If you are in a school like I was in you, you know that you are not being provided with the lab safety training that is required. I did some research to find something and I came across the Flinn Online Laboratory Safety Course. There are two courses: one for middle school and one for high school. I took both of them (even though there is a lot of overlap) and learned so much!
You might be thinking, "I'm not a Chemistry teacher so this doesn't really apply to me!" I have found that non-chemistry teachers almost need this more because they have less experience with chemicals and don't always deal with them safely when they do use them.
I'm sure there are no school schools who have perfect lab safety procedures and everyone can learn something from this course. I also think it's a good refresher for teachers. I don't recall being taught lab safety techniques when I was in college (either in my science class or my science methods classes). Hopefully things have changed, but in case they haven't this is a must watch for all science teacher.
Comment below with what training you have had on lab safety. I'm interested to hear what happen in other schools.
