The task is to identify what is wrong in each of the laboratory safety scenarios depicted in the images. Below are the explanations for each image:
---
Image 1:
-
Description: A person pouring a liquid from a beaker into a container while looking down at the container.
-
What is wrong: The person is not wearing any protective eyewear (goggles). This is dangerous because chemicals can splash and cause eye injuries.
---
Image 2:
-
Description: A person lighting a Bunsen burner with a match while holding the burner in their hand.
-
What is wrong: The person is holding the Bunsen burner while lighting it, which is extremely dangerous. If the burner tips over or the flame spreads, it could cause burns or start a fire.
---
Image 3:
-
Description: A person using a hot plate to heat something while standing too close to the equipment.
-
What is wrong: The person is standing too close to the hot plate, which increases the risk of getting burned if something spills or the hot plate overheats.
---
Image 4:
-
Description: A Bunsen burner placed on top of a stack of books.
-
What is wrong: Placing the Bunsen burner on books is highly unsafe. Books are flammable, and the heat or flame from the burner could ignite them, causing a fire.
---
Image 5:
-
Description: A person smelling a substance directly from a test tube.
-
What is wrong: Smelling substances directly from a test tube is dangerous. Chemicals can be toxic or harmful when inhaled. Instead, one should use the "wafting" technique by gently wafting the vapor toward the nose.
---
Image 6:
-
Description: A group of people gathered around a lab setup, with one person reaching out to touch or adjust something.
-
What is wrong: There are too many people crowded around the lab setup. This creates a hazardous environment where someone might accidentally knock over equipment, spill chemicals, or get injured. Additionally, the person reaching out could disrupt the experiment or cause an accident.

Summary of Answers:
1. Not wearing protective eyewear.
2. Holding the Bunsen burner while lighting it.
3. Standing too close to the hot plate.
4. Placing the Bunsen burner on flammable materials (books).
5. Directly smelling a substance from a test tube.
6. Crowding around the lab setup.
