“Accident” is defined in our Workmen’s Compensation Law to mean “an unexpected or unforeseen event, happening suddenly and violently with or without human fault, and producing at the time injury to the physical structure of the body, by accidental means.” Code, § 7596L “Personal injuries * * * shall not include a disease unless the disease results proximately from the accident.” Id. (j).
The evidence for plaintiff tended to show that while engaged in coal mining he was overcome and for a time rendered unconscious from breathing carbon dioxide or carbon monoxide, or both; that the bad air was due to insufficient ventilation; that the immediate cause of his suffocation was a current of such air passing through an opening he was making into a room where other workmen had been shooting, the gases from the shots not having disappeared.
We have no difficulty in holding that whatever, injury and disability resulted proximately from this event was due to accident within the meaning of the act. Whether his suffocation resulted from breathing such air for several hours, or the inflowing air from the other room for a few minutes, the event “happened suddenly and violently,” as contradistinguished from occupational disease. Taking this evidence as true, the injury was referable to a definite time, place, and circumstances.' 1 Honnold on Workmen’s Com. § 138, p. 539; 1 Schneider’s Work. Com. L., § 135, pp. 303 to 310.
A disease “results proximately from the accident” if the disease is induced by lowered resistance proximately caused by the accident, or if it is aggravated or accelerated by the accident so that the disabling injury results proximately from the accident— would not have developed but for the accident. The benefits of the Workmen’s Compensation- Law (Code, §§ 7543-7597) are not limited to those in perfect health. The test is: Was the accident a proximate contributing cause acting upon the particular individual to produce the disability to work, whether directly or through disease? 1 Schneider’s Work. Com. L., § 138, pp. 312 to 320; 1 Honnold on Workmen’s Com., § 98, pp. 304 to 309.
That the employee was in apparent good health, able to work regularly, that from and after the accident he was unable to work, had symptoms of heart weakness, that disability from abnormal heart condition appeared on examination at the time of the trial, furnishes some evidence of causal connection between the accident and the disability.
Giving full effect to the opinion evidence that persons in good health quickly and fully revive from the effects of carbon dioxide without lasting injury, this must be viewed in the light of all the evidence. It cannot be said with certainty that carbon dioxide alone caused the suffocation.
This court does not review the weight of the evidence on certiorari.
True, the burden of proof in the trial court is on the claimant to prove the conditions upon which his righf to compensation depends. The issue should be' determined fairly upon the legal evidence as in other cases; but the law places that responsibility on the trial judge.
It cannot be declared on this record that there was no evidence of injury from accident within the Workmen’s Compensation Law.
Wirit denied; judgment affirmed.
