Dust Control Usage: Strategic Technology Interventions
An intervention to improve adoption of dust control technology is designed, implemented and evaluated using three theoretical frameworks: the Health Belief Model (HBM), Diffusion of Innovation, and the Technology Acceptance Model. A quasi-experimental design (pretest-posttest, with control group) …

Industry Usage, Stakeholder Perceptions, and Usability Characteristics of Hazard Controls Leading to the Development of a Design Process and Taxonomy for Large Handheld Powered Equipment.
… to better understand the current status of the industry and create a design process and taxonomy. Study 1 assessed current industry usage of dust control technologies and stakeholder perceptions in the concrete and masonry trades. Study 2 was similar but assessed emission control technologies in …

Integrated impact analysis of yellow-dust storms : a regional case study in China
The dust storm is a meteorological event that is caused by strong winds and proceeds from arid and semi-arid regions, transporting a thick cloud of fine sediments. In China, the sediments of dust storms mainly come from the desert and thus are called "yellow-dust storms." Although these storms can …

Silicosis among Cape gemstone workers : tigers' eye pneumoconiosis
… particularly in small, poorly regulated industries. A case series is described of six workers who developed silicosis whilst involved in the processing of semi-precious gem stones. They had been employed as stone sculptors in lapidaries where they processed tigers' eye, rose quartz, …

The study of occupational risk factors and interventions for baker's allergy and asthma among supermarket bakery workers
… employed a group-randomised design to evaluate dust control measures. Results: Prevalence of probable occupational asthma (POA, 13%) was higher than atopic (AA, 6%), non-atopic (NAA, 6%) and work-aggravated asthma (WAA, 3%). Sensitisation to flour allergens was a major determinant of elevated …

Vibration Enhanced Flooded Bed Dust Scrubber with Liquid-Coated Mesh Screen
Respirable coal mine dust (RCMD) is one of the biggest occupational health hazards. Dusty mining environments can cause life-threatening respiratory health problems for coal miners known as black lung. Over the last 20 years, the flooded bed dust scrubber (FBS) has been employed as an integral …

Effects of Dust Controls and Dust Sources on Respirable Coal Mine Dust Characteristics
Respirable coal mine dust (RCMD) continues to pose serious health hazards to workers. Over the past few decades, new regulations, monitoring technologies, and improved dust controls have emerged, and all are based on the presumption that limiting RCMD on the basis of mass will effectively mitigate …
