An environmental audit should be conducted before construction of a new building; renovation or occupation of an older building; or after a natural disaster to properly evaluate and, where necessary, remediate or avoid sites where children's health could be compromised. A written report that includes any remedial action taken should be kept on file. The audit should include assessments of:
a) Potential air, soil, and water contamination on program sites and outdoor play spaces;
b) Potential toxic or hazardous materials in building construction, such as lead and asbestos; and
c) Potential safety hazards in the community surrounding the site.
