Abstract.

Purpose:  Creation of safe and harmless productions (providing of comfort terms of labour on workplaces) is a complex task, very difficult, but is extraordinary important. It is adduction in accordance with the requirements of sanitary norms of factors of microclimate, dusty, gassed, illumination, noise, vibration etc. The purpose of work is to study sanitary and hygienic conditions by the following factors: noise, vibration, temperature, air movement speed in workshops, relative humidity, gas pollution, dustiness, and light in precast concrete plants. Methods. Methods for monitoring parameters of microclimate, noise, vibration, light and level of dust and gas. Results. As a result of inspection more than 20 enterprises of building industry, conducted researches of sanitary-hygienic terms were exposed the parameters of noise, vibration, meteorological terms, dusty and gassed. Characteristic of the key job hazards is given in the form of histogram, and measures for reducing noise parameters are proposed. The currently used technological schemes (bench technology, flow-modular technology, flow-conveyor technology and cassette technology) for the precast reinforced-concrete structure manufacturing were analyzed. The noisiest technological equipment is vibration platforms, whose noise, by intensity, exceeds sanitary norms by up to 1000%. Noise with such parameters accompanies the service personnel job during the whole working day. Scientific novelty. Characteristic of the main job hazard factors is described in the form of histogram for technological posts for manufacture of reinforced-concrete products; the, histograms are proposed to be used at enterprises. Practical significance. The proposed histograms make it possible to quickly and efficiently analyze job conditions at workplaces and respond, at right time, to the situation that is developed, in order to attest working places, if necessary. Methods are proposed for reduction noise in the construction industry.

Keywords: noise; manufacture of reinforced-concrete products; histogram, noise reduction.
