Safety In the Laboratory
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?
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
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!
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
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.
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
MSDS Sheet SectionsSee 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
When doing science remember…
SAFETY FIRST!!
