Safety in the Science Lab

SAFETY DRILLS Now seems like a good time to discuss procedures… Fire Drill – out the door to the right, go to parking lot past bus lane. Stand together. Tornado Drill – interior hall walls outside classroom. Lock Down – lights, windows, on floor. ALL DRILLS – QUIET.

SAFETY DRILLS Fire in lab Chemicals Know location of each. Fire extinguisher Fire blanket Chemicals Eye wash (15 minutes) Emergency shower Know location of each.

SAFETY DEMO Why we wear goggles when working with some chemicals.

KNOW YOUR CHEMICALS Important to know in the workplace! Labels – Give Basic Info and Warnings Materials Safety Data Sheets (MSDS) – More detailed Health hazards Ingredients Precautions Transportation Spill & Disposal info Reactivity Combustibility Physical properties Important to know in the workplace!

LAB SAFETY CONTRACTS REQUIRED. Parents and students must sign. Required before lab work can be done. Alternate assignment from book for those who don’t return contracts. Due back to us Tuesday signed by you and your parent.

ACTIVITY: SAFETY SCENARIOS Working in groups of two, discuss the scenario presented on your card and decide: 1. What rule applies. 2. How you could PREVENT the problem from occurring? 3. Develop a plan to handle the problem as both a student and a teacher. You MUST refer to your Lab Safety Contract for guidance! Be prepared to share!

PERFORMING A LAB Plan ahead - read the lab twice. Gather and organize equipment. Follow the procedure step by step. Record ALL observations and use the proper units of measurement. Clean up, wash hands, put equipment back where it came from. Answer the questions that go with the lab in complete sentences with no misspellings.

REMAINDER OF CLASS… Work on your Earth Systems Project – poster or brochure. Due Thursday. Safety Contract due by Friday.
