2 ANSI/AARST RMS-LB 2018 (with 1220 revisions) Radon Mitigation Standards for Schools and Large Buildings 1.2.4 Safety This standard is not intended to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices. It is the responsibility of the user of this standard to determine the applicability of regulatory limitations prior to use. 1.2.5 Design and warranties This standard is not intended to be used as a designmanual, and compliance with its provisions will not guarantee reduction of indoor radon to any specific concentration. 2.0 APPLICABILITY 2.1 Mandatory Conventions The terms “shall”, “required” and “normative” indicate provisions herein that are considered mandatory. Terms such as “should,” or “recommended” and provisions prefaced by the term “Note” or “Informative” indicate provisions that are considered to be helpful or good practice, but which are not mandatory. 2.2 Prior Systems This standard shall not apply to radon mitigation systems installed prior to its effective date, except when a previously installed system is altered. This standard shall apply to only the aspects of the system that are altered, and the contractor shall recommend to the client in writing that the noncompliance items be upgraded or altered to meet current standards. For the purposes of this standard, altering a radon mitigation system does not include activities such as replacing worn out equipment while leaving the remainder of the system unchanged. 2.3 Adoption and Use These standards of practice can be adopted as requirements for contractual relationships or adopted as recommendations or requirements of an authority or jurisdiction. To the extent the minimum requirements of this document exceed local, state or federal requirements for the locale in which the mitigation is conducted, then this document’s minimum requirements shall be followed. 3.0 QUALIFIED CONTRACTORS 3.1 Trained Professionals The practices outlined in this standard are intended for the use of a contractor or management teams among which at least one individual is specifically trained in the technology of radon reduction. 3.2 Contractors, Teams and Qualifications Persons qualified in varied disciplines with different skill sets are needed to accomplish radon reductions in many schools and large buildings. The contractor , contracting team or management team shall include individuals who have appropriate technical knowledge, skills and experience required to mitigate schools and large buildings, including at least one “QualifiedMitigation Professional.” Persons including radon professionals shall be qualified for their apportioned task. 3.2.1 Qualified mitigation professional A “Qualified Mitigation Professional” for the purposes of this document is defined as: “An individual that has demonstrated a minimum degree of appropriate technical knowledge and skills specific to radon mitigation of schools and large buildings: a) as established in certification requirements of the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB); and b) as required by statute, state licensure or certification program, where applicable. Responsibilities Responsibilities for qualified mitigation professionals include compliance with this standard and tasks identified in Section 5.4 (investigations prior to design) and Section 8.5 (inspections subsequent to installation). Sections 4.2.2 and 10.1.1 f require that the qualified mitigation professional be identified in documentation. 3.2.2 Other qualified professionals Informative advisory —Other persons working with the contractor or management team (e.g. design, utilities, engineering and facilities staff) should be qualified for their discipline. Such persons should maintain applicable licenses or certifications and acquire permits as required by the jurisdiction where the mitigation work is performed.
