Chemistry Lab Safety Rules

Chemistry Lab Safety Rules

We are beginning a new unit of study with chemistry. Studying chemistry means using lab equipment and chemicals that are potentially harmful if misused. It is very important that lab rules are followed at all times.

General Guidelines:

1. Read and follow directions.

2. Never perform unauthorized experiments.

3. When entering the room, do not touch any equipment, chemicals, or other materials until told to do so by your teacher.

4. Never fool around.

5. Stay in your assigned lab area.

6. No food or drinks in the lab.

Appropriate Dress:

1. Tie back long hair.

2. No dangling sleeves or bracelets.

3. WEAR SAFETY GOGGLES AT ALL TIMES.

Safety with Chemicals:

1. Never taste or sniff chemicals.

2. Transport chemicals carefully in the lab.

3. Dispose of chemicals properly.

4. Report spills immediately.

5. Leave the lab area neat. Clean and rinse lab equipment if instructed to.

Bunsen Burners and Hot Plates:

1. Keep clothing and body parts away from flames and hot plates.

2. No reaching around or over flames or hot plates.

3. Turn burners and hot plates off when not in use.

4. Report any unlit burners or gas smells to the teacher immediately.

In case of an accident:

1. Report all accidents, spills, and broken lab equipment right away!

2. Never handle broken glass or attempt to clean up spills on your own.

3. Report wet floors to the teacher immediately.

4. If chemicals get on your skin or in your eyes, rinse with lots of running water and report the accident immediately.

5. Be aware of the location of the eye wash station, fire extinguisher, and fire blanket.

Lab Safety Agreement:

I will take responsibility for my own behavior and for my achievement in this class. I will follow the teacher’s instructions, protect my body during experiments, and act responsibly. I understand that I must demonstrate appropriate behavior at all times to be allowed to participate. I am aware that if I do not abide by the above rules I not only risk putting myself in danger of getting hurt, but others too. I understand that breaking any rule means removal from the lab exercise and other disciplinary actions.

Name _________________________________

Centripetal Force and Fluid Pressure

1. _______________________________ is a false force that makes you feel as if you are being pulled out of circular motion, opposite to centripetal force.

2. Centripetal forces always act toward _________________________________________.

3. If centripetal force is removed, an object will continue traveling ______________________________________ perpendicular (tangent) to the center of the circle.

4. The Moon travels around the Earth because ___________________ from the Earth pulls the Moon out of the straight line it wants to travel and into a circular orbit.

5. A _________________ is a material that can flow and take the shape of its container.

6. As you travel up the side of a mountain gaining altitude, what happens to air pressure?

7. As you descend into the ocean, what happens to the fluid pressure the deeper you get?

8. If a fluid is CONFINED in a container and pressure is applied to the container, what can you say about the pressure?

9. What type of moving air has the lowest pressure?

10. Slow moving air under airplane wings creates an area of _______________ pressure that produces lift and pushes an airplane off the ground.
