The only d isconnecting means for the chain conveyor were located on the second floor of th e boiler, next door to the work location. Although the chain involved frequently jumped a tooth on its sprocket, no safety procedures had been written for its r ealignment, nor had safety training been provided to employees. ct from an adjacent sawmill to fire its boilers. A machine fed the waste wood pr oducts onto a conveyor running perpendicular to the output of the machine.
