Promotion of alternative-sized personal protective equipment.

INTRODUCTION: With more diversity in the workforce, companies are producing PPE such as hard hats, safety glasses, coveralls, foot protection, and safety harnesses for a larger range of body shapes and sizes. However, gray literature reports suggest that barriers exist to getting alternate sized PPE from the manufacturer to the workers who need it. The purpose of this study is to determine the extent to which alternative-sized PPE is marketed. METHOD: A web-based review of seven major manufacturers of PPE was conducted to determine: (a) whether or not they offer alternative-sized products, (b) if these products are clearly labeled, and (c) if images used to display PPE are representative of a diverse workforce. RESULTS: Of the seven PPE manufacturers investigated, six had at least one product that was marketed as gender and/or size alternatives however, alternative sizes were more common for larger body types. Alternative-sized products rarely included size charts, and the models used to display PPE were overwhelmingly white males of average size. CONCLUSIONS: Despite the growing availability of alternative-sized PPE, it can be difficult to find these products, which suggests that they are rarely promoted or labeled as alternative-sized. Our study indicates that companies should expand their product lines and more aggressively market and promote these items. Guidance on how to properly fit their products would also be extremely helpful to the end-user. PRACTICAL APPLICATIONS: Manufacturers could improve the availability of alternative-sized PPE and increase their promotion of these products on their websites and in their catalogs. Individual companies and safety professionals may assist in this process by demonstrating demand for alternative-sized PPE.

Work Experiences of Latina Immigrants: A Qualitative Study.

Almost half of the Latino immigrants working in the United States are women. However, studies concerning the work experiences of Latinas are almost absent in the literature. This article reports the findings from a qualitative study using eight focus groups (n = 53) of Latina immigrant workers. The focus group transcripts were analyzed using the grounded theory approach in which themes emerge from iterative readings of the transcripts by a group of investigators. This study identified themes related to excessive workload, familiar work/unfamiliar hazards, cultural tensions, lack of health care, pregnancy, sexual harassment, and family obligations/expectations. The responses of the Latina workers in this study clearly indicated that they live within a complex web of stressors, both as workers and as women. The increased economic opportunities that come with immigration to the United States are accompanied by many opportunities for exploitation, especially if they are undocumented. It is hoped that the findings of this study will raise awareness regarding these issues and spur further work in this area.

Anaerobic treatment of vinasses by a sequentially mixed moving bed biofilm reactor.

Wine distillery wastewater, commonly called vinasses, was treated by an anaerobic moving bed biofilm reactor (AMBBR) with 32.9 litre available volume. The reactor was filled with 66% cylindrical polyethylene supports with density 0.84 g cm(-3) as a biofilm carrier. The reactor was sequentially mixed by a submerged centrifugal pump fixed to the bottom, and each mixing time just lasted 1.25 minutes. The organic loading rate (OLR) of the reactor were increased from 1.6 to 29.6 g sCOD l(-1) d(-1) (soluble chemical oxygen demands--sCOD) and hydraulic retention time (HRT) was decreased from 6.33 to 1.55 days accordingly. Soluble COD removal efficiency was 81.3-89.2% at an OLR of 29.6 g sCOD l(-1) d(-1). At the end of the experiment, 83.4% total biomass was attached on support and the specific density of support in the reactor was 0.93-1.05 g cm(-3), which increased by about 10.7-25% compared with that at the beginning of the study.
