Do's And Don'ts in the Chemistry Laboratory

Do Wear Eye Protection

Do Practice Fire Safety

Don't Use Excessive Force

Don't Eat or Drink in the Lab

Don't Leave A Mess

+iScience 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.

+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.

Write proper laboratory procedures, observations and instructions in a laboratory notebook, with permanent binding and large pages. Lab notebooks help keep track of data, maintain records of experiments and facilitate thinking.

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.

Clean up spills immediately. Cover the spill with paper towels and then wipe it up from the outside in, pushing the mess toward the center of the table, rather than the floor. Dispose of the paper towels in a proper container. Clean up all laboratory equipment, materials, supplies and work surfaces before leaving the lab. Make sure Bunsen burners and other sources of heat or gas are properly turned off.

Do Keep Notes

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.
