QAL Laws & Regulation Practice Exam

When dealing with a pesticide that is not an organophosphate, what should be done if there is an inconsistency between the regulation-specified REI and the labeling-specified REI?

1. Use the longer interval

2. Use the shorter interval

3. Ignore the label and rely on state law

4. Consult with a pesticide safety officer

The correct answer is: Use the longer interval

When encountering a discrepancy between the regulation-specified Restricted Entry Interval (REI) and the labeling-specified REI for a pesticide that is not an organophosphate, using the longer interval is the appropriate action. This approach prioritizes safety and compliance with applicable laws, ensuring that workers are protected from potential exposure to the pesticide. The justification for selecting the longer REI stems from the fundamental principle in pesticide regulation: when there is a conflict between regulatory requirements and label instructions, following the more conservative or protective measure is essential. The longer REI provides an additional safeguard, reducing the risk of harm to workers handling or entering treated areas. While there are other options available, such as relying on state law or consulting a pesticide safety officer, they do not directly address the immediate need for compliance with the REI, which is critical for worker safety. Ignoring the label is not advisable because the label represents legal guidance that must be followed, even in cases where state law may provide additional regulations. Similarly, while consulting with a safety officer could provide clarity in complex situations, the immediate action to take in the presence of conflicting REIs is to choose the lengthier one for added protection.
