When I found a student not wearing safety goggles or glasses, I would take the person to that book and open it to those [pre-marked] pages without saying a word. I rarely if ever had such a person forget to wear that PPE again.
I always figured those pictures were not only worth the proverbial 1000 words, but worth the price of the book.

I know you guys love this kind of stuff! So send me your favorite gory images. I have a collection of my own Iím going to send to her but itís good to be a hunter gatherer. If I get a good selection, Iíll put it into a powerpoint (or similar) and post it on our website.
I am the instructor for BIT161A Ė Genetics and Biotechnology Lab. This is a 6 unit molecular biology lab that is held in the Winter Quarter and the labs are on average 6 hours long.
Recently we increased class enrollment from 14 to 24 and because of this, it is harder to monitor the students to ensure that they use safe practices. I have changed the lab so that we use few harmful chemicals! . Now, the biggest hazards are ethidium bromide which we use often, open flames for sterilization, and melting agarose gels in the microwave. We go through lab safety for 30-45 min on first day of class and for the first few weeks the students are diligent. However after that things get a little sloppy and I constantly have to remind people to be careful, to think and to be watchful etc.
I was wondering if you had a few slides I could use to show the consequences of not being attentive in the lab. Accidents caused by seemingly silly mistakes. Wonderfully gory images will be especially effective I think.
Please let me know your thoughts.
