Safety Symbols

These symbols warn of possible dangers in the

laboratory and remind you to work carefully.

Safety Goggles Wear safety goggles to

protect your eyes in any activity involving

chemicals, flames or heating, or glassware.

Lab Apron Wear a laboratory apron to

protect your skin and clothing from damage.

Breakage Handle breakable materials,

such as glassware, with care. Do not touch

broken glassware.

Heat-Resistant Gloves Use an oven

mitt or other hand protection when handling

hot materials such as hot plates or hot glassware.

Plastic Gloves Wear disposable plastic

gloves when working with harmful chemicals

and organisms. Keep your hands away from

your face, and dispose of the gloves according

to your teacher's instructions.

Heating Use a clamp or tongs to pick up

hot glassware. Do not touch hot objects with

your bare hands.

Flames Before you work with flames,

tie back loose hair and clothing. Follow

instructions from your teacher about lighting

and extinguishing flames.

No Flames When using flammable

materials, make sure there are no flames,

sparks, or other exposed heat sources present.

Corrosive Chemical Avoid getting acid

or other corrosive chemicals on your skin or

clothing or in your eyes. Do not inhale the

vapors. Wash your hands after the activity.

Poison Do not let any poisonous chemical

come into contact with your skin, and do not

inhale its vapors. Wash your hands when you

are finished with the activity.

Fumes Work in a ventilated area when harmful vapors may be involved. Avoid inhaling

vapors directly. Only test an odor when directed

to do so by your teacher, and use a wafting

motion to direct the vapor toward your nose.

Sharp Object Scissors, scalpels, knives,

needles, pins, and tacks can cut your skin.

Always direct a sharp edge or point away from

yourself and others.

Animal Safety Treat live or preserved

animals or animal parts with care to avoid

harming the animals or yourself. Wash your

hands when you are finished with the activity.

Plant Safety Handle plants only as

directed by your teacher. If you are allergic to

certain plants, tell your teacher; do not do an

activity involving those plants. Avoid touching

harmful plants such as poison ivy. Wash your

hands when you are finished with the activity.

Electric Shock To avoid electric shock,

never use electrical equipment around water, or

when the equipment is wet or your hands are

wet. Be sure cords are untangled and cannot

trip anyone. Unplug equipment not in use.

Physical Safety When an experiment

involves physical activity, avoid injuring yourself or others. Alert your teacher if there is any

reason you should not participate.

Disposal Dispose of chemicals and other

laboratory materials safely. Follow the

instructions from your teacher.

Hand Washing Wash your hands thoroughly when finished with the activity. Use

antibacterial soap and warm water. Rinse well.

General Safety Awareness When

this symbol appears, follow the instructions

provided. When you are asked to develop your

own procedure in a lab, have your teacher

approve your plan before you go further.

Answer 4

Personal Safety:

• Wear goggles and an apron anytime you are working with dangerous chemicals, hot liquids or solids, and other potential sources of splashes, splattering or spills.
• Goggles must be worn anytime a Bunsen burner is used.
• Make use of any safety equipment such as beaker tongs, test tube clamps, thermal gloves, etc. when handling hot beakers, test tubes or other containers.
• Do not wear a coat or jacket during a lab. Necklaces and bulky jewelry should be removed. These items tend to get in the way when reaching for objects and can get caught in moving parts such as motors.
• Do not perform any experiment that is unauthorized.
• Study your lab assignment/experiment before you come to class. If you have any questions, ask the instructor for help.

Bunsen Burner Safety:

• A bunsen burner flame is very hot. The center of the flame will be over 1000 degrees Celsius. Treat burner flames with respect.
• Always use the main gas shut off valve on the desk to shut off a bunsen burner. The valve at the base of the burner is only used to control the flame.
• If your hair or clothing catches on fire stop drop and roll.
• If someone else's hair or clothing catches on fire, wrap them with a fire blanket to smother the fire. Do not let them run.

Safety Equipment:

• Know the location of the fire extinguisher, safety shower, eye wash station, first aid kit, bihazardous cleanup kit, fire blanket, fire alarm switch, and office call button .

  fire extinguisher - next to science room door

  safety shower - DR. Dean Noel Mercado - Rm 105

  eye wash station - teachers desk faucet

  biohazardous cleanup kit - on shelf inside storeroom door

  first aid kit - wall by science room door

  fire blanket - wall by science room door

  fire alarm switch - in hallway beside SW entrance outside science rooms

  office call button - below white dry-erase board at front of classroom

Safety with chemicals and dissecting specimens:

• Do not touch or taste any chemical unless specifically instructed to do so.
• Read chemical labels more than once before using the contents - it is easy to confuse chemicals.
• When working with chemicals or dissections, keep your hands away from your face. The skin on your face is much more sensitive to irritation than your hands.
• To smell something, hold it away from your nose and wave your hand over it towards your nose. You may pass out or inhale dangerous gases is you just stick your nose over the container and breath in.
• Flush any chemical spill on your skin with plenty of water. The rule of thumb is 15 minutes.
• When heating anything in a test tube, point the mouth of the test tube towards a wall, away from people.
• Do not lay the glass stopper from a reagent bottle on the lab table. Hold the handle of the stopper between two fingers while you pour from the bottle.
• When mixing acids and water, pour the acid into the water. Remember, AnW (root beer)
• Wash your hands when you are finished with the lab.

Safety with glassware & broken glass

• Never use chipped or broken glass. If you notice chipped or cracked glassware during a lab please report it to the instructor to be replaced.
• Broken glass should never be handled with your hands. Use a dustpan and broom to sweep up broken glass. Small pieces can be wiped up using a wet paper towel.
• Broken glass should be placed in the proper container - either a can for broken glass or a sharps container.
• Always have the instructor clean up a broken mercurythermometer. Mercury is a poisonous substance and should not be handled. VHHS no longer has any mercury thermometers.
• Broken glass that has contacted blood must be disposed of in a sharps container.
• The plastic cylinder gaurd on a graduated cylinder is to protect the cylinder from breaking if it should tip over. The cylinder gaurd is not made to slide up and down for measuring.
• A graduated cylinder should be laid down when it is empty - if it is laying down it can't be tipped over.
• Remove glass tubing and funnels from stoppers as soon as your lab is finished. If you do not they will become stuck in the stopper.

Bloodbourne Pathogen Safety

• Wear latex gloves anytime you assist someone who is or has been bleeding or vomiting.
• Clean the entire area (desktop, floor, etc.) with a disinfectant when you are finished caring for the person.
• Remove your latex gloves by pulling them off inside out. Avoid contact with the outside of the gloves.
• All paper towels, tissues, latex gloves and other materials used to clean up blood and other possible infectious materials should be disposed of in the proper biohazardous waste bag.
• Standard Biohazardous waste bags are red with the biohazardous waste symbol on them. If one is not available, use a regular plastic garbage bag and attach a biohazardous waste sticker to the bag.
• Wash your hands thoroughly with a disinfectant when you are finished.

this is the best answer!!!! :')

Answer 5

Some chemicals can harm us if they are not handled carefully. Hazard symbols are used to identify the danger posed by each chemical and what care should be taken.

Hazard symbols and what they meanSymbolMeaning

Corrosive

Corrosive

Concentrated solutions of strong acids and strong alkalis are labelled with the 'corrosive' symbol. Anyone using a corrosive substance should wear gloves and eye protection, such as goggles or a face shield.

Irritant

Irritant

Dilute solutions of acids and alkalis are labelled with the 'irritant' symbol. Anyone using an irritant substance should wear eye protection such as goggles, and they should take care to wash any spills off their skin immediately.

Toxic

Toxic

Very poisonous chemicals are labelled with the 'toxic' symbol. Anyone who uses a toxic chemical needs to take great care. They should wear gloves and eye protection, and they may wear a mask over their mouth and nose, or handle the chemical in a fume cupboard.

Harmful

Harmful

Less poisonous chemicals are labelled with the 'harmful' symbol. Anyone using a harmful substance should wear eye protection such as goggles, and they should take care to wash any spills off their skin immediately.

Highly flammable

Highly flammable

Chemicals that ignite very easily are labelled with the 'highly flammable' symbol. In addition to the normal precautions of wearing eye protection, anyone using a highly flammable substance should take care to keep it away from flames and sparks, and also from oxidising substances.

Oxidising

Oxidising

Oxidising substances do not burn themselves, but they provide oxygen for flammable substances to burn. They are labelled with the 'oxidising' symbol. In addition to the normal precautions of wearing eye protection, anyone using an oxidising substance should take care to keep it away from flammable substances, including clothing.
