Golden Rules of Lab Safety

What is not acceptable about these lab investigations? Pause the video and

jot down your answers.

Scenario #1 Cindy broke a test tube. Carefully she picked up pieces with one had and

placed them in her other hand. Then she dumped the glass pieces into the wastebasket.

 Scenario #2 Mike and Ike had a lot of a chemical left from their investigation. They

dumped the chemical in the sink and left the water running in the sink as they left class.

 Scenario #3 Jimmy and Cricket were going to be late to their next class. After rushing to

put away a few materials, they left the rest of the materials on the lab table.
