TEKS B.1A Demonstrate safe practices during laboratory and field investigations

Prerequisite Questions What does it mean to be safe? List some unsafe behaviors…

General Expectations •FOLLOW ALL INSTRUCTIONS GIVEN BY THE TEACHER! (most of the answers on the safety quiz involve telling your teacher when a mishap occurs) •NO HORSEPLAY •NEVER EAT OR DRINK WHILE EXPERIMENTING •KEEP YOUR WORK AREA CLEAN AND UNCLUTTERED

Dress Code Wear safety goggles for the entire experiment over your eyes. Wear an apron to protect your clothes Tie back long hair and dangling sleeves. Take off loose and long jewelry. Wear closed toed shoes.

First Aid Report all accidents-big or small to the teacher. Know where the safety shower, eye wash station, and fire blanket/extinguisher are located. Know where the fire exit is located. Know the location of the first aid kit.

Chemical Safety Always point containers of open chemicals (beaker, test tubes, etc.) away from yourself and others. Never touch, taste or smell anything unless instructed by the teacher.
