9. Other
a. Paint
No peeling and/or flaking paint found.
If planned building renovation will damage paint or if peeling paint is discovered, lead testing may be
necessary. If peeling paint is found, send email to the building Principal and the Facilities Director
alerting them of the problem. Staff and teachers need to pick up any flakes of paint to prevent
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.
Location(s) of known peeling paint in building:
b. The following preventive measures are being taken to reduce lead exposure.
i. Play areas and toys are cleaned nightly.
ii.
Floors are mopped nightly.
