Quarrying activities and dust emissions: a geostatistical method in risk analysis

Degan G. A., Lippiello D., Pinzari M.

Journal of KONBiN

2006

No. 1

270--277

Quarrying activities, as for their characteristics, imply a deep environmental impact and dust emissions represent one of the most important pollutant factors. The aim of the present study, is to identify, according to a geostatistical approach, a simple procedure to forecast spatial variability of dust emissions in order to evaluate occupational risks connected with airborne dust exposure.

A Method of Ergonomic Workplace Evaluation for Assessing Occupational Risks at Workplaces

Grzybowski W.

International Journal of Occupational Safety and Ergonomics

2001

Vol. 7, No. 2

223--237

The paper discusses new trends in developing and implementing methods of workplace analysis. It presents a sample method of ergonomic workplace evaluation developed at the Poznan´ University of Technology. The method is a response to the industrial sector’s demand for tools supporting occupational risk assessment. The authors also present opportunities and benefits of applying the method in occupational safety management systems, which have gained increasing popularity in recent years.

Risk Assessment in the Working Environment in Estonia

Tint P.

International Journal of Occupational Safety and Ergonomics

1998

Vol. 4, No. 2

237--248

The first step to chart hazards in the working environment in Estonia (labour force: 0.65 million) was taken by the National Board of Health Protection in the beginning of 1996. The existing chemical, physical, and biological agents in the working environment were investigated with the help of local health inspectors in all counties. An identification of hazards and workers at risk was carried out. The results of the analysis showed that 16% of Estonian industrial workers are exposed to different hazards: 20,000 persons are exposed to noise, 11,000 are working in the conditions of vibration, 10,000 are affected by unsatisfactory microclimate, 6,000 complain about long-lasting work in a compulsory posture, the overexertion of eyes'is suffered by 5,500 persons, and physical overload by 3,500 workers. In the group of chemical hazards the greatest numbers of workers are exposed to organic dust (6,500) and welding aerosols (5,400), followed by petroleum products (2,700), and oil-shale dust (4,300). The measurements of working conditions showed that an average of 30.3% of the results are above the standards. Proposals for the improvement of the situation in occupational safety and health are presented.
