I teach a chemical engineering unit ops lab. Most of the experiments are done with water when possible, but some have hazardous chemicals as well. I have a laboratory safety manual that I have written for the course. I go over it with the students the first day of class and give them copies (they have access to it electronically as well and a copy in the lab). The second week of classes, they take a multiple choice quiz over the safety manual and have to get 8/10 correct before they are allowed in lab. If they score lower, the student and I go over what was missed, any questions they have, and the student retaks the test until they get an acceptable score. I also go over in class any questions that were missed by anyone on the quiz (without naming names, of course). I then keep copies of these tests for my records.

Also, the last page of the safety manual is a signature sheet stating that they agree to conduct themselves in a safe manner and have read and understood (asked any questions they needed, etc) the manual. I have them sign it and turn it in before they go to the first lab. This gives them around 1-2 weeks to look over it and chances to go over missed items on the quiz. I also keep this signature sheet for my records.
My TAs also have the right to ask a student to leave the lab if they are acting in an unsafe manner and not correcting their behavior when the TA asks them. The then have to come meet with me before they can go back in the lab. Thankfully, this has never happened.

We also go over safety as part of the lecture of the course including any hazardous chemicals they may use in upcoming labs, gas cylinder safety, etc. We also use a lot of CSB videos. At the end of the course, they have another safety quiz that covers safety taught over the entire course. The one concerning question I find they miss too much on this test is a schematic of the lab room where I ask them to indicate the location of the safety shower, eye wash, and fire extinguisher. So, I now emphasize to them even more the need to know these locations. So far, the safety aspect of the course has been very well received by the students. It is always a positive comment for the course on evaluations.
