  • Thank you for allowing me to speak to you today. I would like to share with tyou the progress we have make at Hendrix College in integrating safety throughout our curriculum. I feel that
  • The students were already being hit with safety information from multiple directions.
  • Hendrix College Undergraduate Lab Safety

    1. 1. Safety Here, Safety There, Safety, Safety Everywhere<br />Using Educator and other tools to integrate safety into the curriculum <br />Shelly Bradley<br />Hendrix College<br />NRCC – CHO<br />Authorized OSHA Trainer<br />
    2. 2. Hendrix College 2010<br />2<br />Hendrix College Safety Program<br />Safety training – Basic rules<br />Lab handouts<br />Faculty reinforcement of rules<br />Labeling<br />
    3. 3. Hendrix College 2010<br />3<br />ACS Safety Guidelines<br />“Discussion of the hazards involved in specific experiments…”<br />“progress…develop a high degree of safety awareness…”<br />“…build a health and safety information knowledge base.”<br />“…safety procedures and processes…experience in handling hazardous materials safely.”<br />
    4. 4. Hendrix College 2010<br />4<br />Safety Lecture<br />Beginning of each semester<br />Basic 1st and 2nd year<br />Advanced for upper level<br />Information Progresses each semester<br />Basic Rules<br />General Health and Safety Knowledge – Builds on previous semester/course<br />Increasingly more interactive<br />
    5. 5. Hendrix College 2010<br />5<br />Lab Handouts / Prelab Lecture<br />Hazard information in body of experiment<br />Faculty reinforced during prelab<br />Consistent throughout curriculum<br />CAUTION – Digesting materials in HNO3 will generate the brown, noxious gas, NO2(g). When the sample is destroyed (solution is transparent, no visible material), remove the beaker from the heat using tongs and remove the watch glass, keeping the solution in the hood. This will allow the NO2 to escape into the hood and should leave a transparent, colorless solution, usually 10-15 min is sufficient.<br />
    6. 6. Hendrix College 2010<br />6<br />Web-based Course Management Tools<br />Educator<br />Blackboard<br />WebCT<br />
    7. 7. Hendrix College 2010<br />7<br />Prelab Safety Quiz<br />Initiated Fall 2009 – Non-mandatory<br />Increasing Participation<br />Positive student feedback<br />
    8. 8. Hendrix College 2010<br />8<br />Laboratory Environment<br />Warning labels on hazardous chemicals<br />Secondary containers<br />Faculty reinforcement<br />PPE enforcement departmentally<br />
    9. 9. Hendrix College 2010<br />9<br />Integration of Disposal Procedures<br />Where possible disposal integrated into procedure<br />Elementary neutralization performed by students in lab<br />
    10. 10. Hendrix College 2010<br />10<br />Green Chemistry Emphasized<br />Organic Lab<br />Green techniques noted<br />Less green alternatives discussed<br />Volume reduction<br />Let students know there is a choice<br />In process – throughout curriculum<br />
    11. 11. Hendrix College 2010<br />11<br />Upper-Level Laboratory<br />Culminating experience for majors<br />Independent Research Initiative (IRI)<br />Put in to practice all that they’ve learned<br />
    12. 12. Hendrix College 2010<br />12<br />IRI Safety Requirements<br />Obtain and evaluate MSDS’s<br />Determine hazards<br />Discuss risks with CHO<br />Outline proper procedure to minimize risks<br />Evaluate waste stream<br />Determine proper disposal methods<br />
    13. 13. Hendrix College 2010<br />13<br />ACS Guidelines<br />How Did We Do?<br />
    14. 14. Hendrix College 2010<br />14<br />ACS Guidelines Regarding Safety<br />Hazard Identification<br />Minimize Exposure / Reduce Risk<br />Hazard and Risk Information<br />Safety Procedures and Processes<br />
    15. 15. Hendrix College 2010<br />15<br />Hazard Identification<br />Progressive Safety Lecture<br />Laboratory Handouts<br />Safety Quizzes<br />Prelab Lecture<br />Hazard Labels<br />Faculty / Staff Reinforcement<br />
    16. 16. Hendrix College 2010<br />16<br />Minimize Exposure / Reduce Risk<br />Green chemical choices and reduced volumes discussed with students<br />Upper-level students responsible for risk assessment<br />Intentional about teaching why instead of just what<br />
    17. 17. Hendrix College 2010<br />17<br />Hazard and Risk Information<br />Sources referred to in Progressive Safety Lectures<br />Safety library easily accessible<br />MSDS’s prominently displayed<br />MSDS exercise<br />
    18. 18. Hendrix College 2010<br />18<br />Safety Procedures and Processes<br />Faculty and staff reinforcement<br />Written SOP for specific hazardous operations – student signature required<br />Accident reviews<br />Involve students in process<br />
    19. 19. Hendrix College 2010<br />19<br />How Can We Do Better?<br />Ideas to engage students more effectively<br />Teaching Chemistry Lab Safety Through Comics<br />Di Raddo, P. J. Chem. Educ. 2006, 83, 571-573.<br />A Lab Safety “Scavenger Hunt”<br />Helser, T. L. J. Chem. Educ.1999, 76, 68.<br />A Laboratory Safety Trivia Game<br />Miller, G. J., Heidman, S. A., Greenbowe, T. J. J. Chem. Educ.2000, 77, 1185-1187.<br />Expand safety quizzes to have knowledge base info on weeks with no hazards<br />
    20. 20. Hendrix College 2010<br />20<br />Value of Presenting at ACS<br />Forces focus on safety <br />Find new resources<br />More clear about objectives and solutions<br />
