LABORATORY SAFETY

GUIDELINES

PREPARE PROPERLY

• Wear a lab apron when working with harmful chemicals.

• Wear safety goggles when working with chemicals or heating substances.

ADULT SUPERVISION

• Never conduct experiments without adult supervision.

• If you are injured notify the teacher immediately.

SPECIAL EQUIPMENT

Be familiar with the location of the following equipment:A. Fire extinguisherB. Fire blanketC. Emergency showerD. Eye-wash station

SPILLS…

Notify your teacher immediately if anything spills.

Spills need to be cleaned up quickly and correctly.

FOOD/DRINKS

Never eat or drink in the lab

CLEAN WORKING AREA

Wash your hands thoroughly after handling chemicals, cultures, plants, or animals.

DANGER!

Pull long hair back.

Roll long sleeves up when working with fire.

ELECTRICAL CORDS

• Be sure that electrical cords are not in a place where someone can trip over them!

• When working with electricity make sure your hands are dry.

CLEAN UP

• Be sure that all laboratory surfaces, equipment, and tools are cleaned after you finish with them

• Dispose properly of all chemicals.

HEAT!

Turn off hot plates and burners when not in use.

Turn off microscopes when not in use.

HEATING SUBSTANCES

• When heating a substance, always point the test tube away from you and other people.

• When heating over a burner (flame), gently move the test tube over the hottest part of the flame.

• Use tongs or hot pads when handling hot equipment. Use a test tube holder when heating substances in a test tube.

BROKEN GLASSWARE

Do not use chipped or broken glassware.

Discard broken glass according to your teacher’s instructions.

ACID……

BURNS

If you burn your skin, run cool water over the affected area.

HORSEPLAY

• “Horseplay” in the lab is not tolerated under ANY circumstances. It can lead to chemical spills, accidental fires, and broken equipment.

• Never throw anything.• No wrestling, punching or shoving in

the lab even if you’re just “playing”. • Those types of behaviors will result in

your removal from the lab and you will earn a zero for that lab. You may also be excluded from future labs due to inappropriate behavior!

WARM- UPWARM- UP

Remember the safety rules we talked about yesterday?

On a sheet of paper (NOT your notebook) answer these questions:

1. How can you use these rules outside of class?

2. Give me some examples of rules from science class that are similar to rules that you follow at home
