priate instructions or precautions which should be taken to avoid these hazards. In some cases, there are consequences which 

may occur if instructions or precautions are not followed. Below are the symbols and signal words along with their definitions 

referenced from ANSI Z535.4 - Product Safety Signs and Labels.
