Both types of safety shoes provide protection for the toes against impact or compression hazards in the workplace. **

The green discoloration of metal jewelry is typically caused by a chemical reaction between the metal and the acids present in the wearer's skin or in the environment. This reaction can result in the formation of copper salts, which appear green in color. The most common metals to cause this reaction are copper and brass, which contain a higher percentage of copper. To prevent this discoloration, it is important to keep metal jewelry clean and dry, and to avoid exposing it to harsh chemicals or acidic substances. **

It is important to check the specifications of safety shoes to ensure they are suitable for environments with metal detectors. **
