What are technicians required to keep on file regarding pesticides?

Technicians are required to keep on file all licenses and certifications for themselves and their company to ensure compliance with legal and regulatory standards in pesticide application. Having this documentation readily available demonstrates that the technicians are properly trained and authorized to handle pesticides, which is crucial for ensuring the safety of both the environment and public health. Keeping licenses and certifications on file also provides a way to verify that the technicians are up-to-date with current practices and regulations mandated by various governmental agencies. This helps maintain industry standards and mitigates the risk of using outdated or unapproved methods.

The other choices, while relevant to different operational aspects of pest management, do not specifically pertain to the core requirement of maintaining documentation for legal compliance in pesticide handling.
