Two separate reportable accidents occurred recently involving the use of hand held grinders. These both occurred due to grinder kickbacks and both employees were struck in the face by the body of the grinder and sustained serious facial injuries. The first occurred when the individual was completing grinding operations. The electric grinder became entangled with a loose tarpaulin tie rope from a shelter built around the work-station. The second occurred while the employee was cutting along the length of a section of pipe that was held in a vice, the cutting disc snagged in the pipe cut and kicked back striking the worker in the face.
