The C RC Handbook of Laboratory Safety used to have some [color] pictures of chemi cal splashes to the face.  When I found a student not wearing safety go ggles 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 proverb ial 1000 words, but worth the price of the book.

I know you guys lo ve this kind of stuff!  So send me your favorite gory images.  I h ave a collection of my own I’m going to send to her but it’s goo d to be a hunter gatherer.  If I get a good selection, I’ll put i t into a powerpoint (or similar) and post it on our website.

Dear Debbie

I am the instructor for BIT161A – 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, i t 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 bigges t hazards are ethidium bromide which we use often, open flames for steriliza tion, and melting agarose gels in the microwave. We go through lab safety fo r 30-45 min on first day of class and for the first few weeks the students a re 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 seeming ly silly mistakes. Wonderfully gory images will be especially effective I th ink.

Please let me know your thoughts.
Many thanks!
