Investigations in the Lab Think before you act Get permission before you begin Know location of safety
equipment (i.e. eyewash station, fire extinguisher)
Find and follow all safety symbols
Never eat/drink or apply make-up in lab
Report all accidents/injuries immediately
Wash hands Put all material away as directed
