Companion Guidance—Section F-3 CG AARST Companion Guidance RMS-LB 2018 Informational 13 Non-ASD —Example HVAC Inspection Checklist Inspected items that might reveal a need for system repair. Non-ASD Mitigation: HVAC Inspection Checklist Routine Operation and Maintenance Note: The information in this table is significantly drawn from EPA’s “Tools For Schools Action Kit” that inherently addresses indoor air quality issues that relate to many large buildings. Address: 26201Main, Building 10 System: #7 Date: Apr 10, 2014 Notes Staff : Inspection: Air Handling Unit Is the airflow from vents sufficiently meeting mitigation system design specifications? 1 2 1200 CFM JB Are the filters clean and properly installed? Replaced JB Are dampers operating correctly X JB Inspection: Controls, Temperature and Humidity Are the control settings and thermostat set to properly meet mitigation system design specifications? X JB Observations that may warrant further investigation/remediation: • Is air flowing from the vent too cool or too warm? • Does condensation frequently form on windows or cold surfaces? • Is there an objectionable odor? • Are areas in the building overly dusty? none JB Inspection: Outdoor Air Supply Is the ventilation system including related fans on? X JB Are outdoor intakes, vents or ducts blocked? X JB Is the airflow from vents sufficiently meeting mitigation system design specifications? 1 2 1200 CFM JB Is the airflow through outdoor intakes sufficiently meeting mitigation system design specifications? 1 2 250 CFM JB Observations that may warrant further investigation/remediation: • Are there reports from occupants regarding drowsiness or discomfort or other observations that suggest outdoor air supply is inadequate (i.e. < 15 cfm per person)? • Are combustion appliances in rooms without adequate ventilation? none JB 1 Airflow : To detect airflow, use special chemical smoke or a piece of tissue. Release puffs of smoke near openings between the complaint area and adjacent areas (openings include cracks, ducts, wiring and plumbing passageways, and leaky or open doors and windows). Release smoke near vents and grilles to determine airflow direction, if any. Do not breathe on or move quickly near puffs of smoke. 2 Air Volume: Flowhoods are designed to measure airflow at grilles and diffusers. Pitot tubes are designed to measure air velocity in ducts; air velocity is then used to calculate airflow. While flowhoods are more expensive to purchase than pilot tubes, they are easier to use and can be used to measure airflow in ducts by summing the airflows from all vents connected to a given duct.
