Which of the following is NOT a type of hazard statement?

The correct choice is the statement that qualifies as "May be harmful if swallowed." This indicates a potential risk but does not communicate a definitive health hazard like the other statements. Hazard statements are designed to clearly inform individuals about the specific dangers associated with a chemical or substance, typically with a strong assertion of risk.

In contrast, the other options—such as "Fatal if swallowed," "Toxic if inhaled," and "Harmful if swallowed"—represent clear and definitive health hazards. These statements communicate the severity and nature of the risk involved, aligning with the regulatory requirements for effective communication of hazards as outlined in the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals. Hazard statements are intended to provide specific and direct information about the potential harm that could result from exposure to a substance, making the other options valid examples of hazard statements.
