  1. Laboratory Safety Webinar:Creating a Culture of Safety December 5, 2013 3:30-4:30pm

  2. Session Objectives • To identify relevant information in OSHA Laboratory Standard Appendix A and recommended resources • To identify strategies that encourage a “Culture of Safety” through training and ongoing support

  3. OSHA Laboratory Standard (29 CR 1920.1450)https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10106 • Appendix A provides employers assistance in developing an appropriate Chemical Hygiene Plan https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10107 • Based on the National Research Council’s (NRC) 2011 edition of “Prudent Practices in the Laboratory: Handling and Management of Chemical Hazards” http://www.nap.edu/catalog.php?record_id=12654orwww.nap.edufor additional free resources • Appendix B provides a list of references

  4. What does Appendix A tell us about a culture of safety? Let’s go back to the document introduction https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10107

  5. How do we establish a culture of safety? A. General Principles • Minimize All Chemical Exposures and Risks • Avoid Underestimation of Risk • Adhere to the Hierarchy of Controls • Provide Laboratory Ventilation • Institute a Chemical Hygiene Program • Observe PELs and TLVs

  6. 1. Minimize Exposure & Risks • Perform risk assessments for hazardous chemicals and procedures prior to lab work: • Identify chemicals to be used, amounts required and circumstances of use in the experiment. • Evaluate the hazards posed by the chemicals and the experimental conditions. • Reaction scale-ups pose special risks. • Select appropriate controls to minimize risks.

  7. 1. Minimize Exposure & Risks 5 questions: • What are the hazards? • What is the worst thing that could happen? • What can be done to prevent this from happening? • What can be done to protect from these hazards? • What should be done if something goes wrong?

  8. 2. Avoid Underestimation of Risk • Even for substances of no known significant hazard, exposure should be minimized. • Reference the MSDS/SDS for each chemical. • Before working with chemicals, know your procedure for accidental spill or fire, emergency numbers, and the location of all safety equipment.

  9. 3. Adhere to the Hierarchy of Controls • (most to least effective) • Engineering controls (remove it- fume hoods, barriers, etc.) • Administrative controls (scheduling) • Work practices (designated procedures to minimize hazard) • PPE (safety goggles, gloves, lab coats/aprons)

  10. 4. Provide Laboratory Ventilation • Chemicals should not be evaporated or stored in the fume hood. • Chemical hoods should be maintained, monitored, and routinely tested. • Laboratory air should not recirculated but exhausted directly outdoors.

  11. 5. Institute a Chemical Hygiene Program • “A comprehensive chemical hygiene program is required. It should be designed to minimize exposures, injuries, illnesses and incidents. There should be a regular continuing effort that includes program oversight, safe facilities, chemical hygiene planning, training, emergency preparedness and chemical security. The chemical hygiene program must be reviewed annually and updated as necessary…”

  12. 6. Observe the PELs and TLVs • OSHA’s Permissible Exposure Limits (PELs) must not be exceeded. • The American Conference of Governmental Industrial Hygienists’ Threshold Limit Values (TLVs) should also not be exceeded.

  13. Appendix A also includes… • Responsibilities • The Laboratory Facility • Chemical Hygiene Plan (CHP) • General Procedures for Working with Chemicals • Safety Recommendations—Physical Hazards • Emergency Planning • Emergency Procedures • Laboratory Security

  14. Recommendations • Make a topic of laboratory safety an item on every group meeting agenda. • Periodically review the results of lab inspections with the entire group. • Require that all accidents and incidents, even those that seem minor are reported so that the cause can be identified. • Review new experiment procedures with students and discuss all safety concerns. Consider less hazardous materials and procedures. • Make sure that all safety rules are followed from the instructor to visitors. • Recognize and reward students and staff for attention to safety.
