Recently, there was a serious injury at another Caterpillar manufacturing facility.
An employee was using a DC powered right angle torque gun to attach a nut, and got her right thumb amputated. This isn't just a recordable injury ; losing a thumb is a life altering event.
The gloved hand was
caught in the rotating swivel socket.
Two tie straps are on the base. One tie strap slipped over the trigger causing the gun to continuously run.
