Analysis Of Incidents Involving Injuries Caused By Metal Fragments Due To Improper Installation Of Cable Terminals

Because of improper handling during the connection process of electrical lugs, debris was scattered from the metal end face of terminal lugs, and the flying fragments injured the operator's limbs. This situation not only affects equipment operation but also poses a risk of injury to on-site personnel, and is closely related to the overall quality of electrical installation.

When crimping or tightening cable copper lugs, deviations in cable stripping, terminal positioning, or tool selection can lead to burrs on the terminal pieces, metal fragments, or localized damage. Although these tiny metal fragments are small, they pose a direct impact risk to exposed skin and eyes when flying at high speed.
