Look up examples of different warning labels for things such as food and small appliances. Observe features that stand out about
these warnings (colors, shape, pictures, information, and so on). After looking at a few and seeing how they identify dangers or warn against potential hazards, develop your own safety warnings for a product that you use.
I have developed a product called a "Plant Shrinker" this Plant Shrinker is a powdery substance and is dangerous to digest. I would put a triangle or a diamond shape to indicate danger as it is used that way and we persive it as dangerous. It would contain the following words, "Do not consume, do not let this children, very posionous to consume"
Or if your looking for a product that already exists you could use an air freshener it is dangerous to consume
Side note, sorry if i got it wrong i tried my best... :]
Metaphors and similes are used to add depth and meaning to the poem, so it looks normal on the surface but when you re-read it you uncover a deeper meaning :)
