Which rule helps prevent eye exposure in the lab?

• A. Do not put anything in your mouth
• B. Always wear goggles
• C. Cap flasks
• D. Use a dustpan

Answer: (B)

Eye protection is essential because eyes are directly exposed to splashes, fumes, and debris in the lab. The best rule to prevent eye exposure is to always wear goggles. Goggles create a barrier around the eyes and, when properly fitted with side shields, protect from splashes from any direction. They keep hazardous liquids and particles away from the eyes and help maintain visibility by staying clear and providing a secure seal.

Other habits like not putting anything in your mouth, capping flasks, or using a dustpan are important for overall safety, but they don’t provide a direct shield for the eyes. Wearing goggles specifically targets eye protection, which is why it’s the most effective rule for preventing eye exposure. If something splashes, remember to use the eyewash station to rinse promptly.
