Hydrogen -Sulfide

[Jay Bondesen]

H2S is detectable to people in the parts per billion range and the test equipment to measure at that level is considerably more expensive. Most experts consider it hazardous in the very low parts per million range and the duration of the exposure has to be considered as well. The Civil Defense Department is supposed to be working on getting this equipment into the field. Using them requires some training and the machines need regular calibration and care in their handling to insure accuracy. And then, what level at what duration constitutes a nuisance, a hazard, or an emergency? Depends on who you believe.
