Documentation (OM&M) 46 ANSI/AARST RMS-LB 2018 (with 1220 revisions) Radon Mitigation Standards for Schools and Large Buildings Table 10.5 Operation, Maintenance and Monitoring (OM&M) Plans Documentation Controls and Mechanical SystemMonitors Maintenance Inspections of Controls and Monitors Frequency of Inspection Document Startup Details A description shall be provided for the fan monitors, control settings and other operating parameters that existed at the time successful mitigation was initially achieved. Note—The description should include explicit detail for comparison during inspections and repair, including: a) descriptions of equipment labeling and annotations for fan monitors, control settings and other operating parameters; b) exact locations of fan monitors, electronic telemetry/monitoring equipment, electrical disconnects and other components; c) instructions for equipment sufficient to interpret labels, annotations and the designed operating parameters for the equipment. When applicable, include manufacturer instructions; d) a list of appropriate actions for the client (s) to take if fan monitor devices or inspections indicate a system is not operating as designed; and e) documented measurements for balance of airflow in and airflow out of HVAC system(s) when a component of a mitigation system. The following inspections shall be written into the OM&M plan as required actions: a) inspection of fan monitors, control settings and other operating parameters to ensure systems are operating as designed; b) investigation and correction of any conditions that are found to indicate component failure or inconsistencies with designed operating parameters; c) recording and maintenance of records that are to be assimilated into the overall building OM&M documentation; and d) The plan shall stipulate that a qualified professional should perform these inspections and if performed by in house maintenance staff, such staff shall be trained in system operations. The plan shall stipulate recommendations and any requirements for the frequency of inspections, as deemed by the contractor as appropriate to the situation. Note 1—It is recommended that the plan stipulate inspections be conducted at least quarterly of all fan monitors, controls, and as applicable, filters and vent openings. Note 2—The plan should recommend inspections subsequent to: a) system shutdown due to building power failure or emergency; and b) any catastrophic event that could damage system components. Documentation Mechanical Equipment Mechanical Equipment Inspections Frequency of Inspection Equipment Details and Instructions a) Include manufacturer instructions and instructions specific to design configurations, as appropriate; b) Include exact locations of fans, electrical disconnects and other components; and c) Include a list of appropriate actions for the client (s) to take if the fan monitor warning device indicates system degradation or failure. d) Include a list of potential repair items for ASD systems that should include: i. fan monitor repair or replacement (e.g., reconnect or replace oil in U tube); ii. electrical repair; iii. fan or boot replacement; and iv. sealing openings to soil or piping connections. The OM&M plan shall observe that mechanical equipment inspections should include all seals, straps, fasteners, electrical system (including switch operation), boots, performance indicators, labels, pipe condition, filters, inlet grills and fan operation. When HVAC is a component of the mitigation system(s), provide a list of inspection items that includes: i. HVAC airflow in and airflow out of the air handler; ii. functionality of HVAC filters; iii. room differential pressure test; iv. fresh-air damper settings; and v. verification for supply air into rooms of interest. The plan shall stipulate that a detailed inspection of all components is to be conducted at least every 2 years by a qualified professional. Monitoring Continued Effectiveness The plan shall include notice of applicable retesting guidance found in ANSI/AARST publication MALB: Protocol for Conducting Measurements of Radon and Radon Decay Products In Schools and Large Buildings .
