Very interesting perspective. You do have some good points to
make, but the issue is not perception with regards to laboratory safety.
I do agree, conditions in the past were much more hazardous than they are
today, but it is our responsibility as instructors to maintain a safe
working environment and make our students aware of safety considerations
both for themselves and their fellows. I do not advocate forcing
unnecessary precaution, but I do stress that an awareness of potential
hazards coupled with good, sound preventive antiseptic and aseptic
technique is important, to health and well-being. Thanks for your
