and fan dry. For areas greater than 9 square feet, replace carpet with tile in reasonable timeframe. If
carpet is over ACM tile, replace during next unoccupied break time (winter break, spring break,
summer).

children from being exposed. The Facilities Director will advise the Facilities Coordinator (a Certified
Lead Paint Renovator) to test the paint for lead. Lead paint was discontinued in 1978. Buildings built
after 1978 are exempt from lead paint testing.
If lead is present, required repairs should be done immediately using lead-safe methods and, if
necessary, a licensed lead contractor.
