Most people think about eye damage when it comes to safety in fiber optic installation because of the laser light traveling inside the fiber, but there are other hazards of which you should be aware. The broken ends of fibers and scraps created from the splicing process can be extremely dangerous. The ends are very sharp, so they can easily penetrate your skin. They can break off without your knowledge. They can also be hard to find and remove. Sometimes, a pair of tweezers and a magnifying glass will get them out. But most of the time, you will have to wait until the area gets infected so they can work themselves out.
