Safesite SafeCWA Chemical Warfare Agent Detector
Part of the MSA SafeSite™ Hazardous Gas Detection System, simultaneously
detects and categorizes Chemical Warfare Agents ( CWAs ) in the event of a terrorist
attack. The ability of the SafeCWA unit to detect chemical threats effectively
helps first responders, law enforcement and government agents warn of and respond
to chemical weapons of mass destruction.
MSA’s SafeCWA Detector uses Surface Acoustic Wavelength (SAW) technology,
providing selective analysis to avoid misleading warnings and false alarms through
a thermally modulated sample collection method. SAW sensors convert chemical
or physical input into an acoustical variation. SAW chemical sensors take advantage
of their inherent surface sensitivity to function and are the preferred signal
processing components for varied applications. If a CWA is present, a qualitative
signal will be discreetly displayed on the unit. In addition, this signal will
also be conveyed via wireless RF link to the remote SafeCOM™ Command
Center, part of the MSA SafeSite Hazardous Gas Detection System.

SafeCWA unit is easily transported and mounted, and may be
battery or line-powered as a standalone unit. It may also be
integrated into the entire SafeSite Hazardous Gas Detection
System. The SafeCWA Detector also performs self- and system
checks with easy and economical field maintenance and operation.
Round-the-clock detection of CWAs, for the confidence and reliability
that you expect from MSA.
Surface Acoustic Wavelength (SAW) technology, a preferred technology for providing
complex signal processing that functions in a sturdy self contained unit, designed
to work in complex environmental conditions. The advantages of SAW chemical sensors
include high selectivity and fast response. The dynamic range of a SAW chemical
sensor is 5-6 orders of magnitude, dependent upon the chemical vapor being measured.
Excellent temperature stability and reliability as well as redundant pumps and
filters allow for easy operation and infrequent field maintenance and calibration.
High, consistent selectivity to concentrations of nerve and blister agents within
varied environments. Also wide sensor range for detection of organic compounds
from very light to very heavy volatile extremes, as the ability to detect various
vapors is determined by the molecular weight and partial vapor pressure. Operates
as stand-alone, wireless or permanently integrated small, rugged, and reliable
unit within the MSA SafeSite Hazardous Gas Detection System network.
