Cuts and Burns

• These are the two most common injuries…• Cuts can be prevented by checking to see if

glassware is chipped, or broken…also clean up any glass you break. – Allow to bleed briefly…..wash with soap and

water

So you burned yourself……

Tell Mr. Jorden

Immediately put the burned area under cool water until the burning sensation subsides.

Someone has fainted???

Give the person fresh air!

Make sure their head is lower than the rest of their body.

If the person does not recover then artificial respiration may be needed.

SMALL FIRES on counter

In order to put out a small fire in the laboratory you must place an over turned beaker on top of the fire.

It cuts off the supply of oxygen.

FIRE!

In case of a small fire, such as a beaker engulfed in flames…

FIRE!

You should cover the beaker with a watch glass and leave the cover there until the flame dies out.

In case of a large fire…

use a fire extinguisher to put out the flame …

USING A FIRE EXTINGUISHERPull pin

Aim

Squeeze handle

Move back and

forth

If a person catches on fire….

Wrap them in the nearest fire blanket.

Fire Blanket

• Use the fire blanket when a person catches on fire

• If someone catches on fire, wrap them up in the blanket and put them on the ground

• Do NOT cover up the persons head with blanket, it does not let oxygen through

Chemistry Safety Notes

If you forget your safety glasses, bad things, like blinding an eye, could happen

See how UNcool he looks from

his eye injury

IF YOU SPILL A CHEMICAL…

• If you spill a chemical in your eyes, immediately use the eyewash fountain to wash the liquid from your eyes

• Remember, if you have contacts take them out before you use the eyewash fountain.

• DO NOT RUB EYE!! (a foreign object could scratch your eye!)

In Case You are Poisoned...

• IMMEDIATELY– Identify the chemical

substance you ingested– Notify the teacher– If necessary, contact

medical assistance

Poison

Sometimes we may have to force you to vomit.

Are you bleeding severely?

Apply pressure to the wound and get medical attention immediately.

If harmful chemicals were to make contact with your skin…..

Make sure the teacher is notified as you rinse it off in the sink right away.

If it is a larger spill on your clothes and can’t be reached by the sink, take your clothes off immediately and if it made contact with skin get under shower.

Neutralize acids with baking soda and neutralize bases with boric acid.

Be Prepared

• When you come to class be prepared to to immediately begin the lab.– Familiarize yourself

with the lab procedures before beginning the lab.

• Perform only those lab activities assigned by Mr. Jorden.

• Never do anything that is not called for in the laboratory procedure or by your teacher.

Chemistry Safety Notes

Work areas should be clean and tidy

DO NOT take other materials into the laboratory.

Chemistry Safety Notes

DO NOT wear open toed shoes

However fashionable they may be

Always wear closed-toe shoes

WRONG!

OUCH

SANDALS cont’d…

Some people don’t listen and this is the outcome

Attractive !!

HAIR

If you have long hair tie it up, if you have a long beard tie it up and put it over your

shoulderMr. Jorden has extra hair ties on his desk.

Chemistry Safety Notes

If you forget to tie back hair, it could catch on fire.

Looks like it hurts too!

Always wear safety goggles

WRONG!

GOGGLES cont.

Or this could happen

Before you start your lab also make sure that you are wearing

an apron

This will prevent harmful chemicals from spilling on your skin or ruining

your clothes

APRON

Always wear your apron….

Set-up apparatus as described

• Never use makeshift arrangements.

• ALWAYS use the prescribed instrument (tongs, test-tube holder, forceps, etc.) for handling apparatus or equipment.

Keep all combustible materials away from open

flames….You might accidentally set

your homework on fire.

Pre-Lab

Never Touch or taste any substance in the lab unless instructed to do so.

Never put your face near the mouth of a container that is

holding chemicals

Always smell chemicals with a wafting motion

ALL RIGHT!

WRONG!

How to Sniff in the Laboratory

You should never place your nose directly above an apparatus in order to smell the odor of the contents.

Look what happened to little Jonny!

The Right Way

Always waft in order to smell a substance

Clean up all spills immediately

If a harmful chemical is spilled and not cleaned up, the next person to encounter it

could be harmed!

WHEN MR. JORDEN IS OUT

When the teacher is knocked out …

JORDEN cont.

Call one of these numbers for help

Do not return used chemicals to their original containers

When mixing an acid and water…

always add the acid to the water

ACID

H20

Chemical Spills (continued)

• If you spill a chemical on yourself, wash the area well with soap and water, tell your teacher, and seek medical attention if needed.

• If a chemical spills on your clothes, take them off and wash yourself off with the safety shower.

HANDLING GLASSWARE• Always carry glass pieces in

a vertical position to avoid stabbing anyone.

• Never handle broken glass with your bare hands. Use a brush and dustpan to sweep up the broken glass.

• Always lubricate glassware.

Incorrect Procedure

Never try to force glass tubing through an aperture without lubricating the end of the glass tubing, as well as the hole into which it will be inserted. Also, do not press with your palms, as illustrated to the right – doing so may cause the tubing to break or impale/cut you.

Proper Procedure

LUBRICATION

Glass tubing lubrication Lubricating the stopper

Consequences of Recklessness

This happens when you are not careful

Allow plenty of cooling time before touching glass

PATIENCE, MY FRIEND!

WRONG!

Checking Heat

Don’t grab an object that

has recently been heated.

Always use the back of your

hand to determine if an object is

still hot after removal from

a flame.

This is what happens when you aren’t careful!

When heating liquids in test tubes using a burner….

Be sure to tilt the test tube away from you

-NEVER heat anything unless instructed to do so.

-NEVER look into a container that is being heated.

-When heating a substance in a test tube, make sure that the mouth of the tube is pointed AWAY from yourself or others.

Heating Substances

The First Test- Conclusions

Never heat a CLOSED CONTAINER!!!!

The End!
