Which scenario shows responsible behavior with regard to lab safety? 1. nathan threw out his lab safety instructional manual after reading it. 2. jessica and elizabeth ate their lunch and evening snacks in the lab area. 3. haley poured multiple tubes of poisonous chemicals down the lab sink. 4. adam immediately cleaned up the fluids he had spilled in the lab area. (earth science)

The answer would be:

Adam immediately cleaned up the fluid he had spilled in the lab area (option 4)

This is why:

If there is a spill in the lab, you should clean it, but also do not forget to also follow the safety precautions, especially with chemical spills. Spills can cause injury, like someone might slip on it or you might slip on it. It will also prevent contamination of other chemicals. Some chemicals can become volatile when mixed with other substances.

As for the other options. You should keep the manual even after reading as reference. NEVER eat in the lab. You may never know what you might ingest as well. All chemicals have guidelines when it comes to disposal. Never throw them all down the sink.
