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) …

Determination of baseline data on respirable dust concentration for safety and health enhancement in selected small and medium industries in Johor
… very limited study that discussed the effects of exposures of dust and particle matters in industry at Malaysia especially respirable dust. This study was focus on the respirable dust concentration and their respirable health symptoms in selected industry. Three (3) case studies had been done as …

Analysis of rbd palm olein abrasive blasting as new metal surface cleaning method
… dirt on the surface normally will release fine dust into the environment. Water is used with abrasive media to reduce the dust release into the environment and named as wet abrasive blasting process. However, water causes corrosion to metal surface. In this study, analysis of RBD palm olein as …

Polarized Light Microscopy and Image Processing as a Near Real-time Monitoring Tool for Coal Mine Dust Monitoring
Airborne dust in coal mining environments presents a persistent occupational health hazard, with complex and heterogeneous particle compositions that complicate exposure assessment. Despite regulatory advancements, the reemergence of severe lung diseases has underscored the limitations of …

Developing an integrated preventive framework for construction workers exposed to silica dust and chemical irritants in Zambia.
Construction industry is key to the world economies in both developed and developing nations. However, construction works could bring hazards such as silica dust and chemical irritants to site personnel. Silica dust and chemical irritants are produced from activities such as demolition, drilling, …

Exploration of Respirable Dust Particles Sourced From Rock Strata in an Underground Coal Mine
… of regulatory standards for respirable coal mine dust (RCMD) concentration and crystalline silica content, and advancements in mine ventilation and dust controls led to a steady decline of occupational lung disease among US coal miners between the early 1970s and the mid-1990s. Since that time, …

Demonstration of Optical Microscopy and Image Processing to Classify Respirable Coal Mine Dust Particles
Inhalation of respirable coal mine dust (RCMD) can lead to chronic lung diseases, including coal worker’s pneumoconiosis (CWP) and more severe forms such as progressive massive fibrosis. After the Federal Coal Mine Health and Safety Act was passed in 1969, limits on exposure to respirable dust were …

Development and Implementation of an Automated SEM-EDX Routine for Characterizing Respirable Coal Mine Dust
… routine for characterization of respirable dust particles from coal mines. Respirable dust in underground coal mining environments has long been known to pose an occupational health hazard for miners. Typically following years of exposure, coal workers' pneumoconiosis (CWP) and silicosis are …

Characterising the potential health risks associated with coal dust
Coal dust is inextricably linked to the development of dust diseases. To date, the role of mineral matter in coal has been investigated for its links to pulmonary damage; however, no consensus has been reached on which characteristics are relevant to pulmonary toxicity. This study hypothesises that …
