Doringer Cold Saw Accident

Doringer Cold Saw Accident

MASE Product Failure Injury Report

Product involved: Doringer Cold Cutting Chop Saw

What happened:  Worker’s hand caught in saw when he attempted to change the miter angle of the saw with the saw running.  This was done because the cooling fluid would take several minutes to begin flowing upon startup, so the saw was left running all day, and shut off at the circuit breaker at the end of the day. 

Injuries: Severe laceration

Recommendations:  Adjust guard for optimal protection with each particular stock being used, use a blade guard that completely surrounds blade when in the upright position, ensure proper operating procedures for miter adjustment – ensuring that power to the saw is off during adjustment or maintenance.

OSHA/Standard violations?: Not cited
