Final answer:
The mandatory information on a pesticide label includes the EPA registration number, signal word, and active ingredients, but does not require NFPA 704 data. The correct option in the final answer is NFPA 704 data, which is not necessary for a pesticide label.
Step-by-step explanation:
When examining a pesticide label, it is important to note the mandatory information that must be displayed. This information includes the EPA registration number, which signifies that the product has been evaluated and registered by the Environmental Protection Agency, according to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The label must also feature a signal word, such as 'Danger', 'Warning', or 'Caution', to indicate the level of toxicity and potential hazards to human health and the environment. Additionally, the active ingredients are required to be listed, detailing the chemicals that act against pests.
Conversely, NFPA 704 data, which refers to the National Fire Protection Association's hazard identification system, is not a mandatory requirement for pesticide labels. The NFPA 704 system is a standard that provides information concerning the health, flammability, and instability risks of chemicals. While this information can be beneficial, it is not a compulsory element of pesticide labeling under the regulations set forth by the United States government.
Therefore, the answer to the question 'Which of the following IS NOT mandatory information found on a pesticide label?' is c) NFPA 704 data. Users need to be aware of the mandatory information to ensure the safe handling and application of pesticides.
