What is REI and how should it affect entry after application?

Running Entry Interval Re-Entry Interval Regulatory Entry Index Required Entry Instruction

Correct Answer:

Re-Entry Interval

Explanation:

REI stands for Re-Entry Interval. It’s the minimum amount of time that must pass after a pesticide is applied before people can re-enter the treated area without protective clothing. This interval is written on the product label and is set to protect workers from exposure to residue left by the spray or mix. How it should affect entry is simple: do not re-enter until that time has elapsed. If entry is unavoidable during the interval, follow the label’s directions, which usually means wearing the required PPE and limiting exposure. The length of the REI varies by product and formulation, so always check the label for the exact duration before returning to the treated area.
