Lock Down

In the classroom

Go to the front of the room near the teacher table. Sit in

the floor.

No Talking

If there is ever a time that a lockdown is called and you are not in the classroom.

Then hide in the bathroom. You will not be let into any

classroom.

What should you do if you were to catch one of your

sleeves on fire?

Stop, Drop, and Roll. Partner inform the teacher. Wrap fire blanket around

person on fire.

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 camein 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 alot 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.
