Wearing contact lenses in the laboratory is forbidden because chemical vapors and other foreign materials can be trapped against the cornea and cause eye damage, including blindness. All persons in the laboratory including visitors must wear safety goggles. Ordinary prescription glasses are not adequate protection. Even safety glasses with side shields do not completely protect against splashes. Specialized glasses should be worn when working with ultraviolet light, lasers welding, glassblowing, etc.
Gloves provide a protective barrier between the substances being handled in the lab and the skin.
Make sure you wear the right type of glove for the job. Some chemicals are incompatible with the material used to produce the glove. Ask the chemical safety Officer or your instructor if you need assistance. Check the gloves to ensure the absence of cracks or small holes. To prevent the contamination of the lab environment remove the gloves before leaving the work area, and before touch the phone, doorknobs, pencils etc.
