13 SGM-SF Code examples: IRC® CHAPTER 41 APPLIANCE INSTALLATION E4101.3 Flexible cords. Cord-and-plug-connected appliances shall use cords suitable for the environment and physical conditions likely to be encountered. Flexible cords shall be used only where the appliance is listed to be connected with a flexible cord. The cord shall be identified as suitable for the purpose in the installation instructions of the appliance manufacturer. Receptacles for cord-and-plug-connected appliances shall be accessible and shall be located to avoid physical damage to the flexible cord. Except for a listed appliance marked to indicate that it is protected by a system of double-insulation, the flexible cord supplying an appliance shall terminate in a grounding- type attachment plug. A receptacle for a cord- and-plug-connected range hood shall be supplied by an individual branch circuit. Specific appliances have additional requirements as specified in Table E4101.3 (see Section E3909). SGM-SF Discussion CG SECTION 9.0 POST-MITIGATION (RADON) 9.1 Post-Mitigation Functional Inspection 9.2 Radon Retests After Mitigation An inspection of functional components is required after mitigation. The effectiveness of the system can only be determined by a radon test . CG SECTION 10.0 DOCUMENTATION (RADON) Long-Term Operation, Maintenance and Monitoring Plan An information packet with written instructions essential for maintaining and monitoring for system failure (i.e., OM&M plan) is required much as it has been required for radon systems since 1993. When the occupant does not maintain the system or when non-ASD methods are employed, additional content is required. CG SECTION 11.0 HEALTH AND SAFETY See SGM-SF Section 11.0 for important guidance and requirements associated with worker and occupant health and safety. CG SECTION 12.0 NON-ASD METHODS 12.1 All Non-ASD Methods 12.2 Sources for Air Delivered to a Building 12.3 Indoor Air Pressurization 12.4 Soil Air Pressurization 12.5 Indoor Air Dilution 12.6 Soil Air Dilution 12.7 Controls for Variable Activation 12.8 HVAC Repairs or Modifications 12.9 Building Materials Source 12.10 Radon FromWater 12.11 Chemical Vapors FromWater 12.12 Air Cleaning 12.13 Source Removal 12.14 Passive Systems/Technologies FUNDAMENTAL OVERVIEW Protecting people from hazardous air entails either 1) Moving the hazardous air or source of air away from people 2) Encapsulating the hazardous source, or 3) Diluting the hazardous air ASD moves hazardous air away from people by manipulating the pressure relationship between soil and indoor air. But each method overlaps to some degree with the other two methods. Most Non-ASD methods for reducing indoor concentrations of airborne hazards include manipulation of building pressures or air change rates (i.e., dilution). Advisory – Such activities can prove fruitless or even hazardous if not conducted by a professional who is trained in disciplines associated with related building science.
