Lab Techniques & Safety: Crash Course Chemistry #21






Hank takes a break from the desk to bring you to the lab in order to demonstrate some important points about the practical side of chemistry – experimentation in the laboratory. You’ll learn what to wear in the lab, how to dispose of chemicals safely, how to avoid the most common accidents, how to pour solutions properly, what the HazMat diamond means, what an MSDS is, and how to use a fume hood. And as a reward for sticking with him through this maybe less-than-thrilling lecture, you’ll see Hank subject himself to an exciting piece of safety apparatus.

  1. Watching this while being sad because in my school we have amazing biology, physics and chemistry labs,but they are just there.All preference is given to theory.We just copy down experiments in our practical manual without actually doing them in the summer holidays

  2. I accidentally poured a bit of HCl on my hand in 7th grade. Luckily it was extremely diluted and all I felt was a little tingling burn like an ant bite and then I washed it off

  3. I remember watching this a few years back and now as a chemistry major I still go back to this video every now and then to tell people about the broken pipette/rod type of injury. Thank you so much for making this. 🙂
    Don't know if anyone is reading this, but here's another tip- never dilute concentrated aqueous acid by simply adding water to it! Instead, add water to your beaker (or whatever type of equipment you're using) first and THEN pipette the acid into it. Otherwise, the first few droplets of water might react and heat up very quickly and end up splashing and causing burns. Be safe and stay curious!

  4. Super video, but you're going to want to hold that pipette much nearer the top before putting it in the pi-pump or it'll break and go through your hand. Wish I had a nickel for every student who cut themselves by doing it the wrong way almost immediately after being shown.

  5. Hey there internet,
    My chem teacher created chlorine as a by product of some experiment and I took it like a fume hood. My nose bled and I was sick for 2 days. Yay!!

  6. One of the first things I noticed, was the restraint on the cylinder tanks… Each tank should be restrained individually. Just my safety professional opinion …. make your safety video, assuring all items in the background meet safety regulations! 🙂
