Gastec Irritant Smoke Tube Kit:
Respirator fit testing & Airflow indication

Includes 1 box of irritant smoke tubes (6 per box), aspirator bulb, tube caps and carrying case. (smoke tubes are reuseable)

Irritant smoke is the only OSHA-accepted qualitative fit testing method that does not rely on the test subject’s subjective response. Other types of qualitative fit tests, such as banana oil (Isoamyl acetate), saccharin, or Bitrex, may cause false negative results.

Nextteq Irritant Smoke Tube Kits are quick, simple, and economical to use for respirator fit testing and airflow indication. The kits contain everything needed to perform multiple fit tests.

Each aspiration bulb pump and Gastec irritant smoke tube is pre-calibrated and ready for immediate use. There is no warm-up time or calibration required. Also, there are no special sensitivity test chemical mixtures to prepare in advance.

Using the Nextteq Irritant Smoke Tube Kit for airflow indication is a simple and effective method for tracing and determining the source, direction, and dispersion of air currents. The highly visible white smoke provides an immediate and obvious cue to the directional pattern of air currents.
