The Ministry of Education and Science of the Republic of Kazakhstan Almaty University of Power Engineering and Telecommunications Department of OC &EP CGW №2 By discipline: Ecology and sustainable development Theme: “The calculation of the hazard categories of production”. Done: student of the group EE-15-1 Sharipov H. Checked: Begimbetova A.S. Almaty 2015 INTRODUCTION Currently, a sharp aggravation of the problem of environmental pollution becomes a real threat of a global ecological disaster of any society and humanity. The areas of ecological disaster has already covered more than half the territory of the CIS and Kazakhstan, sharp environmental discomfort feels the population of many cities of the country, especially the Southern and Eastern regions. All this with great urgency puts on the agenda the problems of the real protection of the environment and human labour in the Earths biosphere. Today, the consumption of natural and energy resources, water and air pollution in the long term becomes comparable with some components of the natural circulation of substances and the rate of consumption of fossil fuels today is many times greater than the rate of natural synthesis. In turn, the environment on a global scale begins to affect energy, forcing them to consider the possibility of consumption of a particular type of fuel and energy resources and seek new resources. atmosphere emission energy gas This calculation-graphic work will be considered one of the main issues in the field of environmental protection is the emission of harmful substances into the atmosphere. For example, enterprises in the composition, which includes: fur. the workshop, welding workshop, electroplating workshop, garage and boiler room, will be presented to the calculation of the hazard categories of the production departments and the enterprise as a whole. TASK: The company posted the following workshops and production facilities: Boiler, electroplating, machine shop, welding shop and garage. To determine the hazard category of production. The original data are shown in table 1.

Mechanical workshop The composition and quantity of the projected atmospheric emissions determined by calculation on the basis of the analysis workflow. In the machining of metals are dust, mist and vapors of oils and lubricating fluids, various gaseous substances. The gross emission of harmful substances is determined on the basis of standard hours of operation of the machinery. Calculation of emissions during mechanical processing is performed according to formula (1) (tonnes/year): M = 3600 x q x Т x 10-6 , (1) Where q is the specific emission of dust (g/s); T - the time machine (hours).
