Oregon Revised Statutes Public Health and Safety § 453.245

(1) Art or craft material that is considered by the Oregon Health Authority to contain a toxic substance causing chronic illness may not be ordered or purchased by a school or school district for use by students in kindergarten and grades 1 through 6.

(2) Any substance that is a toxic substance causing chronic illness may not be ordered or purchased by a school or school district for use by students in grades 7 through 12 unless the substance meets the labeling standards specified in ORS 453.235.

(3) If the authority finds that, because the chronically toxic, carcinogenic or radioactive substances contained in an art or craft material cannot be ingested, inhaled or otherwise absorbed into the body during any reasonably foreseeable use of the material in a way that could pose a potential health risk, the authority may exempt the material from these requirements to the extent the authority determines to be consistent with adequate protection of the public health and safety.
