What is a common precaution when handling graphite or carbon/epoxy composite materials?

• A. Exposure to loud noise
• B. Irritation of the skin from fibrous particles
• C. Risk of chemical burns
• D. Heat exposure

Answer: (B)

When handling graphite or carbon/epoxy composite materials, a common precaution is the irritation of the skin from fibrous particles. These materials often contain small, lightweight fibers that can become airborne during cutting or sanding processes. When these fibers come into contact with the skin, they can cause irritation and, in some cases, allergic reactions. This is why it is critical to wear appropriate personal protective equipment, such as gloves and long-sleeved clothing, to prevent skin exposure.

Understanding this precaution can help ensure the safety and health of personnel working with these materials in an aviation environment, where such composites are commonly used due to their favorable strength-to-weight ratios.
