This standard addresses a wide range of multifamily buildings including, among others, the use of a building or structure, or a portion thereof used as townhouses , apartment houses, convents, dormitories, military congregate residences, fraternities and sororities, and nontransient boarding houses, hotels, live/work units , monasteries, motels and vacation timeshare properties. 4 1.1.1 The techniques addressed in this standard provide whole building consideration yet also apply when implemented to portions of a multifamily building or individual dwelling . 1.1.2 This standard pf practice addresses a wide range of mitigation methods and is applicable to structures be they rented or owned including condominiums, co-op owned buildings and timeshare properties. 1.2 Limitations 1.2.1 Water and building materials This standard does not address all mitigation techniques such as may be needed for airborne radon that results from radon in water, building materials or other less common sources of radon gas. 1.2.2 Mitigation of other soil gasses (e.g., chemical vapors) When applying radon mitigation techniques herein for other hazardous soil gasses such as for chemical vapor intrusion into buildings. Applicable requirements are found in ANSI/AARST SGM-SF “Soil Gas Mitigation for Existing Homes ” to include Section 11 (Health and Safety) and Section 13 (Additional Requirements). 1. 2.3 Mixed-use buildings or complicated ventilation When portions of building are used for non-residential purposes and/or contain ventilation systems more elaborate than basic heating and cooling, see ANSI/AARST RMS-LB “ Radon Mitigation Standards for Schools and Large Buildin gs” for appropriate additional practices. 1. 2.4 Jurisdictional compliance This standard does not contain all code or other requirements of the jurisdictions where the radon mitigation system is being installed. Although the provisions in this standard have been reviewed for potential conflicts with other regulatory requirements, adherence to this standard does not guarantee or supersede compliance with the applicable codes or regulations of any federal, state or local agency with jurisdiction. 1.2.5 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.
