1. Kim walks into a laboratory that routinely uses chloroform and notices a broken bottle on the floor in a puddle of liquid and immediately detects a pleasant, sweet odor in the air. What should she do?:

Sweep up the glass and dump it into the trash before hosing the liquid down the floor drain.
Dab some chloroform behind her ears in hopes of impressing the guys in the lab next door.
