Information : Toxic Fumes Measurement
CSTA has improved its ability to measure levels of toxic fumes and gases in the confined spaces of vehicles during a testing. Before 1983, the only dedicated real-time analyzers available were for carbon monoxide, NH3, and nitrogen dioxide. Samples of other species were collected with vacuum cylinders for laboratory analysis with a gas chromatograph. Since 1983, however, significant improvements have been made in the equipment capabilities.
CSTA performs toxic fume and gas measurements on live fire (vulnerability), automotive, weapons, and fire extinguishing systems in an effort to protect soldiers from the effects of toxic fumes and gases. Fumes can originate from the firing of the gun on a tank, the exhaust from the engine on the tank being ingested into the ventilation system, or from the tank being hit by a round of ammunition. CSTA monitors and analyzes the air in the inhabited sections of the vehicle during test operations to detect any toxic gases produced. Real time analysis is performed for CO, CO2, NH3, SO2, NO2, NO, Halons, and O2 depletion. Collection for laboratory analysis is performed for total particulates, respirable particulates, HF, HCl, HBr, and HCN acid mists, fuel and oil mists, aldehydes, ketones, organic compounds, and Pb, Cu, and other metal fumes.
Toxic fumes measurement requires several different pieces of equipment including:
Non-dispersive infrared analyzers for CO, CO2 , Halons, ammonia (BINOS IR) Non-dispersive ultraviolet-visible analyzers for SO2, NO2 (BINOS UV/US)
Paramagnetic analyzers for O2 (Rosemount)
Chemiluminescent analyzers for NO, NO2 or NOX (TECO)
Portable electrochemical monitors for CO, O2 , NO2 , SO2 and combustible gases (Exotox)
Portable photoacoustic infrared analyzers for numerous gases/vapors (B&K)
Pulsed fluorescent analyzers for SO2 (TECO)
FTIR spectrometer (gases)
ICP spectrophotometer (metals)
