Relationship Between Occupational Risk and Personal Protective Equipment on the Example of Ferroalloy Production

The article presents a draft unified classification of harmful and/or hazardous factors of working conditions for subsequent identification and assessment of any possible occupational risks of employees of various types of economic activity within the framework of the implementation of a risk-based approach in the organization of labor protection at enterprises. In total, 134 harmful and/or dangerous factors present in the production environment and work processes were identified, which were divided into six main groups: physical, chemical, biological, mechanical, psychophysiological, and general industrial pollution. A five-level classification of the main harmful and/or dangerous factors of the production environment and the labor process and their subspecies is proposed. The largest group consists of physical factors, such as industrial noise, vibration, various types of radiation, lighting conditions at enterprises, exposure to electric current and electric arc, the threat of fire or explosion, as well as climate and microclimate conditions and aerosol composition of the air. The conducted research and the creation of a detailed classification of possible harmful and dangerous effects on employees of enterprises formed the basis of a new concept of providing personal protective equipment against harmful factors of production in the Republic of Kazakhstan.

“…During the research, it was found that the noise levels at workplaces (chargers, smelters, crane operators, senior melting operators, and furnace operators) did not comply with regulatory values, exceeding the permissible level by 5-9 dB. The assessment of occupational risk showed that for each of the investigated professions, the production risk was rated as 3, indicating a moderate risk level -labor conditions class 3.1 [23].…”

The article explores the economic context of ensuring safe work and the selection of personal protective equipment (PPE) based on the dust factor. Taking into account measurements of production factors at workplaces, using the example of ferroalloy production at the Taraz Metallurgical Plant (Republic of Kazakhstan), it has been determined that the levels of general industrial dust found at certain workplaces (crusher operator, raw material reception and crushing section supervisor, charger, miner, smelter, senior master of the sinter preparation department) significantly exceed the established norms of 4 mg/m³ . As a result of the research, the working conditions of the main occupational groups in ferroalloy production are assessed as harmful and hazardous -Class 3, Degree I. Recommendations are provided for the implementation of a riskoriented approach in ensuring personal protective equipment, as well as the application of a different mechanism for determining the insurance tariff rate based on the class of professional risk, determined by the type of economic activity. This takes into account a new integrated differentiated indicator -professional risk at each workplace.

“…The actual state of working conditions at the workplace was determined based on the assessment of the class and degree of harmfulness and danger of the factors of the working environment and work process, as well as the equipment of workers with personal protective equipment (PPE) [17].…”

Provision of Personal Protection Equipment, According to the Risk of Exposure to Harmful Industrial Factors during Copper-Polymetallic Ore Mining

The article addresses the issue of providing personal protective equipment, taking into account the risk of exposure to harmful factors of production during the extraction of copper ore in ore deposits located at great depths, i.e., underground mining. The working conditions of miners are characterized by a complex of harmful production factors, which include, above all, high dust and gas pollution of the air and a heated microclimate. The investigation revealed that workers in underground mines are exposed to the harmful effects of chemical factors. The evaluation of working conditions based on microclimatic factors showed an excess of air temperature (4-12 times) and relative humidity (3-10 times) in the workplace. Mathematical data processing has shown that the distribution of dangerous and harmful factors is subject to polynomial dependence. Mathematical data processing showed that the distribution of hazardous and harmful factors is subject to polynomial dependence. Increased air temperatures at a number of production sites, air pollution with dust and gases require a revision of the list of personal protective equipment, depending on the class of working conditions, taking into account the established standards for output. The authors provide recommendations for the introduction of a new range of personal protective equipment, depending on the presence and degree of exposure to harmful factors of production.
