RMS-MF 2018 with 12/20 Addenda

All Systems (12/20 addenda) 36 ANSI/AARST RMS-MF 2018 (with 1220 addenda) Radon Mitigation Standards for Multifamily Buildings b) System Monitors The system monitoring device(s) shall be provided a label in close proximity to the mechanism, such as a primary label or other label, that includes: 1. Information on how to interpret the monitor; and 2. What to do if a monitor indicates fan failure or degraded fan performance; and c) System Controls Where systems include controls for any mechanical equipment, including dampers, system controls shall have a label on or in close proximity to the control mechanism. General instructions for operation shall be provided and system control settings that existed at the time mitigation goals were achieved shall be clearly marked on the equipment, a label or provided with equipment instructions. 8.4.4 Label duct piping Interior duct piping shall be marked with not less than one label at each floor level to portray the system purpose, such as “Radon Reduction System” or "Soil Gas Control System." Informative advisory —For ASD systems, duct piping labels should be affixed at intervals not greater than 10 feet (3 m) along the developed length of piping. 8.4.5 Label electrical disconnects Disconnects such as switches or outlets providing power to plugged connections for mitigation system fans shall be labeled or marked to indicate their purpose. The label title shall identify that the disconnect as a component of a radon or, as applicable, soil gas mitigation system, such as “Radon Fan – Do Not Turn Off,” or “Radon Fan – Do Not Unplug.” Informative advisory —The circuit breaker(s) protecting the mitigation system fan circuit(s) should also be labeled with the text such as “Radon Fan” or “Soil Gas Fan.” 8.4.6 Label sealed components Certain components that are sealed to resist air movement between soil and indoor air shall be labeled in accordance with requirements in a), b), c) and d) of this Section 8.4.6 . a) Label Sump Covers Sump lids shall be identified with a label that portrays the lid as a component of a radon or, as applicable, soil gas mitigation system. Instructions, such as “Component of a Radon Reduction System. Do not tamper with or disconnect” are recommended but not required. b) Label Crawl Space s or Membranes Where soil gas retarder membranes have been installed, a label or marking shall be located in a conspicuous place or places such as at access panels or immediately visible once entering the crawl space , such as on membrane material near the access location. The label shall include: 1. A label title that states “Radon Reduction System” or "Soil Gas Control System” or otherwise indicates the presence of a mitigation system component; and 2. Instructions, such as “Do Not Alter. Damage or alteration to plastic membrane sheeting can negatively impact system performance”. c) Label Access Locations into Non-habitable Airspaces and Sealed Isolation Assemblies Where mitigation methods address air within a non-habitable airspace or other sealed isolation assembly that can be accessed, labels shall be provided in a conspicuous place on the outside of access ports, hatches and doors into the airspace or immediately visible once entering the airspace. The label shall include: 1. A label title that states “Radon Reduction System” or "Soil Gas Control System” or otherwise indicates a presence of a mitigation system component;
