  2. 2. LABSAFETY SAFTEYOF STUDENTS
  3. 3. LABSAFETY SAFTEYOF STUDENTS The Biochemistry laboratory can be a place of discovery and learning. It can be a place of danger if proper common-sense precautions aren't taken
  4. 4. GOOD LABORATORY CONDUCT Conduct yourself in a responsible manner at all times in the laboratory
  5. 5. GOOD LABORATORY CONDUCT Follow all instructions Do not play in the laboratory Do not use any laboratory equipment until you are told to do so Do not perform any laboratory procedure until you are told to do so
