First responders to illicit drug labs may not always have SCBA protection available. Air-purifying respirators using organic vapor cartridges with P-100 filters may not be sufficient. It would be better to use a NIOSH-approved CBRN respirator with it

Testing of the permeation resistance of eight glove and suit barriers against commercially available substituted silanes and siloxanes was performed using the ASTM F739-96 standard test method. In addition to barrier performance to the pure organosil

Cartridge service life is not appreciably affected at relative humidities below 50%. However, performance is severely compromised when the humidity exceeds 65%. Experimental values are compared from those calculated from the adsorption isotherm, Meck

Four systems have been fabricated to measure the effective service life of respirator cartridges and canisters;. The four systems employ carbon monoxide, sulfur dioxide/nitrogen dioxide, ammonia/methylamine, and chlorine/hydrogen chloride as contamin

Although polarized electrostatic air filters are efficient air filtrating devices, their main disadvantages are difficulty in collecting conductive particles or in operating at relative humidities above 70%. We describe here a new filter design that

The theory of solvent vapor adsorption of activated carbon is reviewed. Calculated and experimental cartridge service life values are compared using various breathing rates, relative humidities, concentrations and solvent vapors. Cartridge service li

Airborne halogen compounds have been found to greatly increase the intensity of the N2and NO molecular spectra of air in an ac spark. Chlorinated materials cause the largest enhancement followed by brominated, iodinated, and fluorinated compounds. Th

The service life of organic vapor respirator cartridges has been evaluated for steady-state and pulsating flow rates; a mechanical breathing simulator was used to evaluate the pulsating flow rates. Two types of cartridge have been tested at work rate
