Final answer:
When applying pesticides, it is required to leave written notice with the registered company's name, applicator's license number, and the chemical details of the pesticide. This aligns with the EPA's FIFRA regulations to ensure safety and proper identification of pesticides used.
Step-by-step explanation:
The question pertains to the proper procedures an applicator should follow when applying pesticides within, around, or to any structure. It is essential to leave a written notice in a conspicuous location that provides specific information to ensure the safety and compliance with regulations regarding pesticide use. The proper notice should include the registered company's name and the applicator's license number, as well as the technical chemical name and category signal word of the pesticide used. This ensures that individuals are aware of the potential risks associated with the chemicals present and can take necessary precautions.
Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), administered by the Environmental Protection Agency (EPA), all pesticides sold in the U.S. must be registered and their use strictly regulated to minimize harm to humans and the environment. The information left behind should enable the understanding of potential risks and necessary safety measures. This is particularly important in cases where ecologically based control measures are not adequate, and pesticides must be used as a 'last resort'. Using trade names and EPA registration numbers can also help in identifying the exact products used and facilitate any needed follow-up actions, such as dealing with possible exposure or poisoning scenarios.
