A workman or his dependents shall not be entitled to compensation hereunder if it is proved that the disablement to the workman results from his deliberate intention to cause such disability, or from his willful failure to use a guard or protection against disablement required pursuant to any statute and provided for him, or a reasonable and proper guard and protection voluntarily furnished him by said employer, or solely from his intoxication.
