LAB SAFETYPlease Pay Attention

WARM UP List 5 classroom expectations that you

learned on Wednesday.

LABORATORY SAFETY If you see anything in the classroom/lab that

is dangerous, tell the teacher at once. Rags or paper towels with flammable liquids

or solids on them must be put in a designated container with a lid.

Spills can cause injuries and accidental accidents. Always clean them up at once.

LABORATORY SAFETY Alcohol, ether, and other volatile materials

that can ignite easily should never be used near an open flame.

When you work with laboratory chemicals and Bunsen burners, long hair must be tied back.

LABORATORY SAFETY If you think there is something wrong with a

piece of equipment you are using, stop, turn it off, and tell the teacher.

If you break a piece of glassware or other equipment, tell the teacher at once.

If you see a fire in an apparatus assembly or a burning liquid such as alcohol tell your teacher immediately.

LABORATORY SAFETY To put out a fire in a person’s hair or clothing,

use the fire blanket. To prevent accidents during lab activities

with chemicals and equipment, you should follow directions.

Playing (as opposed to working) in the laboratory or bothering another person is always against the rules.

LABORATORY SAFETY To be able to put out a fire quickly and safely,

you should know how to use extinguishers, who is responsible for using the extinguishers, where the extinguishers are located.

If flammable liquids such as alcohol are spilled clean them up at once and tell the teacher immediately.

LABORATORY SAFETY Laboratory Safety When hooking up electrical equipment your

hands must be dry. Cabinet drawers and doors that are left open

cause a hazard and should be closed by you. In case of fire in the laboratory, notify the teacher

at once and then follow the teacher’s directions.

Laboratory Safety All chemicals should be stored in properly

labeled containers. When diluting acids, the proper procedure is

adding acid to water.

LABORATORY SAFETY If acid gets on your skin or clothes, wash at

once with plenty of running water. Spilled acids can be made safe (neutralized)

with baking soda. Spilled bases can be made safe with

vinegar.

LABORATORY SAFETY You must wear approved eye protection while

in the laboratory as directed by the teacher.

You should prepare for each lab activity by reading all instruction before you do the experiment.

LABORATORY SAFETY When measuring small amounts of liquids

with a pipet, draw the liquid up into the tube by using a rubber suction bulb or pump.

When heating substances in a test tube, be sure the open end of the bulb points toward no other person.

LABORATORY SAFETY To remove an electrical plug from its socket,

you should pull on the plug itself. When using chemicals and equipment be

sure to read labels. Food and drink are permitted during a lab

activity, never

LABORATORY SAFETY If you want to smell a chemical waft the

odor toward your nose. When working in the lab, don’t rub eyes,

don’t touch your face, wash your hands at the end of the lab.

When there is a fire drill you should know the proper procedures

LABORATORY SAFETY When cleaning up, put chemicals into

designated containers

LABORATORY SAFETY Science is a hands-on laboratory class.

Students will be doing many laboratory activities which require the use of chemicals. Safety in the science classroom is the #1 priority for students, teachers, and parents. To ensure a safe science classroom, a list of rules has been developed and provided to you. These rules must be followed at all times.

LABORATORY SAFETY I have a no tolerance for inappropriate

behavior during a laboratory activity. Students will be asked once to stop the inappropriate behavior. The second time it occurs the student will be asked to stand in the hall until the activity is complete
