Preliminary Measurement of Welding Fumes in Automotive Plants (original) (raw)

Respiratory Effects from Welding Fumes in Automotive Industries in Malaysia

Lung function and persistent symptoms among 53 welders in Plant 1 and 44 welders in Plant 2 of automotive industries in Selangor, Malaysia were investigated. Lung functions of 52 non-welders subjects working in the similar industries were also investigated. Interviews were conducted to gathered data on persistent symptoms, smoking habits and demographic data of the welders. Lung function test by using handheld spirometer were conducted for both welders and non-welders. Metal fumes samples collected from the breathing zone of the welders were analyzed by inductively coupled plasma mass spectroscopy (ICP-MS). None of the metal elements concentration was exceeding the permissible exposure limit (PEL) for both plants. However, the odds of the more than 5 years working welders to experience 'sore or dry throat' are 3.38 times higher than less than 5 years working welder in Plant 1. In addition, statistical analysis showed significant mean difference of lung functions between weld...

Development of Welding Fumes Health Index (WFHI) for Welding Workplace’s Safety and Health Assessment

Iranian journal of public health

Abstract Background: This study aimed to develop an index that can rank welding workplace that associate well with possible health risk of welders. Methods: Welding Fumes Health Index (WFHI) were developed based on data from case studies conducted in Plant 1 and Plant 2. Personal sampling of welding fumes to assess the concentration of metal constituents along with series of lung function tests was conducted. Fifteen metal constituents were investigated in each case study. Index values were derived from aggregation analysis of metal constituent concentration while significant lung functions were recognized through statistical analysis in each plant. Results: The results showed none of the metal constituent concentration was exceeding the permissible exposure limit (PEL) for all plants. However, statistical analysis showed significant mean differences of lung functions between welders and non-welders. The index was then applied to one of the welding industry (Plant 3) for verificatio...

Measuring Concentration of Welding Fumes in Respiratory Zones of Welders: An Ergo-Toxicological Approach

Welding is a critical and important operation in various industries. The operation produces poisonous fumes and gases that can cause respiratory problems towelding technicians. National Institute of Occupational Safety and Health estimates that at least 2 million workers arerecruited as welders. This makes it necessary to preserve and protect the well-being of researchers by measuring the level of fumes inhaled by researchers. A descriptive-cross sectional study was carried out in welding workshops within the Nahav and Hamadan City of Iran. In order to measure the density of welding fumes in respiratory spaces, NIOSH 7300 and 7048 were followed. The collected data were compared with NIOSH and ACGIH standards and the results were presentedin tables and diagrams. As shown by the results, out of 15 specimens taken from the respiratory system of subjects, 3 (20%) met the standards and 12 (80%) exceeded the standards. This result indicated an imperative need to find alternative processes, provide ventilation systems for research shops and welding spots, equip the workers with respiratory masks, carry out routine checkups so that their exposure to welding fumes can be reduced.

Gravimetric and analytical evaluation of welding fume in an automobile part manufacturing factory

Journal of research in health sciences, 2008

Welding is one of the most exercised industrial processes which welders are exposed to chemical and physical Hazardous agents. This study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. A total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of welding and the stacks using a high volume pump with a volumetric flow rate of 112 lit/min calibrated with a dry gas meter. The samples were collected on round 110 mm fiber glass filters, measured gravimetrically, extracted using nitric acid and analyzed with atomic absorption spectroscopy method for heavy metals including Fe, Mn, Ni, Cr3+, Cr+6, Co, and Zn. Gravimetric measuring has shown the mean values of indoor air: 1.33 mg/m3, breathing zone of the welders using coated electrodes and CO2: 7.25 mg/m3 and 6.45 mg/m3 respectively and in ventilation exhausts: 95.07 mg/m3. The mean values of Fe, Mn, and Ni were 0.8, ...

2010

Abstract: Welding is a major industrial process used for joining metals. Occupational exposure to welding fumes is a serious occupational health problem all over the world. The degree of risk to welder’s health from fumes depends on composition, concentration, and the length of exposure. The aim of this study was to investigate workers ’ welding fume exposure levels in some industries in Jeddah, Saudi Arabia. In each factory, the air in the breathing zone within 0.5 m from welders was sampled during 8-hour shifts. Total particulates, manganese, copper, and molybdenum concentrations of welding fumes were determined. Mean values of eight-hour average particulate concentrations measured during welding at the welders

ORIGINAL REPORT Pulmonary Adverse Effects of Welding Fume in Automobile Assembly Welders

2011

Welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. Many components of welding fumes can potentially affect the lung function. This study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in Iran. This historical cohort study assesses 43 male welders and 129 office workers by a questionnaire to record demographic data, smoking habits, work history and respiratory symptoms as well as lung function status by spirometry. The average pulmonary function values of welders were lower relative to controls with dose-effect relationship between work duration and pulmonary function impairment. The prevalence of chronic bronchitis was higher in welders than controls. Our findings suggest that welders are at risk for pulmonary disease.
