Once your have made a sampling appointment, you'll need to do a few things around your house to ensure the test produces an accurate result.

  • If you have chemicals in your home, look for those described on this page. Check the labels. In particular, look for the chemical trichloroethene, or its synonym, trichloroethylene. If you find a product with this chemical listed on its label, show it to the sampling team when they arrive to place the sampling device.
  • The device will be placed in the lowest livable space in your home, ideally 3 to 5 feet above the floor. The technicians will work with you to find a suitable place. 
  • Continue to live your life as normal. You can do most of the things you would normally do. You don't need to leave the house and you won't need to take any special precautions.
  • Make sure the sampling team has access to your basement or lowest livable space.
  • Avoid working on hobby projects that use paint, glues or other chemicals. White glue is okay, but avoid glues that are in glass bottles or metal tubes. If you have any of these types of glues, please identify them to the sampling team.
  • When the technicians come to place the sampling device, they will ask you a few questions. This will help them determine where best to place the sampling device and find out what chemical products you have in your home.
  • Gun owners, avoid cleaning your guns in the home during the sampling period and make sure any cloth or brushes used in cleaning are moved outside. Some gun cleaners contain trichloroethene. Cleaning your guns could cause a detection and dirty rags could still emit detectable levels of TCE vapors.
  • While the sampling device will be placed out of the way, try to avoid contact with the device.
