he did not use it in the performance of his duties, his proximity to it made contact with it possible. * * *

*322“The logical inquiry is where then did he contact the cyanide and the only reasonable answer is that he must have accidentally come in contact with the substance in the building where he worked and that he carried it home on his person. The precise manner in which it was ingested at home need not be established.”

It is the purest speculation to say that decedent came in contact with cyanide while at work, as his work did not call for the use or handling of cyanide in any form. Moreover, his work was about 420 feet from the place where cyanide was used. There is no evidence that decedent walked through the heat-treat department on the night in question. There is some conjecture that decedent got cyanide on his shoes and from them to his mouth. Again, this in conjecture of the purest kind. It was also advanced that possibly decedent got cyanide under his fingernails and later in his mouth after he reached home. The record clearly shows that decedent had no opportunity while at work to get cyanide on his clothes or any part of his body. We need not surmise how decedent received or when he ingested the cyanide, as this burden does not fall on defendant. Claimant has the burden of showing that decedent came in contact with cyanide during the course of his employment. There is no basis for an award in the case at bar. The award should be reversed and remanded for entry of an order denying compensation. Defendant should recover costs.
