The list of tasks for each step

To receive practical skills in TPES method at each stage of the student is offered a choice of 7 options, consisting of two "steps" depending on the amount. Each "step" is measured at the point assessment according to said control information to the examiner.

Stage 1

Option number 1

In Almaty in December at CHP-1 and 2 fuel oil and coal are burned. In the air marked trails of smoke and soot, which descend to the earth's surface. Above the town discovered heavy fog, there is a temperature inversion, the absence of wind. In the atmosphere, found high concentrations of airborne dust (soot) - 1.5 mg / m3 (MAC - 0.05), carbon monoxide - 5.4 mg / m3 (MAC - 3.0), sulfur dioxide - 0.5 mg / m3 (MAC - 0.05), sulfuric acid - 0.15 (MPC - 0.1). Hazard Class: dust - 3, CO - 4, SO2 - 3, H2SO4 - 2.

1. What are the sources of pollution are present?

2. Preventive measures for air protection.

Time - 5 minutes.

The maximum score on the stage - 6

Stage 1

Option number 2

In the area of non-ferrous metals within a radius of 1.5-2.0 km. From lead-zinc plant and 0.5 km - CHP atmosphere polluted by carbon monoxide - 5.0 mg / m3 (MAC - 3.0), nitrogen dioxide - 0.4 mg / m3 (MAC - 0.04), lead - 0.004 mg / m3 (MAC -0.0003). Relative humidity was 80-85%, calm. The population complains of sore throat, irritation of the eyes, nose, itchy skin. Hazard Class: CO - 4, Pb - 1, NO2 - 2.

Option number 4

In the city of Karaganda, Abai, Sarani stockpiled large piles (piles) gangue coal industry. As a result of spontaneous combustion of waste dumps into the air is released sulfur dioxide at concentrations of 0.1 mg / m3 (MAC-0.05), hydrogen sulphide - 0.01 mg / m3 (MAC-0.008), carbon monoxide - 5.0 mg / m3 ( MPC-3.0), the products of resinous substances. The population complains of headaches, sense of smell "rotten eggs". Hazard classes: SO2 - 3, H2S - 2, CO - 4.
