73 ANSI/AARST SGM-SF 2017 (with 1220 revisions) Soil Gas Mitigation Standards for Existing Homes Exhibit B Sample Posted Notice: “CONTRACTOR TO OCCUPANTS” Sealant Warning Dear Building Occupants, Important steps are being taken to lower the risk to residents in this building. The work has required application of sealants. [ ✓ ] Wet Caulk/Sealants . Take care to not step in or touch sealants until they are dry. [ ✓ ] Vapor from sealants: Common construction sealants used to prevent radon entry at foundations and other locations will normally emit vapors that contain modest amounts of certain chemicals generally referred to as volatile organic compounds. The emissions occur mostly during application, but also to a lesser extent as they dry to form an air-tight bond. While these chemicals are commonly used, some sensitive individuals may experience discomfort or other health effects when exposed to such chemicals. Symptoms that may indicate sensitivity to these vapors may include: nausea, headaches, dizziness, drowsiness and/or an allergic reaction. Special consideration should be made for the very young or elderly who cannot communicate symptoms experienced. If symptoms are observed: Leave the area immediately to breathe fresh air. Avoid further exposure. If symptoms persist, get medical attention. We thank you for your cooperation in helping to ensure safe and healthy homes. Sincerely, Radon Company, Anytown, USA
