When the work environment is cold, the low ambient temperature can accentuate discomfort from cooling and may influence workers' selection of RPDs, potentially affecting protective efficiency. This study aimed to quantify facial cooling while wearing particle-filtering facepiece respirators in cold conditions. Six different RPDs were selected: two filtering facepiece respirators (FFRs), two powered air-purifying respirators with constant airflow (PAPRC) and two breath-responsive air-supplied respirators (PAPRBR). Ten volunteers (six males and four females) participated, using the RPDs during rest and exercise for 40 min at an ambient temperature of -20 °C. Skin temperatures on four areas of the face and the air temperature inside the mask were recorded throughout the test. In addition, accumulated moisture in the facepiece was measured. The mean face skin temperature (MFST) was calculated as the average of the four skin temperatures. The results showed that MFST declined, on average, to 12.9 °C, 17.7 °C and 21.8 °C when PAPRC, PAPRBR and FFR were used, respectively. In conclusion, the use of RPDs in cold conditions presents particular occupational health and safety risks. Moisture retention is high when RPDs are used in cold conditions, and accumulated moisture inside the facepiece may cause discomfort and impair visibility. PAPRC decreases facial skin temperatures to an uncomfortable level, while PAPRBR and FFRs reduce cooling in cold environments.

The model performance is reasonable, though further simulation studies or field-based studies with detailed exposure determinant data can be used to improve emission rate estimates and model performance. The emission rates calculated in this study can be used to reconstruct past exposures for epidemiologic and risk analyses, and assist with attribution of silicosis and lung cancer to work-related causes.

Even in areas where asbestos is no longer mined it can still be encountered in mine spoil, when rocks are disturbed by construction projects, and in other mineral products (eg talc and vermiculite), as well as in products made from asbestos and in uncontrolled disposal of those products. While chrysotile was the type of asbestos most commonly mined and used in the United States, amphibole (tremolite and anthophyllite) asbestos is widespread and was also extracted commercially for the manufacture of specific products. Analysts are called upon to recognize the varieties of asbestos when they are encountered. Amphibole asbestos exhibits variation in crystallinity and chemistry, and so it is important that samples where the range of these features is well-described are available. Tremolite and anthophyllite are important constituents of certain rock types, and both can occur in fibrous and nonfibrous crystal habits, and crystallinity and chemistry vary between and within occurrences. Therefore, it is useful to have available a range of samples exhibiting this variation as a reference for analysts and researchers. Tremolite asbestos from an abandoned mine at Cemetery Ridge, Arizona, and anthophyllite asbestos from an abandoned mine near Palm Springs, California, were analyzed using (i) a polarized light microscope with a determination of principal optical properties, (ii) spindle stage analysis using a polarized light microscope to determine whether individual fibers and bundles of the samples were polycrystalline or single-crystal cleavage fragments, (iii) x-ray diffraction, (iv) a transmission electron microscope, including energy dispersive x-ray spectroscopy, and selected area electron diffraction, and (v) electron probe microanalysis. Additional images were acquired with a field-emission scanning electron microscope and transmission electron microscope to show the diversity of appearance. The overall findings of the study indicate that the materials are tremolite asbestos and anthophyllite asbestos.
