  2. Science Safety:Daily Learning Goal The student will be able to apply knowledge and understanding of safe laboratory practices and procedures.

  3. WHMIS WHMIS (the Workplace Hazardous Materials Information System) is the law throughout Canada. As applied to high school labs: • There is to be no eating or drinking.

  12. Some of those instructions Re: injury prevention Be aware of other students at desks around yours!

  13. Some of those instructions Re: injury prevention Labs should be done standing up. Stools should be pushed under the benches. If you need to observe a reaction at eye level, crouch down.

  14. Alerts All accidents (fire, spills, broken glass, etc.) must be reported to the teacher immediately.

  15. Alerts Note the location of the: • Three exits. Exit through the science office only if the main exit is blocked by fire. • Fire extinguisher. Located where?

  16. Alerts Note the location of the: • Eye wash station. Open both eyes while the water is running into your eyes.

  17. Alerts Note the location of the: • Broken glass disposal. Do not touch broken glass with your hands, especially if the glass contained chemicals.

  22. More on WHMIS Please take a moment now to review WHMIS symbols and the MSDS. This information is in your textbook. (Where?)

  23. Compressed Gas Other Toxic Effects Biohazardous Infectious Material Combustible (Fire) Oxidizing Material Corrosive Material Immediately Toxic Substance Highly Reactive Material

  24. Household Hazardous Product SystemHHPS

  25. OTHER SAFETY NOTES • Glassware! – handling and assembly! • Test tubes and instruments • Acids! Triple A – “Always Add Acid!” • Hot glass! – Looks like cold glass! • How to use your sense of smell SAFELY • Burns! – what to do! • Magnesium story

  26. DEMO – Bunsen Burner Watch me, then try yourselves in PAIRS Safety glasses! SAFETY FIRST! Fire TRIANGLE – Fuel, oxygen, heat...

  27. Design a POSTER Safety Rules! – WHMIS, MSDS, Lab Practices… No repeats of rules! Rubric handed out! Be creative! Due Monday, March 25 Safety Quiz – Monday, March 25 – based on this PPT (posted to website) and information presented in class (15 T/F QUESTIONS) www.mrsvolkmann.weebly.com
