Metal alligator shears are extremely dangerous. They require: >Comprehensive operator training. >Strict adherence to lockout/tagout procedures during maintenance. >Never placing hands or any body part in the shear zone. >Ensuring the work area is clear and material is properly positioned before cutting. In summary, the metal alligator shear is the workhorse of the scrap yard, prized for its brute-force simplicity and ability to tackle the toughest, most awkward pieces of metal that need to be reduced in size for recycling.
