1. Safety In the Laboratory

2. Wearing Safety Gear You must always wear the following during a lab: –Goggles –Apron Failure to wear these items will result in the removal from the activity with a ZERO on the lab! Mrs. Lukacsko will tell you when it is safe to take the items off. DEMOS: –What will acid do to your eye? –Why are contacts dangerous in the lab?

3. Locating Safety Equipment You need to be able to locate the following pieces of safety equipment in case of an emergency: –Fire Extinguisher –Eye Wash Station –Gas/Power Shut Off Button –Broken Glassware Box –MSDS Clipboard

4. Safety Contract You and a parent/guardian MUST sign and date the safety contract and return it to Mrs. Lukacsko BEFORE you can do any laboratory activities. Science is fun, but remember – Safety First!

5. NFPA Label – National Fire Protection Association

6. NFPA, cont. Each of the three colored areas in the NFPA fire diamond has a box in which the degree of hazard can be written. The degree of hazard is given by these numbers: NumberDegree of Hazard 4 EXTREME 3 SERIOUS 2 MODERATE 1 SLIGHT 0 MINIMAL

8. The “Special” Category –Materials which are unusually reactive with water are denoted with a "W" with a slash through it. The number in the yellow box will then indicate the degree of reactivity. –Materials which are capable of increasing the intensity of a fire by supplying fuel during fire situations will be labeled with the legend "OX" in this section of the diamond.

9. MSDS Material Safety Data Sheet Before you handle a chemical, you should read its MSDS – every chemical is unique and needs to be handled differently! Has multiple sections that contain information Also has an NFPA on it! Important Sections: –Emergency First Aid Procedures, Fire Hazard, Spill Procedures, Reactivity Data

10. MSDS Sheet Sections See Handout/Overhead for Examples Section 1 –Name of Chemical –NFPA Label Info. Section 2 –Any Specific Hazard Section 3 –Appearance & Odor –Melting/Boiling Points Section 4 –Type of Fire extinguisher to use Section 5 –Amount of Chemical you can safely be exposed to –First Aid Procedures Section 6 –Is it stable or unstable at room temperature? Section 7 –How to clean up a spill Sections 8-end –Special Information

11. When doing science remember… SAFETY FIRST!!
