Soil Gas Control Systems ANSI/AARST CC-1000 2018 in New Construction of Buildings 26 ANNEXES (Non-Normative) ANNEX D (Non-Normative): Conduct testing prior to occupancy. Post-construction testing is the only way to verify that occupants will not be exposed to hazardous soil gas. However, post-construction testing shall not be required unless specifically referenced in the adopting ordinance, contract or design requirements. Adoption : To ensure occupants will not be exposed to hazards from radon gas, cite Annex D-1 and/or Annex D-2 in the ordinance, contract or design specifications. D-1 Radon testing prior to occupancy. A radon test shall be performed prior to occupancy and shall be performed by a certified / licensed measurement professional. Testing shall be performed in accordance with applicable state protocols or requirements, or if there are no state protocols or requirements for the style of constructed building, in accordance with national standards that include, as applicable: ANSI/AARST MAMF “Protocol for Conducting Radon and Radon Decay Product Measurements In Multifamily Building” ; ANSI/AARST MALB “Protocol for Conducting Measurements of Radon and Radon Decay Products In Schools and Large Buildings” ; or ANSI/AARST MAH “Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes” . Where testing results are greater than the national action level, a certified / licensed mitigator shall be required to perform diagnostic tests and remediation action. Radon testing shall be required until radon concentrations below the national action level are achieved. D-2 Testing prior to occupancy for other soil gasses or vapors. Testing shall be performed prior to occupancy by a qualified measurement professional for the following soil gases or vapors of concern: Soil gases or vapors of concern: Reference source for action level: _____________________________________ _____________________________________ _____________________________________ _____________________________________ _____________________________________ _____________________________________ _____________________________________ _____________________________________ Where testing results are greater than the state or federal action level, remediation action and follow-up testing shall be required until soil gas concentrations below the action level are achieved. Fan activation and diagnostic evaluations by a qualified mitigation professional are commonly the first steps in such remedial actions.
