Sound attenuation performance of fiber reinforced polymer composite circumaural hearing protection devices.

Augustine SC

2015/01/01 | National Institute for Occupational Safety and Health (NIOSH)

Personnel who work on the flight deck of an aircraft carrier are exposed to extreme levels of jet engine noise often in excess of 140 decibels (dB). The current circumaural hearing protective devices (CAHPD) employed by flight deck crewmen are inadequate for the level of protection required for these extreme levels of noise. Fiber-reinforced thermo ...

TY - Thesis AU - Augustine SC AB - Personnel who work on the flight deck of an aircraft carrier are exposed to extreme levels of jet engine noise often in excess of 140 decibels (dB). The current circumaural hearing protective devices (CAHPD) employed by flight deck crewmen are inadequate for the level of protection required for these extreme levels of noise. Fiber-reinforced thermoset polymer composite (FRPC) materials such as aramid fibers used in body armor, have high theoretical values of acoustic impedance due to a fundamentally high modulus of elasticity and may offer a superior level of hearing protection over original equipment (OE) thermoplastic CAHPDs. The objective of this project was to measure and evaluate the attenuation of CAHPD's constructed from FRPC materials. FRPC CAHPD ear cups were paired with OE thermoplastic CAHPD ear cups of equal shape and thickness, and the protected and unprotected A-weighted sound pressure level (SPL) was measured in continuous and impulse noise environments >80 dBA using a JOLENE manikin. These data were evaluated for paired differences between the protected and unprotected mean SPL, and OE protected and FRPC protected mean SPL and indicates that OE thermoplastic CAHPDs provide greater sound attenuation of continuous noise >80 dBA and aramid FRPC CAHPDs provide greater sound attenuation of impulse noise >80 dBA.

In response, the California Division of Occupational Safety and Health (Cal/OSHA) performed targeted enforcement inspections at engineered stone fabrication worksites. We investigated RCS exposures and employer adherence to Cal/OSHA's RCS and respiratory protection standards from these inspections to assess ongoing risk to stone fabrication workers. Methods: We extracted employee personal air sampling results from Cal/OSHA inspection files and calculated RCS exposures. Standards require that employers continue monitoring employee RCS exposures and perform medical surveillance when exposures are at or above the action level (AL; 25 µg/m3); exposures above the permissible exposure limit (PEL; 50 µg/m3) are prohibited. We obtained RCS and respiratory protection standard violation citations from a federal database. Results: We analyzed RCS exposures for 152 employees at 47 workplaces. Thirty-eight (25%) employees had exposures above the PEL (median = 89.7 µg/m3; range = 50.7-670.7 µg/m3); 17 (11%) had exposures between the AL and PEL. Twenty-four (51%) workplaces had ≥ 1 exposure above the PEL; 7 (15%) had ≥ 1 exposure between the AL and PEL. Thirty-four (72%) workplaces were cited for ≥ 1 RCS standard violation. Twenty-seven (57%) workplaces were cited for ≥ 1 respiratory protection standard violation. Conclusions: Our investigation demonstrates widespread RCS overexposure among workers and numerous employer Cal/OSHA standard violation citations. More enforcement and educational efforts could improve employer compliance with Cal/OSHA standards and inform employers and employees of the risks for RCS exposure and strategies for reducing exposure.

TY - Journal Article AU - Gargano LM AU - Garrey SK AU - Petrsoric L AU - Takemoto E AB - The September 11th World Trade Center (WTC) disaster resulted in an elevated prevalence of Post-Traumatic Stress Disorder (PTSD) among those directly exposed, yet lower than expected rates of mental health treatment seeking and high levels of reported perceived unmet mental healthcare need were observed in this population in the years following. Self-efficacy, an individual's self-perception of their ability to succeed in specific situations or accomplish a task or goal, may in part explain this discrepancy; however, little is known about its interplay with the help-seeking behaviors of disaster-exposed populations. We used WTC Health Registry data (n = 11,851) to describe the relationship between self-efficacy and three outcomes related to help-seeking behavior: (1) seeking mental health treatment, (2) perceived unmet mental health care needs, and (3) satisfaction with mental health treatment. Multinomial logistic regression models were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CI). We found a dose-response relationship between self-efficacy score and mental health help-seeking: for every one unit increase in self-efficacy score, we observed a 6% increase in the odds of having treatment 4 to 12 months ago (OR = 1.06, CI: 1.03-1.09), a 7% increase in the odds of having had treatment 1 to 2 years ago (OR = 1.07, CI: 1.04, 1.09), and a 10% increase in the odds of having sought treatment 2 or more years ago (OR = 1.10, CI: 1.08, 1.12) compared to those who had sought treatment more recently. An understanding of individual self-efficacy may help improve post-disaster mental health treatment in order to provide more tailored and helpful care.

Many community members, defined as WTC survivors by the federal government, developed lower respiratory symptoms (LRS). We previously reported the persistence of these symptoms in patients with normal spirometry despite treatment with inhaled corticosteroids and/or long-acting bronchodilators. This report expands upon our study of this group with the goal to identify molecular markers associated with exposure and heterogeneity in WTC survivors with LRS using a selected plasma biomarker approach. Samples from WTC survivors with LRS (n = 73, WTCS) and samples from healthy control participants of the NYU Bellevue Asthma Registry (NYUBAR, n = 55) were compared. WTCS provided information regarding WTC dust exposure intensity. Hierarchical clustering of the linear biomarker data identified two clusters within WTCS and two clusters within NYUBAR controls. Comparison of the WTCS clusters showed that one cluster had significantly increased levels of circulating matrix metalloproteinases (MMP1, 2, 3, 8, 12, 13), soluble inflammatory receptors (receptor for advanced glycation end-products-RAGE, Interleukin-1 receptor antagonist (IL-1RA), suppression of tumorigenicity (ST)2, triggering receptor expressed on myeloid cells (TREM)1, IL-6Ralpha, tumor necrosis factor (TNF)RI, TNFRII), and chemokines (IL-8, CC chemokine ligand-CCL17). Furthermore, this WTCS cluster was associated with WTC exposure variables, ash at work, and the participant category workers; but not with the exposure variable WTC dust cloud at 9/11. A comparison of WTC exposure categorial variables identified that chemokines (CCL17, CCL11), circulating receptors (RAGE, TREM1), MMPs (MMP3, MMP12), and vascular markers (Angiogenin, vascular cell adhesion molecule-VCAM1) significantly increased in the more exposed groups. Circulating biomarkers of remodeling and inflammation identified clusters within WTCS and were associated with WTC exposure.

Previous studies have revealed that World Trade Center (WTC) responders exposed to carcinogens have an elevated risk of some cancers. Objective: To evaluate the association between low-serum IgE levels and cancer development in WTC-exposed responders. Methods: IgE levels were measured in 1851 WTC responders after September 11, 2001. This is the first pilot study in humans comparing the odds of developing cancer in this high-risk population, between the "low-IgE" (IgE in the lowest third percentile) vs "non-low-IgE" participants. Results: A significantly higher proportion of hematologic malignancies was found in low-IgE (4/55, 7.3%) compared with non-low-IgE (26/1796, 1.5%, P < .01) responders. The proportion of solid tumors were similar in both groups (5.5% vs 11.4%, P > .05). After adjustment for relevant confounders (race, sex, age at blood draw, WTC arrival time, smoking status), the low-IgE participants had 7.81 times greater odds (95% confidence interval, 1.77-29.35) of developing hematologic cancer when compared with non-low-IgE participants. The hematologic cancers found in this cohort were leukemia (n = 1), multiple myeloma (n = 1), and lymphoma (n = 2). No statistical significance was found when estimating the odds ratio for solid tumors in relation to IgE levels. Conclusion: WTC responders with low serum IgE levels had the highest odds of developing hematologic malignancies. This hypothesis-generating study suggests that low serum IgE levels might be associated with the development of specific malignancies in at-risk individuals exposed to carcinogens. Larger, multicenter studies with adequate follow-up of individuals with different IgE levels are needed to better evaluate this relationship.

Prevalent cases at baseline (N=30) were excluded from the analysis. Results: There were 18 incident cases of NSMSDs. Greater than 33% time in forceful hand exertion doubled the rate of incident NSMSDs. Greater than 18 degrees of shoulder abduction, during forceful hand exertion, increased the rate by 55%. Confidence intervals were wide. Conclusions: Effect estimates of the relationship between forceful hand exertions and NSMSDs were consistently elevated whether measured in isolation or while in shoulder abduction. Following a larger cohort with more frequent physical examinations would improve estimates of the model.

TY - Abstract or Summary AU - Felner J AU - Hebert-Beirne J AB - Community-based participatory research ("CBPR") approaches have become increasingly popular for addressing social and structural inequities leading to health disparities in historically marginalized communities. The specifics of the CBPR process and its many challenges, however, are often not well explicated in current scholarship. Consequently, consumers of this information must infer which processes occurred and to what extent these processes yielded successful project-related outcomes, and promoted equity among community and academic research partners. As such, there is a clear need to describe the specific processes involved in CBPR and strategies employed to overcome challenges and setbacks in the research process. In this presentation, we will explicate our use of Transformative Communication Spaces ("TCS") towards the development of two community-based research collaboratives for equity and social justice in Chicago. Through vignettes from these projects - one in collaboration with residents in a Mexican immigrant enclave and the other with queer and transgender youth of color accessing social services on the city's Northside - we will highlight the ways in which TCS allowed our research collaboratives to authentically address issues of structural racism, heterosexism, cisgenderism, and health, and overcome several complex challenges. Additionally, we will explicate our use of TCS to shift power away from the academy and into the community towards the goal of achieving a truly community-based, rather than community-engaged research process.

Greater Lawndale is a racially and ethnically diverse, high hardship community in Chicago in which residents are often engaged in "precarious work" - that which is unpredictable, unsafe, and exploitative in nature. As part of a community health assessment we conducted semi-structured individual interviews with 20 key informants, identified by academic researchers and community partners based on their knowledge about how work is experienced in Greater Lawndale. Analysis was guided by content analytic procedures and intervention mapping strategies with attention to solutions emerging from the data at various levels across the social ecology (i.e., individual, interpersonal, family, employer, community, or society) and type of intervention (knowledge, behavior change, skill, build community capacity, or structural). These results show how interviews can be used within a CBPR context to ground and meaningfully inform intervention planning and development. This analysis allowed us to understand how the community conceptualizes precarious work and the solutions to overcoming it. Through this process, we identified community resources to leverage and the potential challenges in implementing a multi-level intervention. This approach demonstrates how CBPR methodologies can support the development of pragmatic and culturally acceptable, sustainable interventions that advance health equity as well as the production of research that dismantles harmful, deficit-focused narratives about low-income communities.

TY - Journal Article AU - Cleven KL AU - Goldfarb DG AU - Prezant DJ AU - Schwartz T AU - Zeig-Owens R AB - We evaluated the incidence and risk factors for COVID-19 in a prospectively followed cohort of Fire Department of the City of New York (FDNY) World Trade Center (WTC)-exposed workers, thus reducing the potential for selection bias, a limitation in published studies of hospitalized individuals. Participants were retired FDNY WTC-exposed rescue/recovery workers with ≥ 1 medical visit between 1 March 2020 and 1 August 2021. The cumulative incidence was calculated using self-reported COVID-19 diagnoses. Cox regression was performed to evaluate the association of WTC-exposure and COVID-19, adjusting for history of comorbidities, age, race, work assignment (emergency medical service providers vs. firefighter), and sex. The cumulative incidence of COVID-19 was 130 per 1000. The adjusted models showed the risk of infection was greater in those with highest WTC exposure versus less exposure (hazard ratio (HR) = 1.14 (95% CI 1.00-1.31)). Older age was associated with a lower risk of infection HR = 0.97 (95% CI 0.96-0.98). WTC-associated diseases (obstructive airways disease and interstitial lung disease) were not COVID-19 risk factors. This study is the first to show an association between WTC exposure and the risk of COVID-19. While participants are retired from FDNY work, the youngest individuals may still be in the workforce, explaining why younger age was a significant risk for COVID-19.

TY - Abstract or Summary AU - Bonney T AU - Castañeda Y AU - Conroy LM AU - Hebert-Beirne J AU - Holloway A AU - Rospenda K AU - Velonis A AB - Background: While there is evidence that workers in nonstandard employment arrangements are disproportionately exposed to recognized occupational hazards, existing studies haven't comprehensively examined associations between employment precarity and exposure to occupational hazards for these workers in the US. The aim of this study was to examine relationships between employment precarity and occupational hazards in two contiguous high socio-economic hardship neighborhoods in Chicago. Methods: Using a community-based participatory research approach, community researchers administered a community-developed survey to 489 residents of Greater Lawndale who reported current or recent employment in a job that met at least one characteristic of precarious employment (e.g. unpredictable schedule, insecure work, no living wage/benefits). Employment precarity was calculated using a modified version of the Employment Precarity Index (EPI) developed by the Poverty and Employment Precarity in Southern Ontario group. We modeled the association between employment precarity and occupational exposures using logistic regression models. Results: Using the EPI, we classified 14% of respondents' reported working arrangements as "stable/secure", 16% as "vulnerable", and 70% as "precarious". Those classified as precarious were significantly more likely than those classified as stable/secure to report exposures to dust/chemicals, noise, vibration, extreme temperatures, and heavy lifting and were significantly more likely to report fear of violence and theft at work (ORs ranged from 2.2-3.3 at p<0.01). Conclusion(s): Results highlight the importance of using community research approaches and robust measures of employment characteristics, such as the EPI, to evaluate associations between employment precarity and hazardous exposures. These results suggest that variability in employment situations and resultant relative employment precarity are important predictors of exposure to recognized occupational hazards. Findings also suggest that health inequities observed among precariously employed workers may be partly explained by increased risk for exposure to occupational hazards, which has implications for community health and should be investigated in future longitudinal research.

TY - Abstract or Summary AU - Bonney T AU - Deb N AB - Background and Objective(s): During the summer of 2018, representatives from 20 different organizations participated in a six-meeting capacity building process hosted by the University of Illinois Center for Healthy Work. Representatives included members of health organizations, including health departments, advocacy groups, and a hospital system, and labor organizations, including a union and several worker centers. Representatives of labor organizations served as technical assistance (TA) providers, which involved participating in large group presentations and small group discussions and activities. The aim of this study was to explore the role of TA, provided by representatives of labor organizations, in building the capacity of non-labor organizations to address contributors to precarious work. Methods: Semi-structured interviews were conducted with TA providers pre- and post-participation in the six-meeting process to: (1) examine TA providers' perceptions of their own roles in building the capacity of non-labor organizations to address the contributors to precarious work; and (2) to explore TA providers' motivations for participating in the process. Additional semi-structured interviews were conducted with TA recipients post-participation in the six-meeting process to examine recipients' perceptions of the role of TA. Results: Preliminary analyses suggest that perceptions of TA's role shifted from sharing content expertise to a more intensive partnership role as both TA providers and recipients found opportunities for engagement around issues of shared interest. Initial motivation for TA provider participation was their existing relationship with the university, although this shifted as TA saw opportunities for engagement with recipients beyond the six-meeting time frame. Conclusion(s): While many features of this TA-recipient relationship aligned with features described in the literature, interactions between TA providers and recipients differed substantially from typical TA-recipient engagements. This TA-recipient model facilitated engagement between organizations that had not previously worked together, potentially expanding the capacity of both groups to address contributors to precarious work.

TY - Thesis AU - Dawkins B AB - Introduction: Non-compliance with respiratory protection programs among firefighters may put them at increased risk of injury and illness from occupational exposures during fire extinguishing activities. This research aims to characterize respiratory protection practices among Florida firefighters. This information will allow better understanding of factors that are associated with non-compliance with respiratory protection guidelines. Methods: Survey questionnaire was used to characterize Florida fire departments in this cross sectional study. Four hundred and seventy-seven surveys were administered to Florida firefighters both in person and electronically to collect information regarding firefighter knowledge and participation in their respective respiratory protection programs during the past twelve months. Survey questions were developed from the model set by the National Fire Protection Association which provides standards and regulations regarding firefighter protections. Collected data were used to produce summary statistics regarding firefighter department size, coverage area, and firefighter employment type. Further data analysis used Statistical Analysis Software to compute multinomial logistic regression analysis. Results: The 477 respondents were 91% male with a mean age 39 years old (range 21-65 years). The majority of respondents, 76%, were non-smokers, 21% former smokers, and 3% current smokers. In regards to ethnicity, respondents were 77% Caucasian, 13% Hispanic, 3% African-American, and 4% other. Most respondents were career firefighters, 97%, with less than ten years of experience, 44%, working in a fire department with at least 21 firefighters, 98%. Most respondents, 80%, had a written respiratory program in place. The most cited reason for not having implemented a written respiratory program was lack of knowledge related to the program. Multinomial logistic regression analysis of departments with response areas of at least 250,000 square miles produced a statistically significant 0.44 odds ratio for having a written respiratory program as compared to those with a less than 10,000 square miles response area. Conclusion: Additional resources need to be given to Florida fire departments to ensure that all firefighters receive adequate respiratory protection in accordance with National Fire Protection Association guidelines. There is an association between fire departments with large response areas and non-compliance with respiratory protection guidelines in regards to: having a written respiratory program, the frequency of respiratory fit testing, and the frequency of medical fitness testing. This suggests that rural fire departments need additional resources to ensure fire fighters are adequately protected. Additional research should focus on why these differences exist in the rural fire departments. Respondents stating a lack of knowledge or no requirement for a written respiratory program suggest that future efforts should focus on respiratory protection education and training.

TY - Journal Article AU - Reibman J AU - Rosen R AU - Shao Y AU - Zhang Y AB - Exposure to World Trade Center (WTC) dust/fumes and traumas on 11 September 2001 has been reported as a risk factor for post-traumatic stress disorder (PTSD) and other mental/physical health symptoms in WTC-affected populations. Increased systemic inflammation and oxidative stress from the exposure and subsequent illnesses have been proposed as contributors to the underlying biological processes. Many blood-based biomarkers of systemic inflammation, including C-reactive protein (CRP), are useful for non-invasive diagnostic and monitoring of disease process, and also potential targets for therapeutic interventions. Twenty years after 9/11, however, the relationships between WTC exposure, chronic PTSD, and systemic inflammation are only beginning to be systematically investigated in the WTC-affected civilian population despite the fact that symptoms of PTSD and systemic inflammation are still common and persistent. This paper aims to address this knowledge gap, using enrollees of the WTC Environmental Health Center (EHC), a federally designated treatment and surveillance program for community members (WTC Survivors) exposed to the 9/11 terrorist attack. We conducted a mediation analysis to investigate the association between acute WTC dust cloud traumatic exposure (WDCTE) on 9/11, chronic PTSD symptoms, and levels of systemic inflammation. The data indicate that the chronic PTSD symptoms and some specific symptom clusters of PTSD significantly mediate the WDCTE on systemic inflammation, as reflected by the CRP levels. As both chronic PTSD and systemic inflammation are long-term risk factors for neurodegeneration and cognitive decline, further research on the implications of this finding is warranted.

Precarious employment (PE) is a social determinant of health (SDOH) characterized by low wages, hazardous conditions, unstable work schedules, no termination protection, and few benefits. Even before COVID-19, calls for more effective health promotion efforts to address SDOH like PE existed. Purpose: The University of Illinois at Chicago Center for Healthy Work, Healthy Communities Through Healthy Work developed the Healthy Work Collaborative (HWC) as an evidence-informed capacity building policy, systems, and environmental change (PSE) initiative. The HWC aimed to facilitate cross-sectoral partnerships between health and labor sector partners. The labor sector provided technical assistance (TA) to participants to improve their ability to address PE through PSE. Methods: This article reports findings from a mixed-methods evaluation using the Kirkpatrick training model including participants' reactions, learning, behavior, and outcomes. A pre-post survey was administered to participants (N = 21) and analyzed descriptively; 3-month post HWC interviews were conducted (N = 13) and thematically analyzed. Conclusion: Findings included positive results at all Kirkpatrick levels. Participants' reported that the HWC curriculum and delivery was valuable and well received; they demonstrated gains toward addressing PE through PSE knowledge and skills and increased or strengthened health/labor partnerships. In addition, HWC influenced participants' application of HWC concepts, and in a few cases, participants' made changes in policies and plans in their organizational settings. The HWC may serve as a model to address other SDOH through cross-sectoral PSE change.

TY - Thesis AU - Swankie W AB - Formaldehyde is a colorless gas that is found naturally in the environment. It is a popular additive in many consumer products including composite wood products. Composite wood products are engineered wood panels produced from pressing pieces, chips, particles, or fibers of wood together at high temperatures held together with a bonding agent. This bonding agent is often formaldehyde-containing resins that are known to release formaldehyde over time. This is concerning because of the carcinogenic classification of formaldehyde, the wide spread application of composite wood products, and the increasing amount of time spent in the indoor environment. In a controlled 0.53 m3 chamber, a panel of medium density fiberboard (MDF) with a surface area of 4.49 m2 was subjected to multiple temperatures to measure formaldehyde emissions. The panels were allowed to acclimate for 48 hours followed by a 72 hour sample period using passive diffusive monitors at temperatures: 26.1, 29.3, 34.1, and 38.9 degree C. The results of the study found a strong relationship (R2 = 0.9954) between the emission rate of formaldehyde from MDF and temperature. The emission rate increased 192% between 26.1 degree C and 38.9 degree C. The results of the study indicate that as temperature increases, the amount of formaldehyde emitted from a panel of MDF also increases. This results in higher airborne concentrations of formaldehyde in environments where the panels are present.

TY - Journal Article AU - Gu JK AU - Naimo MA AB - Previous research has established the role of resistance training (RT) on muscle function in adolescents, but a lack of evidence to optimize RT for enhancing muscle quality (MQ) exists. This study examined whether RT frequency is associated with MQ in a nationally representative adolescent cohort. A total of 605 adolescents (12-15 year) in NHANES were stratified based on RT frequency. MQ was calculated as combined handgrip strength divided by arm lean mass (via dual-energy X-ray absorptiometry). Analysis of covariance was adjusted for sex, race/ethnicity, and arm fat percentage; p < 0.05 was considered significant. RT frequency was associated with MQ for 2-7 day/week but not 1 day/week. When no RT was compared to 1-2 and 3-7 day/week, associations were present for 3-7 day/week but not 1-2 day/week. When comparing no RT to 1-4 and 5-7 day/week, associations existed for 5-7 day/week but not 1-4 day/week. Next, no RT was compared to 1, 2-3, and 4-7 day/week; associations were found for 4-7 day/week, while 2-3 day/week had a borderline association (p = 0.06); there were no associations for 1 day/week. Finally, no RT was compared to 1, 2, 3, 4, and 5-7 day/week; associations were present for all except 1 and 3 day/week. These prospective data suggest a minimum RT frequency of 2 day/week is associated with MQ in adolescents as indicated by the lack of differences in MQ between 1 day/week RT versus no RT.

TY - Thesis AU - O'Mara M AB - Recent occupational health studies have focused on dermal exposure at the hands, but have been unable to accurately express dose without knowing the HSA. There is no standard method to calculate HSA, though some researchers have derived HSA formulas based on dimensions from a Taiwanese population. This research paper describes a shortcut method to estimate the hand surface area (HSA) of a human hand from a two-dimensional hand tracing, and repeated a Taiwanese HSA study in order to explore the viability of its HSA formula in an American university population. A sample of nine adult men and nine adult women, each representing one third of the population percentile in hand length and hand breadth, were selected from a population within the University of South Florida in Tampa, FL. Hand length, breadth, a 2D hand tracing and a 3D light hand scan were collected from each participant. A linear regression was used to analyze the data sets and found a correlation (R=0.94) between 2D HSA and 3D HSA and slope of 2.6 (SD=0.2), with a regression equation of Y=2.6(X). A paired t-test was used to compare the Taiwanese HSA formula data against the 3D HSA. Results found that the Taiwanese data sets were significantly different from the 3D HSA (p<0.001), averaging 57 cm2 less than the 3D HSA. A jackknife analysis was implemented on the 2D HSA hand tracing data, and a paired t-test was performed between the jackknife estimate predictions and 3D HSA. Mean differences were not significantly different (p=0.97), with 0.87 cm2 difference between means. Results indicate that the USF Hand Tracing Method will provide a better estimate of HSA than the Taiwanese method, and can be used as a tool in HSA estimation.

TY - Thesis AU - Lloyd ER AB - The health effects of silica and the connection to occupational exposure has been known for years. In March of 2016, the Occupational Safety and Health Administration (OSHA) of the Department of Labor (DOL) published a new standard meant to reduce workers' exposure to silica. The standard update was set forth to further protect workers; OSHA estimates this revision will prevent more than 600 silica-related deaths each year. A key feature of the updated OSHA standard emphasizes the use of engineering controls and work practices in certain industries. Material handling of industrial sand is a known cause of silica overexposure in many industries. A novel sand coating technology designed as an engineering control has been tested to reduce worker exposure to airborne silica. This study looked at whether the airborne silica concentrations could be reduced by applying this technology. Area air samples were collected for baseline samples along with coated samples, which were analyzed for respirable dust. The percent reduction was calculated to determine if the coating was able to reduce the airborne silica concentration. This study found that the application of the coating was able to reduce the airborne silica concentration, but the reduction did not meet the benchmark of 80% as set forth for the study. Additional studies to refine application and dosage of the sand coating may result in meeting this benchmark in future studies. Study limitations include small sample size and the truncated sampling time period for some of the samples collected, along with meteorological and site conditions.

AB - This study compared exercise performance and comfort while wearing an N95 filtering facepiece respirator (N95), cloth mask, or no intervention control for source control during a maximal graded treadmill exercise test (GXT). Twelve Division 1 athletes (50% female, age = 20.1 +/- 1.2, BMI = 23.5 +/- 1.6) completed GXTs under three randomized conditions (N95, cloth mask, control). GXT duration, heart rate (HR), respiration rate (RR), transcutaneous oxygen saturation (SpO2), transcutaneous carbon dioxide (TcPCO2), rating of perceived exertion (RPE), and perceived comfort were measured. Participants ran significantly longer in control (26.06 min) versus N95 (24.20 min, p = 0.03) or cloth masks (24.06 min, p = 0.04). No differences occurred in the slope of HR or SpO2 across conditions (p > 0.05). TcPCO2 decreased faster in control (B = -0.89) versus N95 (B = 0.14, p = 0.02) or cloth masks (B = -0.26, p = 0.03). RR increased faster in control (B = 8.32) versus cloth masks (B = 6.20, p = 0.04). RPE increased faster in the N95 (B = 1.91) and cloth masks (B = 1.79) versus control (B = 1.59, p < 0.001 and p = 0.05, respectively). Facial irritation/itching/pinching was higher in the N95 versus cloth masks, but sweat/moisture buildup was lower (p < 0.05 for all). Wearing cloth masks or N95s for source control may impact exercise performance, especially at higher intensities. Significant physiological differences were observed between cloth masks and N95s compared to control, while no physiological differences were found between cloth masks and N95s; however, comfort my differ.

TY - Journal Article AU - Pronk NP AU - Spoonheim JB AB - Not all health and well-being programs are created equal. Some programs have limited options for workers to engage in, whereas others provide a rich set of options for people to choose from. Some programs enjoy support from supervisors, whereas others lack strong leadership. Comprehensive programs, defined by Healthy People 2010 as programs that include five specific components, including health education, supportive physical and social environments, integration of the worksite program into the organization's structure, linkage to related programs, and worksite screening programs, tend to generate stronger outcomes than programs that do not meet these components. Unfortunately, according to the most recent National Worksite Health Promotion Survey, only 17% of companies in the United States have health and well-being programs that are considered comprehensive or robust in design (3). Although these five components are clearly important, there are other considerations that cannot be ignored when programs are being designed for implementation at the workplace, such as compliance to regulatory requirements or the integration of evaluation and data-based improvement efforts. Our field experience at implementing comprehensive programs as well to conduct research to test programs and generate insights and learnings demonstrates that employers who robustly implement a more comprehensive set of design principles tend to achieve better health and well-being outcomes as compared with companies that implement less robust programs.
