Hi there, this question deals with, of course, safety in the laboratory.
00:07
That is the most important thing in any science laboratory is safety.
00:19
So let's look at the options here.
00:21
We want to see which one of these is not a correct procedure.
00:26
So the first one is hands should be washed frequently during the course of an experiment.
00:31
That is always a good one, especially if there's any chance you're getting anything on your hands, you want to wash them frequently.
00:42
That is a great idea.
00:49
So that's a good one.
00:50
Next one says lab coats should not be worn for other uses outside the lab.
00:56
That's also a good one, especially if they haven't been washed.
01:01
Although they make a great halloween costume, you don't know what chemicals have been spilled on them.
01:16
So that is a great one.
01:18
You don't want to wear those lab coats.
01:19
They have a purpose and that is to be worn in the lab to protect the rest of your clothing from chemical spills and splashes...
