What does the EPA signal word "Warning" indicate?

• A. Low toxicity
• B. Moderate level of toxicity
• C. High toxicity
• D. Severe toxicity

Answer: (B)

The signal word "Warning" used by the EPA indicates a moderate level of toxicity for a chemical or hazardous material. This signal word is part of a labeling system that helps communicate the potential hazards associated with chemical substances. In this context, "Warning" suggests that the chemical can cause harm if not handled properly, but its toxicity is not as severe as those substances that would carry the signal word "Danger," which denotes a higher level of toxicity.

The use of "Warning" serves to inform users that they should exercise caution and follow safety protocols, as exposure could lead to adverse health effects. This level of alertness is crucial for ensuring safety in environments where various chemicals are used or stored, and enables individuals to take the necessary precautions.
