What does the REI (Restricted Entry Interval) indicate on pesticide labels?

• A. The time period required before unprotected individuals can safely re-enter a treated area
• B. The length of time a pesticide remains effective after application
• C. The number of days after which re-application is necessary
• D. The maximum time allowed for workers to wear protective equipment

Answer: (A)

The REI, or Restricted Entry Interval, is a critical safety guideline found on pesticide labels, indicating the time period required before unprotected individuals can safely re-enter a treated area. This interval is established to protect workers and others from potential exposure to pesticide residues that may be harmful if inhaled or absorbed through the skin shortly after application. The determination of the REI takes into consideration the toxicity of the pesticide, its application method, and environmental factors, ensuring that individuals who do not wear protective gear can avoid health risks associated with direct exposure. Once the REI has passed, the treated area is considered safe for entry without protective equipment, thereby contributing to safe agricultural practices and minimizing health risks related to pesticide use.
