Andrew, received the following from you but don't see where a reply can be posted:

 

I have a customer with vermiculite in the attic. I don't want the liability of running a Blower Door test, and made the case to the customer why it's not a good idea to test. However, he is willing to sign a waiver stating that he would not hold me be liable. Question: does anyone run the Blower Door (or duct blaster) with known vermiculite or asbestos in the home? Is the waiver a good idea?

 

I would be cautious of relying on any type of waiver. The law takes a dim view of a professional who tells the consumer that something is dangerous but that they can sign a waiver. Not worth the risk IMO, but I'm not a lawyer and don't play one on TV.

 

What about pressurizing the house with the blower door instead of depressurizing?
