Under the Workmen’s Compensation Act, the North Carolina Industrial Commission is constituted the agency to hear evidence, resolve conflicts therein, make findings of fact, and state its conclusions. If the findings are supported by competent evidence, they are conclusive on the courts.
Osborne v. Ice Co.,
This Court has held that extra exertion by the employee, resulting in injury, may qualify as an injury by accident.
Gabriel v. New
*701
ton,
When one is carrying on his usual work in the usual way and suffers a heart attack, the injury does not arise by accident out of and in the course of employment. In this case, Mr. Jackson was operating a motor grader removing snow from the highway. The evidence and findings are that he was by himself; that the motor grader stopped and a considerable time thereafter he was found slumped over in the cab of the grader. Death had resulted from what proved to be a massive coronary occlusion. He was on call for -extra hours, but had had periods of rest. The extra hours on call were customary when, by weather conditions, there was need for the use of the machine he operated. The operation of the machine was not exacting physically. The hours during which Mr. Jackson was on duty were usual and customary when the conditions required the use of the scraper to open the section of the highway assigned to him. Mr. Jackson had been performing this same service for 18 years except for the time he was recovering from a prior heart attack.
The evidence in this case was sufficient to justify the Commission in findings of fact and concluding therefrom that Mr. Jackson’s death was not caused by accident arising out of and in the course of his employment. The judgment entered in the Superior Court is
Affirmed.
