lung function test among Abrasive Blasting workers in lumut perak
International Journal of Integrated Engineering, 2019Co-Authors: Hanis Zakaria, Muhammad Faris Fauzy, Mohamad Farid Sies, S. Hassan, Norzelawati AsmuinAbstract:Abrasive Blasting process is a common process in marine industry. This process was use as main cleaning process method and normally will release fine dust that hazardous to human health. Main effect from fine dust to human health are respiratory failure such as chronic obstructive pulmonary disease (COPD). Lung function test can be used to detect any respiratory problems in human. The objective of the research to evaluate the effect of dust exposure from Abrasive Blasting to the workers. This study are conduct among workers work in dusty environment in Lumut, Perak, Malaysia. FEV1/FVC value from lung function test were evaluated to determine the severity of COPD among workers. While FEV1 prediction show restrictive pattern and use to determine any respiratory or lung problems among the workers. From the result, it does not show any COPD problem among workers. However, FEV1 show that some workers need to go for detail medical surveillance because of the result is less than 0.8. Employer and workers need to understand and know their work related risk to minimize the risk arising from their job or work conducted.

Dust Exposure Monitoring: Abrasive Blasting Dust from Cleaning Process in Marine Industry
International Journal of Integrated Engineering, 2019Co-Authors: Hanis Zakaria, Industrial, Mohamad Khairul Hafiz Mohd Katman, Mohamad Farid Sies, Norrizal Mustaffa, Norzelawati AsmuinAbstract:Abrasive Blasting is one of application that widely use in marine industry. This process is expected would release dust that believe can be harmful to human health such as cause of chronic obstructive pulmonary disease (COPD). In Malaysia, Ministry of Health report that the deadliness of COPD for men in Malaysia peaks at age 80 and above. COPD start kills men at the lowest rate at age 10-14. This study to determine the dust released from Abrasive Blasting in cleaning process and effect to human worker. This experiment was conducted using establish method which is NIOSH 0500 and NIOSH 0600 for exposure monitoring process. Sample from exposure monitoring process were analysis using XRD for determine the composition of dust release from Abrasive Blasting activity. Result from study show that level of exposure to dust release from Abrasive Blasting activity are exceed from the limit under Occupational Safety and Health (USECHH) Regulations 2000. Silica dioxide and other hazardous composition found under XRD testing

evaluation of two lead based paint removal and waste stabilization technology combinations on typical exterior surfaces
Journal of Hazardous Materials, 2001Co-Authors: Alva E Daniels, J R Kominsky, Patrick J ClarkAbstract:Abstract A study was conducted to demonstrate the effectiveness of a wet Abrasive Blasting technology to remove lead-based paint from exterior wood siding and brick substrates as well as to evaluate the effectiveness of two waste stabilization technologies to stabilize the resulting blast media (coal slag and mineral sand) paint debris thereby reducing the leachable lead content. The lead-based paint removal technology effectiveness was determined by the use of an X-ray fluorescence (XRF) spectrum analyzer (L- and K-shell). The effectiveness of the technologies to stabilize the debris was evaluated through the toxicity characteristic leaching procedure (TCLP). Wet Abrasive Blasting effectively removed the lead-based paint coating from both the wood and brick substrates to below the US Department of Housing and Urban Development Guideline (1 mg/cm2) with no minimal or no damage to the underlying substrates (P

Ergonomics of Abrasive Blasting: a comparison of high pressure water and steel shot.
Applied Ergonomics, 2005Co-Authors: Beth Rosenberg, Lu Yuan, Scott FulmerAbstract:Abstract Abrasive Blasting with silica sand has long been associated with silicosis. Alternatives to sand are being used increasingly. While NIOSH has done extensive investigations of the respiratory effects of the substitutes for sand, the ergonomic effects of the substitutes have not been examined. Too often, hazards are shifted, and technologies that might save workers’ lungs could do so at the expense of their musculoskeletal systems. Hence, the objective of this study was to examine the ergonomic effects of alternatives to sand. Multiple methods, both qualitative and quantitative, were used to yield numerous kinds of data for the analysis of exposures to Abrasive blasters. PATH, a method for quantifying ergonomic exposure in non-routine work, was combined with interviews with workers, biomechanical modeling and noise level readings to assess the ergonomics of two Abrasive Blasting operations: high-pressure water and steel shot. Advantages and disadvantages of each medium are discussed. High-pressure water was slightly less ergonomically stressful, environmentally cleaner, much quieter and less dusty that steel shot, and it was reported to be slower on those tasks where both media could be used.

state of the science review of the occupational health hazards of crystalline silica in Abrasive Blasting operations and related requirements for respiratory protection
Journal of Toxicology and Environmental Health-part B-critical Reviews, 2008Co-Authors: Amy K Madl, Ellen P Donovan, Shannon H Gaffney, Meg Mckinley, Emily Moody, John L Henshaw, Dennis J PaustenbachAbstract:Excessive exposures to airborne crystalline silica have been known for over 100 years to pose a serious health hazard. Work practices and regulatory standards advanced as the knowledge of the hazards of crystalline silica evolved. This article presents a comprehensive historical examination of the literature on exposure, health effects, and personal protective equipment related to silica and Abrasive Blasting operations over the last century. In the early 1900s, increased death rates and prevalence of pulmonary disease were observed in industries that involved dusty operations. Studies of these occupational cohorts served as the basis for the first occupational exposure limits in the 1930s. Early exposure studies in foundries revealed that Abrasive Blasting operations were particularly hazardous and provided the basis for many of the engineering control and respiratory protection requirements that are still in place today. Studies involving Abrasive blasters over the years revealed that engineering contro...

State-of-the-science review of the occupational health hazards of crystalline silica in Abrasive Blasting operations and related requirements for respiratory protection.
Journal of toxicology and environmental health. Part B Critical reviews, 2008Co-Authors: Amy K Madl, Ellen P Donovan, Shannon H Gaffney, Meg Mckinley, John L Henshaw, Emily C Moody, Dennis J PaustenbachAbstract:Excessive exposures to airborne crystalline silica have been known for over 100 years to pose a serious health hazard.

This article presents a comprehensive historical examination of the literature on exposure, health effects, and personal protective equipment related to silica and Abrasive Blasting operations over the last century. In the early 1900s, increased death rates and prevalence of pulmonary disease were observed in industries that involved dusty operations. Studies of these occupational cohorts served as the basis for the first occupational exposure limits in the 1930s. Early exposure studies in foundries revealed that Abrasive Blasting operations were particularly hazardous and provided the basis for many of the engineering control and respiratory protection requirements that are still in place today. Studies involving Abrasive blasters over the years revealed that engineering controls were often not completely effective at reducing airborne silica concentrations to a safe level; consequently, respiratory protection has always been an important component of protecting workers. During the last 15-20 yr, quantitative exposure-response modeling, experimental animal studies, and in vitro methods were used to better understand the relationship between exposure to silica and disease in the workplace. In light of Occupational Safety and Health Administration efforts to reexamine the protectiveness of the current permissible exposure limit (PEL) for crystalline silica and its focus on protecting workers who are known to still be exposed to silica in the workplace (including Abrasive blasters), this state-of-the-science review of one of the most hazardous operations involving crystalline silica should provide useful background to employers, researchers, and regulators interested in the historical evolution of the recognized occupational health hazards of crystalline silica and Abrasive Blasting operations and the related requirements for respiratory protection.
