Do Wear Eye Protection
Science labs contain glassware, caustic chemicals, vapors, open flames and other substances that may harm your eyes. Goggles or safety glasses help protect your eyes in case of accidents or spills.
Do Practice Fire Safety
Open flames from Bunsen burners or alcohol lamps are necessary for experiments that involve heating, boiling and burning chemicals or other specimens. Keep your hands and arms away from the open flames, wear safety glasses, tuck in loose clothing, and keep long hair tied back.
Do Handle Glassware Safely
Eliminate potentially dangerous chemical reactions by thoroughly washing beakers, test tubes, flasks and other glassware before and after use. This also helps ensure that results are not tainted by chemical residue from previous experiments. Glassware can break, leaving behind potentially harmful shards. Report any broken glass immediately and dispose of it properly.
