What does REI mean and why is it important?

• A. Reentry Interval; the period after application during which entry is restricted for workers for safety.
• B. Restricted Entry Interval; the period after application during which entry is restricted for workers for safety.
• C. Relative Entry Index; a measure of safety.
• D. Residual Entry Indicator; a label on the product.

Answer: (B)

REI stands for Restricted Entry Interval, the period after a pesticide is applied during which workers are not allowed to re-enter treated areas or may enter only with the appropriate safety measures. This safety window is specified on the product label and varies because it depends on how toxic the product is and how long residues remain hazardous. It’s important because it reduces workers’ exposure to pesticide residues, protecting them from skin contact or inhalation as residues dry or dissipate. If entry is needed during this interval, the label dictates required PPE and procedures, and often entry must be limited to trained personnel. The other terms don’t reflect the standard label language: they aren’t the recognized safety concept used to describe the post-application entry restrictions. In short, REI is the mandated safe-entry period after application to protect workers.
