Collecting the Sample

1. Mark about a 1 inch section of insulation, including a joint if distinct join compounds are present bonding the sections of insulation.

2. The shaving foam can be used to minimize dusting at the sample site. Simply deposit a small quantity of foam along the lines where insulation will be cut. Additional shaving foam can be applied anytime dusting is a concern.

3. Cut through the material to the pipe and remove the insulation.

4. At least a 1 inch piece of insulation should be collected.

5. Place the insulation sample in the plastic bag.

6. Seal the bag.

7. Write the location of the sample on a piece of paper and deposit the sample bag and the piece of paper in a second plastic bag.

The finished sample can be delivered to Microlab Northwest or mailed if well sealed and solidly packaged.
