What are the important safety steps when using a centrifuge?
Do not stick your finger into it. Make sure the test tubes are balanced.
At any time, if something is broken, get the teacher. I will clean it up so that you will not get hurt.
Lets say that you are boiling some water. You are using a Bunsen Burner to boil the water. The beaker breaks and water pours out putting out the fire. What should you do first?
Turn off the gas.
If when performing an experiment, some solution goes into your eye. What first aid technique should you do?
Use the eye wash
What should you ever do if you should spill some solution?
Get the teacher. I will clean it up so that you will not get hurt.
You are using a funnel. You are pouring something into it. The liquid is not going down. What should you do first?
Lift up the funnel. There may be an air lock. This prevents the air from escape, so the liquid cannot go into the bottle.
What is the most important safety technique when using a scalpel?
Cut away from yourself and others
Make sure to clean and dry your area before you leave the lab. Make sure to clean and dry up your equipment before you leave the lab. Make sure you put everything away before you leave the lab.
Do not wear baggy cloths. You do not want the cloths to hang down so they knock over equipment. You also do not want your cloths to get into chemicals and soak them up.
Do not wear really nice cloths. You may get something on your cloths that might ruin them. So wear cloths you do not mind spilling something on them.
If you have long hair, be careful. When you turn, you may knock equipment over. You may also get some of your hair into some chemicals. You need to put your hair up before lab.
Wear Safety Goggles
Be well behaved while in the lab. Do not run around the lab. Do not get on top of the lab table. Do not throw anything.
Why do you have to be careful with a Mercury Thermometer?
Mercury is a toxic liquid which easily soaks into your skin. If too much gets into your system, then it can cause nerve damage or brain damage.
Be very careful with the sinks in the lab. If you turn the water on too quickly, then water will go all over the place. So turn the water on slowly.
When washing your hands, it is best to use the wash room. It is the room in the back of the lab on the left side. Do not use the sink behind the door. Use the custodian's sink.
When mixing chemicals that produce a toxic fume, where should you mix these chemicals?
Chemical Hood
The main lab contains optic shades. The shades should remain closed at all times. Only the teacher should open them.
The stools in the lab are old, so that squeak when you turn in them. Do not turn in them.
The lab table are also very old. Do not open the drawers or cabinets. You have no purpose in them.
Do not go behind the teacher table. It is off limits. You have no purpose back there.
Make sure you are quiet when I am talking. The teacher may tell you a safety warning. You might miss it if you are talking. Also, you might be informed of something you need to do first.
Do not eat or drink in the lab. You do not know if some chemical came in contact with the food or liquid. So do not take a chance.
Do not goof off in an outdoor lab. Do not run, throw rocks, or throw water. Behave yourself very well.
When showers are available in lab, they are to be used in case a lot of strong acid or strong base is spilled on you. The water dilutes it.
Red indicates how easy it catches on fire. 4 means easily catch on fire while 0 means no problem.
Yellow indicates how reactive the substance is. A lot of times water is something it is reactive with. Some chemical react with air. Also 0-4 rating.
Blue indicate health hazard. 4 means very bad for your health.
White represents a special hazard. This area will have writing. Could be for oxidizers, acids, bases, or corrosive materials.
When using pipets, do not use your mouth to suck up the liquid. Use a bulb.
Do not add water to acid when mixing. There could be a reaction. Always add acid to water. That way the acid is diluted.
Always read the lab instructions carefully before you start. You might miss something if you do not read first.
When using hoses for what ever reason, make sure they are connected well.
Make sure to label all storage containers when performing an experiment. Never use a bottle that is not labeled.
If you are not sure what a substance is, do not smell it to find out. You may burn off your olfactory senses.
If you have any questions at any time, then ask the teacher. Do not continue if you are not sure what to do.
I take lab safety very serious. Act right and do what you are supposed to do. Other wise you may lose you lab privilege.
