Restricted entry interval

Development of Risk-Based Restricted Entry Intervals... 

Re-entry intervals (also known as restricted entry intervals) provide a mechanism to reduce post-application exposnre potential by preventing entry to treated areas until an established interval of time (e.g. 24 h) has expired.

A pesticide s restricted-entry interval (REI) is the time immediately after application when entry into the treated area is limited. Some pesticides have one REI, such as 12 hours, for all crops and uses. Other products have different REIs depending on the crop or method of application. When two or more pesticides are applied at the same time and have different REIs, the longer interval must be followed. 

The label will specify the restricted entry interval (REI) for the product. The restricted entry statement inclndes the amount of time that must elapse after a pesticide has been applied and before it is safe to enter the treated area withont wearing fnll protective clothing and equipment. If this interval applies to only certain nses or sites, the label will say so. The label may also list posting reqnirements associated with the reentry interval. Refer back to Section II, part G, for information on restricted entry intervals (REIs) in connection with the Worker Protection Act.
