Miss Fogg Cloverdale High School Be safe Work hard Show respect

While doing science experiments, you’ll be expected to follow safety rules. There are risks involved in handling glass, hot objects, and certain chemicals. Knowing what to do in different laboratory situations will help prevent injuries and accidents.

 Always read all directions before beginning an experiment or activity.  Never perform activities that are not assigned by your teacher.  Do not engage in horseplay.  Never work alone or without teacher supervision.  Food is NOT permitted in the classroom  Never eat or drink at the lab stations during an experiment.  Keep lab station clean and tidy at all times.

 "I didn't mean to" and "It wasn't my fault" are two statements that have no place in the lab  If someone is hurt or equipment is broken, these statements cannot undo the harm.

Eyeglasses and sunglasses are not adequate substitutes.

Follow the dress code!!!

 Always wear goggles and aprons when instructed.  Tie back long hair to keep it away from chemicals, flames, or equipment.  Never wear open shoes or sandals on lab days.  Roll up or secure long sleeves or loose clothing and jewelry.  Contact lenses should not be worn on lab days.

 Report all accidents to Miss Fogg  Know the location of emergency equipment.

 Never heat anything unless instructed to do so.  Use the back of your hand to feel for heat.  Use an oven mitt, clamp, or tongs to pick up a container that has been heated. Never heat a liquid in a closed container. When heating, point the mouth of the container away from others. Keep combustible materials away from open flames.

 Handle chemicals carefully.  Never mix chemicals “for the fun of it.”  Never touch, taste, or smell a chemical unless instructed to do so.  When mixing an acid and water follow the “Triple A Rule”  ADD  ACID  ALWAYS  Use and dispose of all chemicals as instructed by your teacher.

 Never use broken or chipped glassware – report to Miss Fogg for glassware disposal.  Never eat or drink from glassware.  Clean all glassware before putting it away.  Never pick up glassware without first checking to see if it is hot.
