  1. Science Safety in Texas Public Schools developed by Charles A. Dana Center The University of Texas at Austin

  2. “The accident rate in schools is 10–50 times that of the chemical industry”. NSTA, Guide to School Facilities, 1999

  3. School Chemistry Labs—scene of some frightening accidents—expose lack of safety oversight “In a blinding flash, the routine high school chemistry experiment turned to chaos. An alcohol-fueled fireball shot into the classroom, searing the skin of three junior honor students in the front row.” Tammy Webber, Associated Press, 2002

  4. If an accident occurs in a laboratory • How should you respond if a student is injured? • Who notifies the principal? • Who alerts the school nurse? • Do you include custodial staff? • Who notifies the parents? • Who supervises the other students? • What happens if you are injured?

  5. After the accident is over • Were the safety procedures reviewed? • Did you have the safety equipment to respond appropriately? • Did you have proper first-aid training to respond appropriately? • Were accident reports completed and filed? • Were steps taken to prevent similar accidents?

  6. Emergency Response System • Establish an emergency response team • Who should serve on the team? • What are the team’s responsibilities?

  7. Science Facility and Safety Equipment Checklist

  8. Place a (√ )in the box if the item is appropriate for your grade level. Place an (x) in the box if the item is not appropriate for your grade level.

  9. • How could the teacher respond? • What safety equipment was needed? • What were the safety measures before the accident? • What should happen after the accident? • Could the accident have been prevented? • Could you respond appropriately if this happened in your room?

  10. Whats-Sa-Matta Laboratory Identify the safety violations in this laboratory setting.

  11. Science Facilities Standards What are safe science facilities? What tools are available to plan and design good facilities?

  13. Hazard Communications ActRequirements in the Law

  14. Comprehensive HAZCOM Program • Informing employees of workplace hazards • Labeling chemical containers • Reading and understanding MSDS • Training for employees

  15. Reading and Understanding Chemical Labels

  16. Primary Container Label • Name of material—solution concentration • Name of components and mixture concentrations • Appropriate warning signage • Potential hazards • Immediate first aid measures

  17. Temporary Container Labels • Name of chemical • Appropriate hazard warnings

  18. Hazard Warning Chemical Abstract Number Identity of Chemical Hazard Class & Packing Number Personal Protection Information Formula Weight Specifications First Aid Manufacturer or Distributor 24-Hour Number Date Received Hazard Rating

  19. Material Safety Data Sheets Interpreting and Understanding Information on a MSDS

  20. MSDS must: • accompany chemicals • conform to OSHA standards • be maintained by school • be written or electronic copies • replaced within 30 days • be readily available on request The school district shall not permit use of chemical if it does not have an MSDS.

  32. National Fire Protection Association (NFPA)Hazard Rating Diamond

  33. Special Hazard Hazard Rating Severe Serious Dangerous Minor 0 Slight Flammability Hazard Health Hazard 3 1 0 Reactivity Hazard NFPA Diamond OX

  34. Serious Flammability Hazard Rating 3 1 0 3 OX Flammability Rating “3” • rapidly vaporizes at normal temperature and pressure • rapidly disperses into air • burns readily NFPA Flammability Rating Includes: • very flammable gases • extremely volatile liquids • dust that readily burns • dust that explodes in air

  35. NFPA Health Rating 3 1 0 0 OX Slight Health Hazard Rating Health Rating “0”• exposure under fire conditions offer no hazard beyond that of combustible material

  36. 3 1 0 1 OX Minor Reactivity Hazard Rating NFPA Reactivity Rating • Reactivity Rating “1”• materials must be preheated before ignition can occur• includes most ordinary combustible materials

  37. 3 1 0 OX OX Special Hazard Rating NFPA Special Rating Special Hazard Rating “OX” • materials, on exposure under fire conditions, would offer no hazard beyond that of combustible material

  38. What does this NFPA Diamond mean? 3 4 2 W
