Dear investors and friends
I had an exam for my new job on Friday. I just did not make it. but there are new opportunities. next week .
the exam is difficult and that is not for nothing. gas and vapors are dangerous.
Maybe it's good that I have to do it again. I have had to pass my driver's license several times and now I am one of the best chaffeurs. hehe. that is saying sort of. but it is more for me that I know that it will be okay.
so what do I know?
let's start with the usual air. the air that you and I breathe consists of oxygen 20.9% and if that goes up, it can cause an explosion. that only happens with a leaky gas bottle with pure oxygen. what can happen for example when welding. if it comes under 18% work is already heavier and also advised without self-breathing protection. you can see this again at confined spaces such as oil tanks.
in fire it is the vapor that burns. solids do not burn. just look at wood, they are the vapors where the fire is. for fire you need 3 things: temprature fuel and oxygen without 1 of the 3 you do not have fire.
air ratios are measured in values and much more. I will stop blogging. and save the rest for a next post. hehe be safe
