Oregon Revised Statutes Food and Other Commodities: Purity, Sanitation, Grades, Standards, Labels, Weights and Measures § 634.740

(1) The governing body responsible for a school shall adopt policies and processes for ensuring that the integrated pest management plan coordinator for the school, or a designee of the coordinator, gives written notice of a proposed pesticide application at the campus to, at a minimum, parents and guardians of minor students, adult students, school administrators, faculty members and staff members. The plan coordinator or designee may give a written notice described in this subsection by any reasonable means, including but not limited to, electronic mail.

(2) In adopting policies and processes under subsection (1) of this section, the governing body shall consider the age of the students attending the school and consider which methods for transmitting notice are most likely to reach the intended recipients.

(3) Except as provided in this subsection, the plan coordinator or designee must give a pesticide application notice in a manner reasonably calculated to reach the intended recipient at least 24 hours before the pesticide application occurs. A notice must identify the name, trademark or type of pesticide products, the registration number assigned to each of the pesticide products, the expected area of application, the expected date of application and the reason for the application. If a pest emergency makes it impracticable to give a pesticide application notice at least 24 hours before the pesticide application occurs, the plan coordinator or designee shall send the notice no later than 24 hours after the application occurs.

(4) Except as provided in this subsection, if a pesticide is applied at a campus, the plan coordinator or a designee of the coordinator shall place warning signs around pesticide application areas beginning no later than 24 hours before the application occurs and ending no earlier than 72 hours after the application occurs. A warning sign must bear the words “Warning: pesticide-treated area,” give the expected or actual date and time for the application and provide the telephone number of a contact person. If a pest emergency makes it impracticable to place the warning signs at least 24 hours before the pesticide application, the plan coordinator or designee shall place the signs as soon as practicable but no later than at the time the application occurs.

(5) Failure to give notice or post warnings as required by this section does not create a cause of action for damages and may not be asserted as the basis for a per se negligence claim.
