Real meaning of Explosion Protection

It comes from the law of Ex:
– avoid it
– do not ignite it
– if it happens, have it under control
Which means:
– no Ex atmosphere
– Ex protection applied
– your last chance
If all or any of them applied:
– you and your mates stay home even tonight
– your insurance co. may have no reasons not to pay if anything still happens
– …
Ex is expensive, but best interest of all involved.
Ex personnel competency here in this case is not a piece of paper, which we shall immediately put onto wall.

But it has the meaning all have the same understanding of Ex: it shall be first Ex, then functional.
Keep up good work!
