I'm not sure what it is like in the rest of Europe but in the UK
if you work with flammable gas for heating purposes then you
must be Gas Safe qualified (taken every 5 years), so plumbers,
heating engineers and gas fitters all need that "Gas Safe" qual.
In refrigeration HC gases are treated just like other refrigerants
and if you are trained and qualified to work with one then you are
trained and qualified to work with the other (the exception is Ammonia).
The training covers the issues regarding HC's flammability but does not
go into too much detail.
The suppliers do require us to hold a HC qualification before they will sell
the stuff to us but that is not strictly enforced everywhere.
As far as I know (if anyone knows different let me know) as far as I know
we have not had any real incidents where an engineer was hurt or hurt
somebody while working with HC's.
It might be because the system to date are so small that not enough of
the stuff is present to cause harm, or we are just fantastic
or maybe
we have just been lucky to date
