RMS-MF 2018 with 12/20 Addenda

All Systems (12/20 addenda) 34 ANSI/AARST RMS-MF 2018 (with 1220 addenda) Radon Mitigation Standards for Multifamily Buildings Exception: In the absence of a common or independently metered power source for the system as a result of client choices or other conditions, one of the following options is required: a) For ASD or non-ASD methods that manipulate air pressures between soil air and ground contact portions of the building, a stand-alone mitigation system shall be installed in each ground contact unit or dwelling that is independently electrically metered; or b) For non-ASDmethods that are not dependent uponmanipulating air pressures between soil air and ground contact portions of the building, a stand-alone mitigation system shall be installed in each unit or dwelling that is independently electrically metered; or c) Prior to installation the contractor shall: 1. Provide the client a written communication that includes the system’s annual electrical costs (specifically calculated for each systembased upon current local rates) and the following statement: “During future renovations, sales or vacancy of individual dwellings , the health and safety provided to occupants by the mitigation system may cease to exist without the occupant's knowledge. It is incumbent upon the client to inform the building owner(s) of their obligation in this regard for ensuring long-term operation and maintenance for the system and full disclosure of this possibility to future owners.”; and 2. Receive written communications to be included with documentation that include: a. a statement from the client that provides the client’s justification for why it is truly not viable to achieve independent or common electrical metering or multiple stand-alone systems); and b. a statement from the owner of the dwelling(s) or unit(s) that indicates: (1) acknowledgment of the electrical cost information provided by the contractor ; (2) acceptance of obligations for long-term operation and maintenance of the system(s); (3) agreement with the client’s justification; and (4) permission to proceed with the installation. 8.3.5.3 Intentional Collateral Mitigation (fan monitors) In accordance with Section 8.2 for systemmonitoring, one of the following options is required: a) Fan monitors are installed in each ground contact area divided for separate occupancy use that is served by this system for ASD or non-ASD methods that manipulate air pressures between soil air and ground contact portions of the building; or b) Fan monitors are installed in each area divided for separate occupancy use that is served by this system for non-ASD methods that are not dependent upon manipulating air pressures between soil air and ground contact portions of the building; or c) A program is instituted for routine inspection onsite or by remote telemetric management system regardless of monitor locations and in accordance with Section 10.5 ; or d) A fanmonitor is installed in a location that is accessible and visible or audible for occupants of the building. Note—12/20 addenda updates now continue for the remaining portions for Section 8. 8.4 Labeling 8.4.1 Label materials and lettering All labels shall be made of durable materials. All label lettering and other annotation on systems shall be of a color in contrast to the color of the background on which the lettering is applied. Theminimum lettering size shall conform to requirements a) and b) of this Section 8.4.1 . a) Label titles shall be with lettering of a height not less than 1/4 inch (6 mm). b) Additional informational text shall be with lettering of a height not less than 1/8 inch (3 mm). 8.4.2 Primary labels A system description label shall be placed on a primary component of each system, such as on duct piping near an ASD fan monitor, or within 12 inches (30 cm) of the electric service panel or other prominent location. Systemmonitor devices shall have a label on or in close proximity to the mechanism that describes how to interpret the monitor and actions to take if a monitor indicates fan failure or degraded fan performance.
