Red Seal Sheet Metal Worker Practice Exam

How should sharp edges of cut sheet metal be handled?

1. They should be left as is for safety

2. They should be painted to prevent injuries

3. They should be deburred to prevent injuries

4. They should be discarded immediately

The correct answer is: They should be deburred to prevent injuries

Sharp edges of cut sheet metal can pose significant safety risks, including cuts and lacerations to workers handling the material. Deburring is the process of removing these sharp edges, which not only enhances safety but also ensures a smoother finish on the metal, improving its overall usability and appearance. By deburring the edges, you effectively minimize the risk of injury for anyone who may come into contact with the metal during installation or handling. This practice is a standard safety measure in sheet metal working that prioritizes worker safety and meets industry regulations. While painting sharp edges might seem like a preventive measure, it does not address the underlying risk posed by the sharpness of the edges, and leaving them as is would be unsafe. Discarding the material could be an option for severely damaged pieces, but in cases where the material is still usable, deburring is the most effective approach to enhance safety.
