Why even worry about all this lab safety stuff?

Sodium Hydroxide to the skin

Ammonia in the eye

Page 3: Laboratory Safety & Procedures

Broken equipment

Cuts

Fires

Page 4: Laboratory Safety & Procedures

Ruined experiments

Page 5: Laboratory Safety & Procedures

Only YOU can prevent lab accidents!

Inform teacher IMMEDIATELY of any mishap—fire, injury, breakage, spills, etc.

•Horseplay is NEVER allowed in the laboratory.

Page 6: Laboratory Safety & Procedures

Horseplay is NEVER allowed in the laboratory.

Page 7: Laboratory Safety & Procedures

How to prepare yourself for lab:

Do NOT wear clothing that is loose enough to catch on anything or on fire.

Page 8: Laboratory Safety & Procedures

Do not wear sandals or open-toed shoes.

Wear protective equipment as directed by lab instructions/instructor (goggles, apron, gloves, etc.)

Page 9: Laboratory Safety & Procedures

Always wear goggles when using chemicals and

throughout the entire cleanup and hand washing process.

Keep your hands away from your face when working in the laboratory.

Page 10: Laboratory Safety & Procedures

Remove synthetic fingernails before working in the lab (highly flammable)

Do NOT use hair spray, mousse, or other flammable hair products just before or

during laboratory work where an open flame is used (highly flammable)

Page 11: Laboratory Safety & Procedures

Tie back long hair and loose clothing to keep them away from flames and equipment.

Remove loose jewelry (i.e., chains and bracelets) while doing lab work.

Page 12: Laboratory Safety & Procedures

NEVER eat or drink while in lab.

Do NOT directly inhale vapors or taste, touch or

smell any chemical or substance unless

instructed to do so by your teacher. Then waft, if

instructed.

Page 13: Laboratory Safety & Procedures

When you are working:Read all instructions before you begin a lab or field activity. Ask questions about what you do not understand.

Page 14: Laboratory Safety & Procedures

Work ONLY on activities assigned by the teacher.

Page 15: Laboratory Safety & Procedures

Do NOT substitute other chemicals or other substances for those listed in activity.

Do NOT begin until directed to do so by teacher.

Do NOT handle any equipment without specific permission.

Page 16: Laboratory Safety & Procedures

Remain in your own work area unless given permission by the teacher to leave it.

Page 17: Laboratory Safety & Procedures

Do NOT take any materials or chemicals out of the classroom.

Stay out of storage areas unless you are instructed to be there.

Page 18: Laboratory Safety & Procedures

Do not use unlabeled chemicals.

NEVER work alone in the laboratory.

Page 19: Laboratory Safety & Procedures

About Clean Up

Keep work and lab area clean.

Page 20: Laboratory Safety & Procedures

Turn off all burners and other equipment before

leaving the lab.

Carefully dispose of waste properly.

Page 21: Laboratory Safety & Procedures

Wash your hands thoroughly with soap and warm water after the labs.
