Testing Instructions

1. Prepare your home by closing ALL windows and doors for 12 hours prior to opening the test kit. Keep the house in this “closed” condition for the entire exposure. Standard entry and exit are acceptable, but DO NOT leave any doors or windows open.
2. Your test must be conducted in the lowest livable space (as defined by the building code). This is usually a bedroom or living room in the basement. DO NOT place the test can in the crawl space, furnace room, or bathroom.
3. You will register your test can on the Accustar website once the test is complete, and you must know the start and end times of your exposure.
4. Peel the tape around the can & pop the top open. Save both the tape & the lid to reseal when exposure is complete.
5. Place the bottom half of the test can AT LEAST 36’’ above the floor & 36’’ away from exterior walls (as close to the center of the room as possible).
   DO NOT place near any vents or drains, and at least 4’’ away from any other objects.
6. Leave the can undisturbed for a minimum of 48 hours. Testing can be conducted for up to 4 days, but 48 hours is preferred. Be sure to record the start and end time!
