Lab safety worksheet
What type of eye cover is acceptable to wear during chemistry lab
Approved safety goggles only
Measuring approximate amounts of liquid
Beaker, Florence, dropper, flask
Dropping small quantities of liquids into test tubes
Pipette, dropper
List as many proper and improper lab procedures as you can in this picture
Proper: gloves on, hair pulled back, walking, closed toe shoes, apron Improper: moving hot chemicals, smoke going over head, unattended materials
where do you dispose of waste material from the lab
Where the teacher tells you.
Holding 50 mL of boiling water
beaker, Florence flask
Holding hot objects in flame
tongs, ring sand, clay triangle, crucible
Rinsing out glassware with distilled water
water bottle
What kind of injuries should be reported to your teacher
All injuries
Pouring 50 mL of liquid from one container to another
Beaker
What should you do with your waist chemicals from your lab when you are done before performing the experiment
Deposit in appropriate waste speakers in front of the room, unless your teacher tells you it is OK to pour the contents down the drain
If your clothing or your neighbors clothing catches fire what should you do
Drop to the floor and rolled to the fire extinguisher
Transferring small quantities of liquid solutions from one container into another
Dropper, pipet, wash bottle
All accidents and/or injuries in the science lab should be handled by the students themselves
False
It is OK to point The open end of a test to being heated at yourself or someone else
False
Long hair (not tied back), dangling jewelry, and loose clothing are cool in science labs
False
When you're moving an electrical plug from a socket pull on the electrical cord
False
heating a dissolute substance in water to drive off the water
Florence flask, beaker, evaporating dust, Bunsen Burner, hot plate
Protect your eyes from splattering solids and splashing liquids
Goggles
If something on your lab benches catches fire, what is the best response from the Choices below
If and only if it is possible to do so safely, cover the flames with a beaker or watch glass, remove solvents from the area, then get the fire extinguisher; if it is not possible to do this, please leave the room and pull the fire alarm, and call 911 from a safe phone
You may remove your goggles while in the lab room
If no one is doing an experiment are washing glassware
Broken glassware left around the lab is a hazard because
If on the floor, someone might step on it and cut their foot, if on the lab bench, someone might lean on the bench and cut their arm, and if in the sink, someone might try to pick it up to throw it away properly and cut themselves
You can save the wear contact lenses while doing a chemistry lab
If you are wearing wearing goggles
You get a chemical in your eye. What should you do
Immediately flush with water, continue washing for 15 minutes and tell your teacher
If you spill an acid or base on yourself, you should
Immediately wash with soap and cool water and tell your teacher.
What kind of wastes should be put into the broken glass container
None
In the lab, what should be done with hair that is longer than shoulder length
Should be pulled back
Removing solid chemicals from a reagent bottle
Spatula
You cut your palm on a small piece of broken glass that is lying on a bench lab
Tell your teacher
Your lab partner notices a tiny crack in a beaker that you were heating over a Bunsen burner
Tell your teacher
Your shirt catches fire while leaning over a Bunsen burner
Tell your teacher
A drop of a chemical solution splashes in your eyes
Tell your teacher and flush your eyes with running water for at least 15 min
Holding a test over a Bunsen burner for heating
Test tube clamp
These 5 pieces of lab equipment would hold a test tube in a beaker of bowling water above a Bunsen burner
Test tube holder Test tube clamp Ring stand Wire gauze O ring clamp Wash bottle
Anytime chemicals, heat or glassware are used, students need to wear lab goggles
True
The correct procedure for smelling a chemical is the point the face of the container away from your face (and others' faces), well gently feigning the vapors towards your nose
True
When dissecting, be sure to hold the specimen securely and cut away from yourself
True
When you complete your experiment, it is all right to do your own experiment as long as you clean up afterwards
True
Describe how you would test the odor of any chemical in the lab
Wafting
Covering a beaker a bowling water prevent splattering
Watch glass, wire gauze
You have looked up the hazards of the chemicals you will be using in a particular lab, and found out that they are mild health hazards, requiring you to avoid skin contact and vapor elation. Therefore, when in lab
Wear Long pants, close toed shoes, a lab apron, gloves
When should I safety goggles or glasses be worn in the lab
Whenever you are doing an experiment
Measuring exactly 43 mL of water
graduated cylinder
Heating substances to a constant temperature
hot plate
If a fire alarm sounds you should
leave the building immediately following fire alarm protocols
Determine if water is boiling
thermometer
