The assertion that fiber optic shards of glass are extremely sharp and can easily penetrate skin is accurate. Fiber optic cables are made from very thin strands of glass that can break during installation, handling, or due to environmental factors. When these glass fibers break, they can create tiny shards that are indeed sharp and pose a risk of penetrating skin, leading to injuries.

The potential danger is heightened by the fact that these shards can be difficult to see, making it hard for individuals to notice them and thus increasing the likelihood of accidental cuts or punctures. Consequently, safety precautions should always be taken when working with fiber optic materials to prevent injuries. Proper handling and disposal practices are essential to mitigate the risk associated with glass shards from fiber optic cables.
