It is amazing how careless some people are. They just do not bother to take the proper safety precautions when using certain equipment or doing certain procedures. I think we are going to have to have a refresher course for all staff that works in the labs to make sure that they start behaving more responsibly. They need to use the fume hoods more often to make sure that no dangerous fumes get into the air that we need to breathe, and they need to take the other necessary precautions as well. With a refresher course we will know that at least everyone has been informed of what they are supposed to do.
