What safety measure is recommended when working with composite matrix?

• A. Use a respirator
• B. Work without protection
• C. Only gloves are needed
• D. Ignore fumes

Answer: (A)

Exposure to resin fumes and sanding dust from composite matrices can irritate the lungs and over time cause more serious health effects. A respirator directly reduces what you breathe, filtering out volatile organic compounds and fine particles so inhalation hazards are less likely to affect your airways. Gloves or goggles protect skin or eyes, but they don’t address inhalation risk, and ignoring fumes leaves your respiratory system exposed. When selecting a respirator, choose one suitable for organic vapors used with your resin system, and add a particulate filter if sanding will create dust. Ensure a proper seal, follow the manufacturer’s guidance, and use in a well‑ventilated area or with local exhaust. This combination addresses the main route of exposure while supporting other protective gear.
