Exhaust fumes, monitoring

Smoke and fumes. The exhaust from some rocket motors and the fumes from some munitions can give responses. Since monitoring with CAM in these situations is unrealistic, few problems should arise. 

The use of procedural controls should be avoided and considered as the "last resort" if appropriate engineering controls cannot be designed into the facfiity, process, or product. An example of the use of personal protective equipment (PPE) in lieu of engineering controls would be the use of a fume hood. While the hood has appropriate engineering controls such as a monitored exhaust flow and a physical barrier (the sash), the separation of the user... 

Daily and before-use inspections/tests. At a minimum, daily/before-use and quarterly inspection and testing should be conducted on fume hoods. The daily or before-operation inspection should consist of an airflow check. A simple qualitative check that can be used to check for proper airflow, exhaust, is the ribbon or tissue paper check. During this test, a ribbon or piece of tissue paper (be careful not to lose control of these for they could gum up the system) is placed at the hood opening to determine if it reflects directional airflow. Daily and before each use the hood gauges and monitors should be checked for proper operation within a predetermined range.
