Carelessness

Insufficient knowledge

Taking unnecessary risks

Being in too great a hurry

Reading all procedures so you know what you are going to do

Following the procedures as they are written (Do not do “extra” experiments just for fun. The results may be dangerous or even deadly.)

Immediately report any accident or injury, no matter how minor, to your teacher

Take this seriously

Fill out the answers to the questions

Follow the teacher’s directions and do not perform any experiment the teacher has not authorized

Remember that the human body is a conductor of electricity

Never use electrical equipment with which you are not familiar or that contains no directions to follow

Hands and work areas, including floors and tables, should be dry

Never overload a circuit Watch for exposed wires Make sure all electrical equipment is properly

grounded

Never force glass tubing into rubber stoppers

Never pick up broken glass with your bare hands

Allow heated glassware to cool before touching it

Never taste chemicals as a means of identification Do not breathe fumes directly Do not eat or drink in the laboratory Do not eat or drink from laboratory glassware Never handle mercury Label reagent bottles properly Read bottle labels carefully Wash hands thoroughly after experiments If any chemical comes in contact with your skin,

rinse area with plenty of cold water and notify the teacher

If any substance, liquid or powdered, splashes or blows into your eyes, wash them out immediately with water and notify your teacher

Wear safety goggles when necessary All laboratories should have an emergency

eye-wash station; know its location Wearing contact lenses, even with goggles,

is dangerous; fumes from chemicals can get under the lenses, causing eye damage

Fire extinguishers and fire blankets should be available

Turn off hot plates or burners when not in use Tie back hair and loose clothing Use proper procedures when lighting

laboratory burners In case of fire, smother flames with a cloth or

fire blanket When heating the contents of a test tube,

point the tube, away from yourself and others

Take great care in noting odors or fumes; use a wafting motion of the hand

Use volatile liquids only in very small quantities and in a well ventilated room

Do not breathe pure gases such as hydrogen, argon, helium, or nitrogen (high concentrations of CO2 can also be dangerous)

Turn off gas valves when not in use

Confine loose clothing

Wear laboratory aprons

Use safety shields or screens if there is a potential danger of an explosion or implosion of apparatus

Never use an open flame when working with volatile liquids such as alcohol

Always use single-edged razors; double-edged razors are too dangerous

Handle any sharp instrument with extreme care; never cut any material towards you, always cut away from you

Notify your teacher immediately if you are cut in the lab

Take particular care to handle glassware safely, and never use broken glassware

Never heat glassware that is not thoroughly dry; never pick up any glassware unless you are sure it is not hot; if it is hot, use heat-resistant gloves or beaker tongs

Always clean glassware thoroughly before putting it away

Fire polish ends of glass tubing; do not force glass tubing and funnels into rubber stoppers; glass tubing should be wrapped in toweling when being inserted or removed from rubber stoppers; a lubricant (glycerin or stop cock grease) is always used

If any substance splashes or blows into your eyes, what should you do?

What kinds of safety apparel do you wear in the science laboratory? If your partner wants to perform an experiment that he/she thought

up, what should you tell him? Before leaving the laboratory for your next class, what should you

do? A chemical solution has spilled on your skin. What is the first thing

you need to do? Draw a floor plan of your classroom and identify the location of the

eyewash fountain, fire blanket, and fire extinguisher. If your hair is long, what precautions will you take in the laboratory? What does wafting mean? Why is a lubricant used when inserting glass tubing into a rubber

stopper? List four main causes of laboratory accidents.
