Protective Shelter for Diffusive benzene tube

Protective shelter

The diffusive TD Tube for Benzene is deployed for 14-day fenceline monitoring at multiple points around petroleum refinery sites.

 

 

  • Meets specification of U.S. EPA 325A and UK HSE MDHS 104
  • Used to determine average benzene concentration in the range 0.5 to 500 ug/m3 over a two week period
  • Reusable

The tubes are standard-sized SilcoNert 2000 deactivated Stainless Steel TD tubes with Swagelock fittings; when they are deployed a diffusion cap is connected to one end. The diffusion cap works the same way as a front plate on a passive badge, and has a small screen inside which also keeps out particulates/insects. Tubes are deployed inside a custom-made shelter for outdoor use, which can hold up to 4 tubes at a time, and keeps them pointing diffusion-cap downwards.

The tubes are identified with a unique identification number and bar code, and the airflow cap placement arrows are also printed on the tube.
