3. Mnemonic Devices
3.1. A mnemonic device for safety rules: Safety always comes first After a lab, you clean up Focus on the lab and don’t play around Emergencies should be reported, but not always first Try to help those around you Yelling should be minimized for others benefit Report all cuts and burns Under no circumstance should you not have safety goggles Leave any broken glass mess for Mr. Lajeunesse Extra chemical should not be returned to original container Spills can be cleaned up by students. - Grace Maloney Block 4
