What does the signal word "Caution" imply regarding toxicity?

The signal word "Caution" is commonly used in labeling and safety instructions to indicate a certain level of toxicity associated with a substance. When "Caution" is present, it signifies that the substance poses a slight risk to health, suggesting that it is slightly toxic. This means that exposure could lead to mild health effects but is generally not considered dangerous compared to substances labeled with more severe signal words like "Warning" or "Danger," which indicate moderate or high toxicity respectively.

Thus, the implication of "Caution" aligns with the understanding that users should still practice care and follow safety guidelines but the threat is relatively minimal compared to higher toxicity levels. This context helps to clarify the nature of risk presented by the substance.
