Would you know what to do if one of your students had an accident with a chemical that resulted in contact with the skin? What would you do if a student spilled boiling water on his or her hands? These are the types of potential challenges science teachers face every time they walk into a laboratory with students. Prepare yourself for the worst case scenario by developing a first-aid policy for your science classroom as outlined by the Occupational Safety and Health Administration Regulations (OSHA).
