Be alert, Be alert,

pay attention, pay attention,

and and

proceed with caution!proceed with caution!

#1 Be prepared to work when you arrive at the lab.

Study the lab procedures before you arrive.

If you have any questions, ask your teacher.

It is better to ask a question than to perform a lab experiment wrong and/or cause damage to someone or something.

#2 Perform only authorized activities or experiments.

Never do anything in the laboratory that is notcalled for in the lab instructions or by your teacher.

Always read your lab instructions carefully and always performlabs exactly as instructed.

Not following instructions can result in injuries and accidents.

#3 Goggles should be worn at all times when the lab experimentrequires the use of chemicals or open flames.

Chemicals can splash when being poured and glassware canshatter permanently damaging your eyes. If you get a chemical in your eyes, rinse your eyes for 15 minuteswith running water.

Aprons protect clothes from chemicals such as bleach.

and and proceed with caution!proceed with caution!

#4 Never eat or drink in the lab—not even water.

Do not use laboratory glassware as a container for food or drink.

Many chemicals used in lab are toxic.

Eating food from countertops or glassware used in labs canresult in the ingestion of poisonous chemicals.

#5 Never taste or directly smell any chemical or substance in the lab.

Inhaling fumes can destroy the lining of your nose and/or throat and introduce chemicals into your bloodstream.

If you need to smell something, use your hand to waft some of the odors from the top of the container toward your nose, BUT only when instructed to do so.

#6Always point open containers and test tubes AWAY fromyourself and others when heating.

Hold test tubes slanted and move back and forth over the flame.

Heated substances may boil out and splatter onto your skinand/or others resulting in burns and damage to eyes and skin.

#7 Report ALL injuries and accidents immediately to the teacher.

No matter how small or insignificant it may seem, let your teacher know immediately about any problems or accidents in the lab.

#8 Long hair must be tied back. Loose dangling jewelry must be removed. Long, dangling sleeves should be secured as well. Remove ties and bulky jackets. During dissection labs, no open-toe shoes allowed.

Long hair, dangling jewelry and loose clothing can easily catch fire when exposed to an open flame. Also, loose clothing can trap chemicals next to your skin resulting in burns.

Hair upClosed -toed shoes

Dress appropriately for lab.

#9 Know the location and proper use of the fire extinguisher, fire blanket, eyewash station, first aid kit, emergency call button andother safety equipment.

When putting out an alcohol fire in the lab always use a CO₂fire extinguisher.

Never use a fire extinguisher on a person.

#10 If you spill chemicals, WASH if off immediately with water and tell the teacher.

Spilled acid should be cleaned up with a base, such as baking

soda. Spilled bases should be cleaned up with an acid, such as

vinegar.

#11 Never leave a flame unattended.

If a fire should break out in the classroom or if your clothing should catch fire, smother it with a fire blanket or coat. NEVER RUN!NEVER RUN! Running provides oxygen to a fire causing it to flame up.

The best way to put out a fire is to remove the oxygen from it by smothering it.

Stop Drop and Roll

#12 Always leave your lab station clean. After each lab wash or clean all used equipment and return it to its proper place.

Dispose of chemicals and glass in the proper containers.

Be sure to wash your hands before leaving.

Chemicals should be disposed of in proper waste containers.

Never pour chemicals down the sink unless your teacher tells you thatyou can.

Broken glass should be placed in a specially labeled container to prevent injury.

Turn off gas and unplug electrical appliances.

#13

No horseplay in the lab.
