Lab Safety Scenario I Below are descriptions of a scenario. Read each scenario and use your own paper to describe what each student should do. Scenario 1: Tamika is working in the lab with several chemicals that are in different test tubes. She is wondering what would happen if she mixes some of these chemicals together.
