| 1. Make sure the hose attachment is connected to your vacuum cleaner properly. Turn on the vacuum cleaner to make sure the hose attachment is pulling air, and then turn off the vacuum cleaner. Sometimes the dust collection device will not fit correctly onto the hose attachment. If this is the case, you may use duct tape or electrical tape to tape the dust collector to the hose attachment. 2. Use the extension cord as needed to reach the marked area with the vacuum hose. 3. Remove both caps from sampling device. Place the caps in a location so you can find them after the test is completed. Attach the flat, round end of the sampler device to the end of the hose attachment of your vacuum cleaner. 4. Use the slanted end of the sampling device to collect your sample. Keep the slant end of the sampling device flush with the surface to be sampled. 5. Turn on the vacuum cleaner and start the watch or timer. Start timing the vacuuming procedure using the stopwatch. Try not to disturb the tape. Do not exceed the 5minute sampling period. 6. Vacuum the area contained within the duct or electrical tape. Do this by passing the sampling device over slightly overlapping, imaginary parallel lines within the sampling area for about 5 minutes. If necessary, adjust your rate of movement so that a total of 5minutes is used to vacuum the entire 18 square foot sampling area. 7. Move to the second room and repeat the vacuuming of the target area. After the sampling is completed, hold the sampling device upward toward the ceiling and turn off the vacuum cleaner. Re-cap the slant end of the sampling device so as not to lose the dust collected. 8. Avoid vacuuming up any large debris that is not dust. If you accidentally suck up the tape, point the sampling device toward the ceiling and turn off the vacuum cleaner. Pick the tape out of the sampling device. Turn the vacuum cleaner back on and return to vacuuming the sampling area. Be sure to account for lost sample time when you do this so you get a total of 5minutes of sampling time. 9. Separate the sampling device from the hose of the vacuum cleaner and re-cap the flat end of the device. 10. After the small caps are secured on the dust sampling device, make sure there is dust in the sampling container before you send it to the lab. If no visible dust is noticed, repeat the sampling procedure in both rooms in different locations until visible dust is present in the device. 11. If you lose the small caps, seal the openings completely and securely with duct or electrical tape. |
