Easiest way to learn about Gas Detectors and Monitors

Which is the easiest way to learn about Gas Detectors and Monitors? Well you may think the easiest way is to go to YouTube and see if you can get to see some useful videos about it. But then that is time consuming and even after watching several of them, you can be sure that you will not know even 60% of the subject. Then what is next best? Surf the internet or visit a few LinkedIn groups? Frankly that's not the easiest way to learn. Besides on places like LinkedIn, you can never be sure that you are getting the correct information from experts. Why? Because the real experts are busy designing or selecting, installing and using Gas Monitors, not whiling away time on LinkedIn!
So the best way is to go for an online training course on Gas Monitors, which has been made by experts and used by hundreds of engineers and technicians all over the world. You can also get certified on passing the exam and get an electronic badge that shows the world that you are a pro when it comes to Gas Monitors.

Trust me, this is the easiest and best way to get trained and certified in the shortest possible time!

 Perhaps the most difficult task of any project that involves gas monitors and gas detectors is to decide on the placement of the various detectors and monitors. Even with all the new software( and all the associated bells and whistles) available now, it is more of an art than a rigid science.  Some questions that need answering before you start the job are

1. How do you estimate where the leak would likely take place? From flange joints in piping? Or from valve stems/packings? Or from sampling points? Or from reactor agitator shafts (even with all the mechanical seal stuff)?
2. Once leaked, how would the gas flow? How will the molecules move in the air? We can study gas dispersion models of leaks, but they are not accurate predictions. Would the gas flow just as the dispersion model says it should? Or will it flow in some other pattern?
3. How much would reach the detector?
4. Would the detector sense it? (Would the sensor be "alive" or already poisoned to death a long time back?

Only then can we start siting the detectors. This is of course after the technology has been selected (InfraRed or Catalytic Combustion or Semiconductor or other).
