What information must service container labels include?

The information that must be included on service container labels is crucial for ensuring safety and compliance with regulations. The correct answer outlines essential elements: the name of the pesticide, the EPA registration number, the active ingredient, the signal word, and the firm information.

Including the name of the pesticide allows users to identify the specific product they are working with. The EPA registration number is vital because it confirms that the pesticide has been evaluated and approved for use by the Environmental Protection Agency, thus ensuring it meets safety and efficacy standards.

The mention of active ingredients is critical for understanding how the pesticide functions and for identifying any potential hazards associated with its use. The signal word, which generally corresponds to the level of toxicity (for example, "Caution," "Warning," or "Danger"), provides an immediate indication of the potential risk involved when handling that specific pesticide.

Lastly, firm information is included for accountability and traceability purposes. Should any incident arise regarding the pesticide, having the manufacturer's information readily available is important for follow-up and resolution.

Overall, the combination of these components on service container labels ensures that the users have the necessary information to handle pesticides safely and in accordance with regulatory standards.
