Task Instructions or Training associated with each task QMP's Required Outcome Identify test locations within a room Sufficient to know where not to test and required distances away from floors; ceilings; exterior windows, doors, and walls; and other devices and objects. - Devices deployed in compliance with Table 3.8 Manage devices or detectors and documentation during placement and retrieval Sufficient to document test locations, device serial numbers; start and stop dates and times; and where QC check devices were deployed. Sufficient to update addresses and document occupancies, conditions and mechanical systems that are different than anticipated. Sufficient to document and seek guidance if test reliability concerns are encountered. Sufficient to use devices in compliance with manufacturer’s instructions. - 6.4.2: Documented details are recorded that are required for processing test result analysis and reports - 6.4.1: Updated records and floor-plan diagrams - 2.3: Devices used in compliance with manufacturer instructions Identifying which dwellings and rooms are to be tested Sufficient to understands which dwellings and rooms to test, compared to where not to test. Sufficient to seek guidance and document locations that were designated to test but could not be tested or where a valid test could not be completed due to missing, lost and non-retrievable detectors - 3.0: The required dwellings and rooms are tested - 6.2: Locations intended to test but did not achieve a valid test are identified Quality control of test conditions Sufficient to inspect for and understand when closed- building conditions were not or cannot be maintained; and to seek guidance if unanticipated conditions are encountered. Sufficient to ensure “radon test in progress” notices are posting in conspicuous locations. Sufficient to identify unexpected HVAC conditions, that can include variable outdoor air ventilation, variable air volume systems and return air ducts under slabs. - Tables 4-A, 4-B and 4-C and 6.1.1, 6.1.2, 6.1.5 and 6.1.7: Compliance with closed-building requirements - 6.1.6: “Radon test in progress” notices are posted "QC" measurements Sufficient to integrate duplicate and blank measurement detectors, where instructed. - 6.3: QC measurements are conducted and reported Temporary conditions and protocol deviations Sufficient to understand, document or seek guidance on temporary conditions and deviations from protocol that may adversely affect test reliability - 8.2.3 Report conditions that may adversely affect test reliability
