'“‘Injury’ and ‘personal injury’ shall mean only injury by accident arising out of and in the course of the employment and shall not include a disease in any form except where-it results naturally and unavoidably from the accident.” Code, § 114-102. In order to be compensable under the compensation act the disease must arise out of, or result from an accident or injury arising .out of, and in the course of, the employment. If the facts show'a causal connection between the injury and the development of the disease the victim of the disease is entitled to compensation. It has been held that where a disease results from a sudden or-unexpected inhalation of gas or fumes it results from an accident or injury within the meaning of the compensation acts. Although the decisions on the subject are not uniform and can not

be entirely reconciled, generally diseases resulting from unusual and unexpected inhalation of gas fumes or dust result from accident within the meaning of the compensation act, but where the injury is the natural result of the existence of conditions necessarily incidental to the work being performed, as where the resulting diseases are occupational diseases, it is held that they do not result from, accident. 71 C. J. 593, § 344. It has been held that where an automobile mechanic inhaled a large amount of exhaust gas from an automobile in the course of his employment, and thereafter contracted pneumonia from which he died, the cause of his injury was the inhalation of the gas although the pneumonia would have -been the immediate cause of his death.

v.
Berkeley Granite Cor.,

Under the facts of the case now before the court the disease of
*535
the claimant’s lungs resulted from an. unexpected inhalation by him of the gas and fumes caused by the welding carried on by him and his fellow employee in the manhole beneath the street, on the occasion in which the claimant and the other employee were repairing the tank underneath the street, and did not result from a diseased condition arising gradually from the character of the work in which the claimant was engaged, and as the natural result of the existence of conditions necessarily incidental to his employment. Such disease resulted rather from unusual and sudden inhalation of gas and fumes on a single and special occasion wholly unexpected by him, as contradistinguished from inhaling such fumes over a considerable period of time as a natural and expected incident to the employment. Under the authorities first above referred to it is our opinion that the disability of the claimant resulting from the diseased condition of his lungs caused by inhaling the gas or fumes from the electric welding on the occasion when he and his fellow employee were working in the manhole beneath the street, was the result of an accidental injury and was therefore compensable under the wprkmen’s compensation act. The undisputed evidence demanded a finding that the claimant’s disability resulted from an injury by accident, and the award by the hearing commissioner and the board denying compensation was without evidence to support it. The fact that the claimant continued to work that day, after being aware of the fumes and after feeling ill effects therefrom, would not bar him from compensation. Negligence of the employee, no matter how gross, will not bar compensation where the injury is otherwise compensable. See
