The first is a standard warning symbol, telling you to read the warnings.
The middle looks to imply that it's harmful to aquatic life; so no flushing, (upside-down fish and a piece of coral)
Third one seems to be dosage frequency, but saying a symbol isn't available. (QHS = taken every night)
At least make sure the thing you post is correct for something like this, as it can be important.
The first one (exclamation mark) means it is a irritant and the second one means it is hazardous to the environment (not just aquatic)
Easy there, tiger. 1/3 incorrect.
I wasn't going to explain all of the health effects, aside from an irritant, that the "!" could indicate, especially when the general rule of thumb is to go over the SDS when you see the symbol. The second symbol is definitely for indicating a hazard to aquatic life.
The "G" in the third was confused with a "Q", given the printer resolution. I wasn't sure, so I used more relative wording for saying what it looked like on my screen.
