We had to wear personal H2S meters at all times in the plant and they got to be a pain, having to calibrate them every day, batteries wearing out, etc.
But I guess they're better than getting knocked down. |
The gas is "pulled" from the landfill. It is usually collected around -10 inH20. At our landfill it is closer to -25-30 inh20. Once it passes the gas blower skid, it is 4.5 psig. So around the gas skid and in the engine compartments, we have fixed sensors.
