General Lab Safety

General Lab Safety

Captions are on! Click CC at bottom right to turn off. Follow the amoebas on Twitter (@AmoebaSisters) and Facebook. Ah, labs. We LOVE labs. They’re the best part of science: the whole
doing part. And since you’re probably going to be doing
some amazing science labs this year, we thought we’d outline a few major points of general
lab safety. Because safety is a big deal. And while this is certainly NOT all the points
of safety—always read through the safety guidelines specific to the lab you’re doing—these
are some major, general safety rules that apply for many types of labs. First let’s talk about shoes. And hair. We have neither of those. But if you do— long hair needs to be pulled
back. You should wear closed toed shoes because
you don’t want to be pouring something toxic on your feet or walking on broken glass. Speaking of broken glass— bags and stuff
in the aisles in lab rooms do not help. You want to clear a path and not have your
belongings out where someone could trip over them. And no horseplay. To protect your eyes, wear goggles. And when we say “wear goggles” we all
know that on your forehead doesn’t count. If you do feel as though something has gotten
in your eyes, you will want to use the eyewash station, which will require you to hold your
eyes open under the running water. If your lab involves working with specimens
or chemicals, you will likely be advised to wear gloves. Gloves are important. Yes, sometimes they make your hands feel clammy. But you know what’s worse? Chemicals that can irritate or burn your skin. If you have an allergy to latex, you should
make sure that the gloves you are using are latex free—ask your instructor. In fact, if you have any allergies, you should
let your instructor know. When you finish a lab, even if you wore gloves,
it’s a good idea to wash your hands after time in the lab. Some labs may require you to wear an apron
to protect your clothes. Depending on what type of course you are in
and the type of labs you are doing, you also may have a safety shower which will dump a
very large amount of water on you if you get some type of hazardous chemical on you. If you accidentally break glassware, don’t
pick it up. It could cut you. A broom and a dustpan should be used to clean
it up, and there should be a place designated for broken glass. Not the regular trash where it would just
break through the trash liner. If you see glassware that is chipped already,
don’t use it and tell your instructor. Never drink or eat anything in the lab. That includes chemicals. Don’t taste or smell chemicals. Read labels. Don’t ever pour chemicals that you may be
using back into the bottle that they came from. As soon as you finish pouring chemicals out
of a container, the container should be immediately closed. When you’re done with a chemical, you want
to make sure you properly dispose of it. Many chemicals can’t just be put down the
drain. In fact, some solid items that you use in
your labs also cannot be thrown away in the regular trash and have to be disposed of as
hazardous waste. Always check with your instructor. In some labs, you may have a special ventilation
system, also known as a “fume hood.” This is used when dealing with volatile substances,
which is a fancy way of describing a substance that easily vaporizes. Some of your labs may require the fume hood
because some of these volatile substances may be harmful if you inhale them. When you’re heating things up, like this
test tube in a hot water bath, don’t have the test tube pointed towards you. Use tongs or heat protective gloves to handle
the test tube that you may be heating. Also, electricity and water are not a good
mix. So when you’re doing your super awesome
microscope lab, you want to keep the water away from the electrical cord. And speaking of microscopes, we could have
an entire video on just working with the microscope. But for now, we’ll make sure to mention
carrying it with two hands. One hand underneath the base and the other
holding the microscope arm. If you are using any special science equipment,
it is important to know how to carefully carry it. If you are in a lab that has an open flame,
obviously be aware of the flame. Review with your instructor how to operate
the valve that controls the gas fueling the flame. Review with your instructor how to properly
heat the various glassware that will be suspended over the flame. Every time you are in the lab with an open
flame, you must keep all materials that may be flammable away from the area near the flame. Depending on the types of labs you are doing,
your lab room may also have a fire extinguisher and/or a fire blanket in the room. Finally, the MSDS. It stands for material safety data sheet. It’s available for pretty much every substance
you use in your lab. You should refer to it, because it will give
you all kinds of safety information on a substance including how to safely handle it, what to
do if there is an accident with it, how to safely dispose of it, and more. Ok. So, yeah, that was a lot. And there are so many more safety guidelines
that may be specific to the lab that you are going to do so you always want to go through
specific guidelines in advance of your lab. We’re going to put some items up here so
you can pause this video and determine where those items are if they’re relevant to your
lab room. Remember, don’t be intimidated—just respect
safety rules and guidelines because if you’re following them, hands on science is simply
awesome. In addition to the hands-on part of science,
you can always check out our science comic video clips that may be helpful on a variety
of science topics you might cover this year. Well…that’s it for the Amoeba Sisters
and we remind you to stay curious.

  1. Tysm!
    I’m taking a test tomorrow on lab safety and didn’t take enough notes.
    So this REALLY helped 🙂

  2. ew

  3. i´m officially in love with your animations! i was here for my homework but I ended up rewatching it like 8 times 😀

  4. Tuesday, 10:27AM: Student's log, I didn't study the night before, today is the day of the first Semester exam, I am a senior, so this grade may determine if I will graduate this year. This is one of many review videos I'm speed viewing hours before the exam, to remember 4 months worth of chemistry. Student log – R

  5. Once I was doing a baking soda and vineager experiment and it sprayed in my eye. I wasn't hurt, but I took the opportunity to reference the movie "Bolt" and cried out "SPICY EYES!!!!!". I was okay, I just made the joke. It was the fizzinator experiment where you have a balloon over the bottle and the balloon had a leak, so that's how it shot in my eye. Tip: SAFETY GOGGLES.

  6. كيف أتعلم اللغه الإنجليزية علشان افهم المحاضرات ذي ارائعه الي يعرف أتمنى منه يفيدني

  7. Lab dissecting a frog 🐸 I Barely survived I like almost threw up 🤮 The smell was everything awful , just awful ugh 😑 Teacher gave me full credit for trying and not throwing up 😂

  8. got my Bio exam so starting over from the beginning and watching almost all of the videos lol …. pray for me :/

  9. Great Animation. read also this article about laboratory safety from

  10. We like to pin a comment at the top of our videos for clarifications—you may see the term "SDS" as the Material Safety Data Sheet (MSDS) has been replaced with the term Safety Data Sheet (SDS). We have a card in the video that pops up when this is mentioned. This also is reflected on our accompanying handout: (under 'safety').
