How did I not check in September?
Who follows the news with the accident (namely an accident, and not an incident) deposit. Alabushina, reads that air monitoring in with. Gluebow. The device is installed in 2013. After the emission of hydrogen sulfide at the Bayandynsky field (Lukoil did not recognize anything then, but as a result he installed a sulfur factory)

On May 28, 2013, in the morning, the inhabitants of the Scheliabozh literally suffocated from the smell of hydrogen sulfide - due to the next emission in the Bayandysky deposit. The smell penetrated the rooms, it was impossible to breathe. On this day, schoolchildren were supposed to take the exam (exam). The school principal announced the smell in the education department, in the Office for Civil Defense and Emergencies. From there, schoolchildren were advised to put on cotton pads
Then Lukoil “gave” the villagers this device.
It is installed in a Scheliabozh school, on the second floor, a sensor on the street.
After 2013, the residents repeatedly complained about the malaise and smell of hydrogen sulfide and associated this with emissions of yellow smoke into the “bandy”.
After the wells were worn out at the field. Alabushin. Periodically and from there observed emissions.
But the “air monitoring” subsequently carried out (well, just as everything is dissipated) showed the absence of an excess of MPC.
And the device is silent at school. Well, in fact, why is he silent?
Our supporter-consultant for the third day explains to me about different MPCs. Everything fell into place today, when I showed him a photo of the device.
Pictures of September 2016.

I will increase pieces:


Pay attention to the MPC in the instructions.
Hu and summarize:
The device is designed to measure concentration in the working area (that is, where people are short -term to do work)
MPC of the content of hydrogen sulfide for the working area is 10 mg/m. Kub
For populated places, another standard of GN 2.1.6.1338-03 The maximum permissible concentrations (MPC) of pollutants in the atmospheric air of populated areas
MPC on hydrogen sulfide here 0.008 mg/m. Kub
With a simple division, we get 10/0.008 = 1250
That is, the device in the Scheliabozh secondary school will give a danger signal if 1250 times a MPC of the content of hydrogen sulfide for populated places.
The calculation, made on the basis of a publicly accessible methodology for the calculation of emissions of harmful substances into the atmosphere during the free burning of oil and oil products OND86, taking into account the scattering of pollutants, it was established that the concentration of the Slovybozh, the gap in the air of the settlement can be 7.64 MAC (as of 15.04.2017)
Where will the device take the remaining 1242.36 MPC?
