The issue of personal health and safety is paramount when working with composite materials. Following these safety precautions may prevent future health problems, such as those encountered in the case of asbestos fibers. These particles are generated by drilling, sanding, routing, or sawing the composite structures. Respiratory protection is required in those operations where dust exists or is generated. Eye protection, consisting of safety goggles or a face shield, is also recommended for use in work involving any operation where the likelihood of airborne fibers exist.
Broken fibers can penetrate the skin.
The fibers may become lodged beneath the skin. These fibers are so brittle and difficult to remove that they generally have to be cut out and the wound disinfected to prevent infections. Personal hygiene includes washing your hands before and after working with composites, and your hair should be washed at the end of each day. Wash dust-contaminated clothing separate from other clothing. Do not eat, drink, or smoke in the composite repair area.
