The waiting period after a pesticide application during which workers cannot enter without PPE is called what?

• A. PPE Access Window
• B. Re-entry Time
• C. Restricted Entry Interval (REI)
• D. Safety Entry Delay

Answer: (C)

Restricted Entry Interval is the official term used on pesticide labels for the waiting period after application during which entry to the treated area is limited and requires the specified PPE. This interval protects workers from exposure to residues by defining both the time that must pass and the protective equipment that must be worn if entry is allowed. The label sets the exact duration and PPE requirements, and entering during this period without complying with those requirements would violate the label. Other terms aren’t standard label language, so they don’t accurately describe this protective waiting period.
