Which is a situation in which entry to a treated area is allowed before the REI expires?

• A. When the label explicitly allows entry for a specific task and the required PPE is worn.
• B. Only after 48 hours have passed.
• C. When no one is applying pesticides nearby.
• D. When the area has been re-sprayed.

Answer: (A)

Entry before the restricted-entry interval expires is allowed only when the product label provides a specific exception for a task and the required PPE is worn. The label is the controlling rule for safety, and if it explicitly allows a designated activity during REI, you may enter for that task while using the PPE it requires. This is the best answer because it ties entry permission directly to the label’s explicit allowance and protective gear. Other ideas like waiting a fixed 48 hours aren’t universal rules—REI length and conditions vary by product, and absence of nearby applications doesn’t remove the risk. Re-spraying can trigger a new application with its own REI unless the label states otherwise. Always follow the label for any entry during REI.
