Expert's answer

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.

Do not Eat or Drink in the Lab

Eat before entering or after leaving the lab. Food, gum, mints, cough drops and beverages are messy. They may get equipment dirty, contaminate samples, absorb chemicals or cause accidents.

Do not Use Excessive Force

Some experiments require connecting glassware with glass tubes and rubber grommets or plugging glassware with stoppers. Using excessive force can potentially chip or break the glass.

Sterilization is any of a number of medical methods of birth control that intentionally leaves a person unable to reproduce
