♦ Wear approved safety goggles as directed. Goggles should always be worn in the laboratory, especially when you are working with a chemical, a chemical solution, a heat source, or a mechanical device.
♦ In case of eye contact, do the following: Go to an eyewash station immediately, and flush your eyes (including under the eyelids) with running water for at least 15 minutes. Hold your eyelids open with your thumb and fingers, and roll your eyeball around. While doing this, have another student notify your teacher.
♦ Do not wear contact lenses in the laboratory. Chemicals can be drawn up under the contact lens and into the eye. If you must wear contacts, tell your teacher. You must also wear approved eye-cup safety goggles to protect your eyes.
♦ Do not look directly at the sun through any optical device or lens system or reflect direct sunlight to illuminate a microscope. Such actions concentrate light rays to an intensity that can severely burn your retina and that may cause blindness.
