At such times, effective decontamination of personnel and equipment is an essential component of a hazard mitigation strategy. The current decontamination practices used for firefighter protective clothing have been shown to not be very effective. Hence, the scientific community is looking for several alternatives to conventional washing procedures. Liquid carbon dioxide (CO2) has been used in laundering and has distinct advantages over conventional dry-cleaning solvents such as perchloroethylene. The following study is aimed to assess how different washing procedures affect the durability of the turnout material. The study includes using three washing procedures on different samples: 1) conventional washing procedure, 2) liquid CO2 washing procedure, and 3) a high-temperature washing procedure. Samples for durability testing were constructed from a common aramid fabric used in firefighter turnout ensembles. These swatches were subjected to different washing techniques. The durability assessment was performed for physical testing of the samples, visual inspection, water repellency, and quantifying color changes using spectrophotometric analysis. The conventional wash and high-temperature washing affected the durability of the outer shell material in a significant manner. The liquid CO2 process did not affect the samples’ water repellency or physical strength. In contrast, conventional and high-temperature washing significantly affected the durability of the outer shell material. However, all samples met the criteria for tearing strength outlined in the NFPA 1971 standard subsection 7.1.11.}, journal={FRONTIERS IN MATERIALS}, author={Girase, Arjunsing and Thompson, Donald B. and Ormond, R.

It is the only approved device for use in determining the localized and systemic protection factors for chemical protective ensembles. In MIST evaluation protocols, PADs are placed on test subjects underneath the protective suit, and then the test subject is exposed to a known concentration of methyl salicylate (MeS), a warfare agent simulant. The purpose of the PADs is to collect the MeS vapors that enter the suit at seams, closures, or interfaces between the protective suit and gloves, boots, or the breathing apparatus. Given this key role, it is imperative that the diffusive uptake rates associated with the PADs are characterized. It is equally important to fully understand the factors influencing these rates. This research investigates two different categories of influential factors: the variation in adsorption rates associated with the simulant concentration and exposure time, and the relation to the effect of the time and temperature of the PAD's storage prior to extraction and analysis. For the first study, PADs were exposed, in the full scale MIST Facility at North Carolina State University, to concentrations ranging from 15 to 100 mg/m3 for exposure times ranging from 1 min to 2 h in duration. In the second study, the effect of the storage time prior to analysis was determined by exposing PADs at a set condition and varying the amount of time before the PADs were extracted. In order to assess the effects of storage temperature on the uptake rate, PADs were exposed and stored at temperatures ranging from below −30°C to 4°C. The findings of this research help identify and explain a possible source of differences that have been observed in MIST results at different testing sites. This work also provides a deeper understanding of the characteristics of the PADs themselves.}, journal={PERFORMANCE OF PROTECTIVE CLOTHING AND EQUIPMENT, 9TH VOL: EMERGING ISSUES AND TECHNOLOGIES}, author={Ormond, R.

Three types of electret filter media were exposed to xylene in liquid and gas phases. Experimental data indicated that the penetration percentage of di-octyl-phtalate (DOP) aerosols through electret filter media was not influenced by exposure to xylene vapors for periods up to 8 h. The filtration performance for all three types of electret filter media decreased over 30% when the samples were exposed to liquid xylene. Pressure drop changes of the filter media prior and after exposure to liquid xylene were statistically negligible. Neither morphological changes nor degradation of the polymer fibers were observed after exposure of the filter media samples to liquid xylene. Thermodynamic simulations were performed to determine the molar flux of liquid and gas phases through the filter media specimens. Experimental results obtained via capillary gas chromatography were within 4% of the predicted values. The decrease in performance was attributed to changes in the density and spatial distribution of the electret charges on the surface of the polymer fibers.}, number={7}, journal={JOURNAL OF AEROSOL SCIENCE}, publisher={Elsevier BV}, author={Jasper, W. and Hinestroza, J. and Mohan, A. and Kim, J. and Shiels, B. and Gunay, M. and Thompson, D. and Barker, R.}, year={2006}, month={Jul}, pages={903–911} }
