Person bailing is susceptible to exposure.
Person bailing is susceptible to exposure.
Disadvantages of the Device - Inefficient for collecting large volume samples. Disadvantages of the Device - No control over flow rates, thus can not adjust from high evacuation rate to lower sampling rate. Most designed to sample for low levels of contaminants. Disadvantages of the Device - Deep sampling requires large volumes of gas and longer cycles, thus increasing operating time and expense and reducing portability. Disadvantages of the Device - Sample chemistry may be altered from turbulence caused by high pumping rates.
