Text/Lab Manual and Safety
Do not just assume that everything in a textbook or lab manual is correct or safe. Also do not assume information from the Internet is correct or safe. Assure yourself that the materials you teach from are reliable and promote good safety practices. It is your obligation to ensure that the information is correct. If you develop your own material, you have a very special obligation for accuracy and predictability. It would be a good idea to have your material reviewed before using it.
