Researchers at the University of Saskatchewan (U of S) are on a way to plan a ventilation system that will act as a shield for the buildings, against chemical warfare and bioterrorist attacks.

It was a four year task for Kozinski to develop the early warning and response system (eWAR). The system is well equipped to find, identify and trap molecules. Moreover, it sets off an alarm that acts as a signal pointing out that something is wrong with the air.

The eWAR system also manages to kill the viruses with its ultraviolet light. Thus, the system stops the spread of infections.

The eWAR sensor, Traker, made by the Alert B and C company in Quebec, calculates the mass of the molecules in “milliseconds” and identifies them easily.

According to Suzanne Lebel, chairperson of Alert B and C, places such as airports and government buildings should be the first ones to be equipped with the e WAR system.

Kozinski, hopes the eWAR system to be available in market by 2010. However, no manufacturers of the system have been found so far.
