CC-1000 Companion Guidance (1-2018) CC-1000 Companion Guidance CG Page of 12 Informational 12 ANNEXES CC-1000 Discussion ANNEX A (Non-Normative) Inspections for compliance Any or all of the following inspections can be required by ordinance, contract or design specifications: A-1 Inspection prior to closure over soil by concrete or soil gas retarders for design, proper materials and secure fastening. A-2 Inspection prior to indoor finishings to verify plenum sealing and closure. A-3 Inspection prior to completion of indoor finishings to verify exhaust vent pipe compliance. ANNEX B (Non-Normative) ASD fans Fan installation can be required by ordinance, contract or design specifications. ANNEX C (Non-Normative) Radon test kits Ordinances, contracts or design specifications can require that radon test kits be provided as a tool to help verify occupant health and safety. ANNEX D (Non-Normative) Testing prior to occupancy Ordinances, contracts or design specifications can require testing prior to occupancy to help verify occupant health and safety.

WC [254 m 3 /hr @ 500 Pa ] (6 inch) [15 cm] Fan Type: RF2 RF2 Minimum rating: 75 cfm @ 1.0 in. WC [127 m 3 /hr @ 250 Pa Fan Type: RF3 RF3 Minimum rating: 150 cfm @ 2.0 in. WC [254 m 3 /hr @ 500 Pa ] Radon Fan Types RF1, RF2 & RF3 minimum flow and pressure ratings are examples of manufacturer specifications. Fans needed are best determined by PFE evaluations described in Section 7 that are conducted after construction. For fans serving larger expanses or resistive soil gas transfer, both airflow capacity (cfm or m 3 /hr) and vacuum capacity (WC or pa) will often require additional capacity.
