More than 30 % of work places at the enterprises of hydrocarbons production and transportation are characterized by harmful working conditions. One of the main factors influencing the employees of the enterprises of fuel and energy complex is noise.
Unsatisfactory state of working conditions on factor «noise in industry» has caused the need in development and introduction of new normative documents. The analysis of the new rules regulating effect of acoustic factors (noise, vibration, infrasound, ultrasound) at the workplaces according to sanitary and epidemiologic rules and norms SanPiN 2.2.4.3359—2016 is presented. The list of the new normative and technical documents in the field of protection against the increased noise developed and approved in 2015–2016 is given.
On the basis of long-term experience of successful performance of actions for noise reduction, in gas industry it is proposed to solve the problem of protection against noise by introduction of complex of actions taking into account technical capabilities and costs for their development. In practice the noise reduction of gas transmission enterprises the planning — architectural and acoustic — construction methods are used. Main ways of this group of methods: rational relative positioning of shops with different noise levels, optimization of rooms space-planning solutions, layout of the equipment and organization of professional route of maitenance considerig equipment noise characteristics, ensurig appropriate sound insulation of the enclosures; lining of walls and ceilings by sound-absorbing structures, and use of piece sound absorbers; installation of soundproof cabins, acoustic screens and shields.
Selection of specific action and its efficiency depend on working conditions: nature of technological process, noise characteristics, required noise reduction, characteristics of the room.
It is proved that in PAO Gazprom there is a scientific basis for noise reduction at work places developed by OOO Gazprom VNIIGAZ according to the requirements the SanPiN 2.2.4.3359—2016.
