Protective Measures

Air pollution emissions are released from both natural and anthropogenic sources. During the environment pollution researching and monitoring the special attention should be paid to the construction operations, since during the construction processes many pollutants are released, especially fine dust particles, which are harmful to the health of construction workers and the population living near the construction site. The construction of any object in urban terrain has bad influence not only on the nearby buildings and city infrastructure, but on the existing environment of urban areas. The identification of the important pollution sources that contribute to ambient concentrations of pollutants is essential for developing an effective air quality management plan during building construction. Particular attention should be paid to emissions of fine particles during technological processes of construction with a special degree of dust emission. Control and regulation of the dynamic state of dispersed systems released during technological construction processes using a number of protective measures will reduce emissions of pollutants into the air. The objects of this research were the construction site and residential buildings of a large residential complex «Ekaterininskiy» located in Rostov-on-Don. The obtained measurement data as a result of this type of environmental monitoring showed the level of atmospheric air pollution from the construction industry using the example of the construction of the residential complex “Ekaterininskiy” in Rostov-onDon. After analyzing the situation with dust pollution the protective measures were suggested.

Introduction. The Russian aluminum industry is one of the world’s leading producers of aluminum. At the same time, the features of aluminum production technology contribute to the formation of unfavorable working conditions and increased risk to the health of workers. In this regard, an urgent but insufficiently studied issue in the production of aluminum is the assessment of occupational risks that establish the likelihood of health disorders in workers. Material and methods. The basis of the assessment of occupational risks was the existing regulatory documents (Guidelines) issued by the Federal Center for Hygiene and Epidemiology of Russian Consumer Health and Epidemiology. Existing methodical recommendations and medical technologies were used to calculate occupational risks and allowable working time (experience) under the chemical factor. The values of the annual volume of the air inhaled by the individual of the production environment and the average annual concentrations of toxicants, determined in the air of the working zone of the employees of the main occupational groups, were used. Occupational risk calculations were carried out over a period of 25 years. The total risk assessment for individual occupational groups was conducted under the probability (risk) rule calculated for individual chemicals. Results. Studies have found the average annual concentrations of harmful substances in the air of the working area over the past 5 years to be significantly lower when using the upgraded electrolysis technology (UET) compared to the traditional technology of self-burning anodes (SBA). The exception was hydrofluoride, whose concentrations did not depend on the technologies used, exceeding the MPC by 1.7 - 3.0 times. The total health risk for employees of the main occupations over a period of 25 years was in the range of 7.2 to 22.1% when using SBA, which is almost 2 times higher than when using UET (from 3.7 to 11.6 %). The highest levels of risk were observed in the group of workers using SBA and operators of electrolysis baths with UET, and the lowest - in the crane operators using both technologies. Conclusion. The use of indices of occupational risk and acceptable working hours under the influence of adverse production factors allows identifying a contingent of employees with an increased level of exposure to occupational hazards. Based on the obtained data, it is possible to predict the levels of occupational morbidity and evaluate the effectiveness of measures to improve working conditions, which plays an important role in managing occupational risk.

Safety Knowledge

A primary cause of occupational accidents is on-site workers not having proper or even adequate safety knowledge and awareness, leading to them failing to employ safety measures, equipment, or behavior to protect themselves. The complexity of construction projects and changes in organizational personnel complicate the safety knowledge transfer process. Therefore, to reduce occupational accidents in the construction industry, this study explored the on-site safety knowledge transfer process as well as its relationship with a safe working environment; it did this to understand the associations between various constructs in the process, which could be used as a reference for management personnel to promote on-site safety education and behaviors. This would allow safety knowledge to be learned and practiced by on-site workers, changing their unsafe behaviors and creating a safe on-site work environment. This study used structural equation modeling to empirically study the relationship between various constructs during safety knowledge transfer on a construction site. The results revealed that an excellent safety knowledge transfer environment can lead to favorable safety behavior as well as safety knowledge application and inspiration of on-site workers, which would affect their safety behaviors. More satisfactory safety behaviors of on-site workers could produce a safer working environment on the construction site. Moreover, although safety application and inspiration do not directly affect the safety of a work environment, they do so indirectly through safety behaviors.

Production Factors

The use of modern thermal insulation materials in construction is one of the additional sources of harmful production factors and also lead to the formation of fine dust. To date, the risk of loss of health of workers in the construction industry in contact with mineral wool is little studied. To reduce the risk of health of workers in the construction industry, it is necessary to give a comprehensive assessment of harmful factors of the production environment when using mineral wool in the technological process and justify measures to improve working conditions. The paper provides information on a widely used in the construction industry insulation material - mineral wool. Its chemical composition is given. The main unfavorable factors of the working environment are revealed. In the construction industry, one of the most pronounced harmful production factors is the formation and release of dust, which is an aerosol of predominantly fibrogenic action. The development of the construction industry, the introduction of new insulation materials in the construction of industrial buildings, installations and structures, as well as residential and public buildings lead to new, insufficiently studied factors of the production environment that affect the health of workers and may increase the risk of health loss. To date, information on the effects of mineral wool on the body of workers and the toxicological characteristics of different types of mineral wool are fragmentary. The chemical composition of the dust determines the nature and severity of the adverse effects of dust. The dispersion composition of the dust determines the depth of penetration of particles into the respiratory organs of workers. The stability of dust particles in the air of the working area, their concentration, shape and duration of exposure determine the dust load and the risk to the health of workers. Dust particles can sorb on their surface other pollutants, which both in the complex and in isolation pollute the air of the working area and have an adverse effect on workers. An important criterion for the safety of mineral wool under inhalation is the dispersion of the dust formed. It is generally accepted that the most dangerous mineral wool dust with a dispersion of 3 microns or less.

Fine aluminum dust pollution in the polishing process was detected during a field survey. To obtain a fundamental understanding of the airflow patterns and the fine dust dispersion characteristics during a polishing process, computational fluid dynamics simulations were first performed to analyze the data collected in field measurements. The inappropriate ventilation arrangement and lack of effective dust control measures were identified as the main reasons for the high dust exposure levels (in excess of 1000 μg/m3). Simulation results showed that inhalable dust particles (PM10) could be significantly diluted at the operator’s breathing level by adding a supply air inlet above the operating area. Moreover, dry dust collection systems create a risk of aluminum dust explosion accidents. An innovative design of wet dust removal system which could mitigate the occurrence of dust explosions was proposed and then implemented on site. An independent field dust assessment showed that a reduction of fine dust particles up to 95% in the worker’s breathing area and the fine dust in the vents was reduced to 80%. Therefore, the proposed strategies are implemented immediately to address the combustible dust in the polishing working environment and can provide guidance for operators.
