Pesticide labels have signal words on them that describe the acute (short-term) toxicity of the formulate pesticide product. The signal word can be either: DANGER, WARNING, or CAUTION. Products with the DANGER signal word are the most toxic and products while the products with the CAUTION signal word are lower in toxicity. The U.S. Environmental Protection Agency requires a signal word to be printed on the front label, in all capital letters, to make for easy classification and clarification for the user.

The U.S. EPA determines the appropriate signal word after completion of studies by the manufacturer on the toxicity of the product. The required studies include oral exposure (eating the product), inhalation exposure (breathing in the product), dermal exposure (spreading the product on the skin), and exposures to the skin and eyes to examine for irritation. The study that shows the highest toxicity is used to determine the signal word.
