| • For residential sampling, EPA recommends taking a living room and bed room sample as a composite using the same vacuum dust collector for both rooms. Other areas should be sampled separately. • In the Common Living Area (family room or living room), select the sofa. In the absence of a sofa, select another commonly used chair. • Using the tape measure and the roll of tape, mark the corners of a 3 foot x 6 foot rectangular sampling area on the floor immediately against the sofa. Place the long side of the rectangle against the long side of the sofa. If the area cannot accommodate the recommended sampling area, adjust the dimensions accordingly Sample a total of 18 square feet. • For the bedroom, select the most frequently used bedroom. Using the tape measure and the roll of tape, mark the corners of a 3 foot x 6 foot rectangular sampling area on the floor immediately against the side of the bed where the resident is most likely to get in and out of the bed. If possible try to have the rectangular sampling area extend under the bed by 3 or 4 inches so that part of the sample goes under the bed. Place the long side of the rectangle against the long side of the bed. If the area cannot accommodate the recommended sampling area, adjust the dimensions accordingly Sample a total of 18 square feet. • Record the final sampling area you marked with tape on the lines next to the bedroom you sampled on this data sheet. • Areas other than the Living Room, Family Rooms, or Bedrooms may be sampled. If you choose to sample other areas, a separate vacuum dust collector should be used for each area. Please call the lab if you have any questions. |
