| (75) Target housing--Any housing constructed prior to 1978, except housing for the elderly or persons with disabilities (unless any child who is six years of age or younger resides or is expected to reside in such housing) or any zero-bedroom dwelling. As defined in this section, target housing includes the terms residential dwelling, multi-family dwelling, and unit. (76) Testing--The collection of paint, soil, or dust-wipe samples for determining the presence of lead in paint or lead-based paint hazards by an EPA recognized laboratory or the use of an XRF. (77) Training curriculum--An established set of course topics for instruction in an accredited training program for a particular discipline designed to provide specialized knowledge and skills. (78) Training hour--At least 50 minutes of actual teaching, including, but not limited to, time devoted to lecture, learning activities, small group activities, demonstrations, evaluations, and/or hands-on experience. (79) Training manager--The individual responsible for administering a training program and monitoring the performance of principal instructors and guest instructors. (80) TSCA--Toxic Substances Control Act (15 United States Code §2681 et seq) Title IV. (81) Unit--A room or connected group of rooms used or intended to be used by a single tenant or owner. (82) Visual inspection for clearance testing--The visual examination of a residential dwelling or a child-occupied facility following an abatement to determine whether or not the abatement has been successfully completed, as indicated by the absence of visible residue, dust, and debris. (83) Visual inspection for risk assessment--The visual examination of a residential dwelling or a child-occupied facility to determine the existence of deteriorated lead-based paint or other potential sources of lead-based paint hazards. (84) Weighted arithmetic mean--The arithmetic mean of sample results weighted by the number of subsamples in each sample. Its purpose is to give influence to a sample relative to the surface area it represents. A single surface sample is comprised of a single subsample. A composite sample may contain from two to four subsamples of the same area as each other and of each single surface sample in the composite. The weighted arithmetic mean is obtained by summing, for all samples, the product of the sample's result multiplied by the number of subsamples in the sample, and dividing the sum by the total number of subsamples contained in all samples. For example, the weighted arithmetic mean of a single surface sample containing 60 µg/ft2 , a composite sample (three subsamples) containing 100 µg/ft2 , and a composite sample (four subsamples) containing 110 µg/ft2 is 100 µg/ft2 . This result is based on the equation [60 + (3*100) + (4*110)]/(1+3+4). (85) Window trough--For a typical double-hung window, the portion of the exterior window sill between the interior window sill (or stool) and the frame of the storm window. If there is no storm window, the window trough is the area that receives both the upper and lower window sashes when they are both lowered. The trough is sometimes referred to as the window "well." (86) Wipe sample--A sample collected by wiping a representative surface of known area, as determined by ASTM E1728, "Standard Practice for Field Collection of Settled Dust Samples Using Wipe Sampling Methods for Lead Determinations by Atomic Spectrometry Techniques," or equivalent method, with an acceptable wipe material as defined in ASTM E1792, "Standard Specification for Wipe Sampling Materials for Lead in Surface Dust." (87) Working days--Monday through Friday including holidays that fall on those days. (88) Worksite--An interior or exterior area at a target housing or child-occupied facility where lead-based paint abatement activity is taking place or is scheduled to take place. (89) X-Ray Fluorescence Analyzer (XRF)--An instrument used to determine the concentration of lead in a sample; readings are in milligrams per square centimeter (mg/cm2 ). (90) Zero-bedroom dwelling--Any residential dwelling in which the living area is not separated from the sleeping area. The term includes, but is not limited to, efficiencies, studio apartments, dormitory housing, military barracks, and rental of individual rooms in residential dwellings. |
