Quick Oral Answer
The warning sign shown in the figure is a standard symbol used to indicate that a substance is corrosive and can cause harm if not handled properly. The hand with a drop of liquid falling from it represents the potential for the substance to cause burns or other injuries if it comes into contact with skin or eyes. The test tube with a blue liquid inside represents the substance itself, which in this case is sodium hydroxide (NaOH). Sodium hydroxide is a strong base that can cause severe burns and eye damage if it comes into contact with skin or eyes. Therefore, it is important to display this warning sign on containers that contain sodium hydroxide to alert people of the potential dangers.
