Physical, mechanical, and fire properties of the injection-molded wood flour/polypropylene composites incorporated with different contents of boron compounds; borax/boric acid and zinc borate, and phosphate compounds; mono and diammonium phosphates were investigated. The effect of the coupling agent content, maleic anhydride-grafted polypropylene, on the properties of the composites with fire-retardant was also investigated. The composites with the zinc borate had the highest dimensional stability and strength in the bending, tensile, and izod impact, followed by the monoammonium phosphate, borax/boric acid, and diammonium phosphate treatments. The treatments produced modest improvements in fire performance as indicated by reductions in the heat release rates. Best results were achieved with the phosphate treatments. The Scanning Electron Microscope-Energy Dispersive Spectroscopy elemental mapping of the samples revealed that the outer surface of the wood fibers was coated by some crystalline deposits of the fire-retardants. © 2012 Elsevier Ltd.

An important characteristic of liquid sprays is the statistical distribution of droplet sizes that they produce. Knowledge of the droplet size distribution is particularly important for pesticide applications because droplet size affects trajectory, probability of contact with the target pest, and the biological dose. This article describes an experimental study of the spray plume of a rotary-cage atomizer in a wind tunnel environment with an air speed typical of aerial application (60 to 70 m s-1). Comparative measurements of droplet velocity and diameter were made using phase Doppler interferometer (PDI) and laser diffraction (LD) instruments. The present study is unique because it reports full droplet velocity and size data over a range of streamwise distances from the atomizer. High droplet concentrations and strong flow recirculation in the near wake (x/D < 2) were found to have a significant effect on the LD measurements. At greater downwind distances (x/D > 8), droplet velocities were found to be more uniform, and droplet size measurements using LD and PDI instruments were found to be in close agreement. © 2012 American Society of Agricultural and Biological Engineers.

This study provides a literature review of prior research on respiratory exposure for fire fighters and other emergency responders, and includes an information collection effort that provides a summary review of field measurement technology and selected fire department Standard Operating Procedures and Standard Operating Guidelines (SOPs/SOGs) relating to respiratory exposure. The purpose of this study is to raise awareness on the need for emergency responder respiratory protection, promote and support specific fire service respiratory exposure related research, and to help develop best practice fire service guidance for determining when to use and discontinue use of self-contained breathing apparatus (SCBA) and other respiratory protective equipment. The applications of primary focus include atmospheres that are possibly hazardous yet tenable, such as during overhaul operations, fighting outdoor fires, or limited exposure situations. © 2009 Springer Science+Business Media, LLC.
