background and purpose: many workers are exposed to workplace hazards. many occupational diseases are preventable by personal protective devices (ppds). though many workers do not use ppds or their protection by ppds is not sufficient. this study was designed to assess the quality of ppds usage among industrial workers. materials and methods: in a cross-sectional study, 648 workers from four ma...

This study performs an analysis of steam penetration through thermal protective fabric materials. Different, multilayered fabrics were selected and tested in a laboratory-simulated exposure, their performance (SPP) was measured terms the time required to generate second-degree burns on bodies wearers. Additionally, total transmitted energy (TTTE) during testing measured. Through statistical ana...

Abstract Since the end of 2019, Corona Virus Disease 2019 (COVID-19) pandemic has led to a surge in use all kinds medical supplies, especially surgical masks. Based on microstructure and anti-virus mechanism melt-blown materials used for masks, this paper introduces research status nonwoven filter protective At same time, surface interface structure four disposable masks from different manufact...

The paper describes I-Promise, an expert system for configuration design of complex protective materials. Configuration problem of I-Promise is a part of conceptual design of complex protective materials; hence the context of conceptual design and configuration problems is briefly described before the detailed description of I-Promise, its problem domain, its design, and its application. Due to...

OBJECTIVE To explore the type and quality of handgun safety information a typical consumer would obtain from a licensed gun dealer. METHODS Semistructured, interactional on-site interviews were conducted with licensed handgun dealers in 2 metropolitan areas. A variety of dealers (gun shops, pawnshops, general merchandise stores, and sporting goods stores) were visited. Investigators posed as ...

For more permission information, see page 2. Syringe and needle prices rose modestly last year, as predicted, but are expected to decline this year, now that hospitals have progressed sufficiently in conversion to safety products. Even some of the pricier safety needles have begun to drop in price, while traditional models are continuing their previous declines, materials managers reported in t...

Nanotechnology presents the possibility of revolutionizing many aspects of our lives. People in many settings (academic, small and large industrial, and the general public in industrialized nations) are either developing or using engineered nanomaterials (ENMs) or ENM-containing products. However, our understanding of the occupational, health and safety aspects of ENMs is still in its formative...
