    Traversing stainless steel duct

    New here and sorry if this topic has already been covered, but what is protocol on traversing stainless steel duct? Is it an acceptable practice?

    Doing a survey on a hospital and don't have the time to go measure all the lab hoods and phoenix exhaust valves.

    I'm not a TAB guy but I don't see any difference. Airflow is airflow. Take your reading in the correct locations and should be no issues.

    What does your contract require you to record? You are in a hospital but don't have time to make sure hoods are safe to work in?

    Lab hoods / exhaust system works fine. Conducting an overall air flow survey on air handlers, return fans, and exhaust systems.
    The building has a huge negative pressure and the client wants a snapshot of the air systems. I know that stainless steel used for kitchen hood purposes produce high temperature and is thus frowned upon of doing a duct traverse. Not sure if the chemicals used here could potentially pose a problem with drilling holes in the duct.
