Never dealt with the care range of refrigerants, looks like we will be dealing with small amounts. Gonna look at the BOC course...

Main difference in procedure as opposed to our beloved normal refrigerants ;)

All input appreciated

Been doing r290 and r600 for a bit now, main thing is weighing back in or buying really accurate gauges due to low pressures. From what we were told in f-gas course up to 150g is allowed to be released safely and foster have started putting majority of cabinets with a max of 150g.

First thing is to get yourself a combustible gas leak detector from a plumbers merchant.

No smoking etc., a good purge out with N2 prior to any brazing.

No loose electrical bits either.

Deal with it as you would when using petrol or BBQ gas, as that is what you are dealing with, just much cleaner and drier!

Ensure your equipment is in good sound leak free shape, purge well with N2, and keep a clean job site, and keep fire extinguisher at hands reach (We all should have this any ways)

Hi, would anyone know if there is anyone could deal with calls on R290 in the Northampton/Leicester area ? (small stuff)

The course lasts about half a day and covers all the safety
aspects to do with HC's.

The main safety fact you will learn is the Lower flammability level
and the practical limit, which are the levels of concentrations
of the stuff in a room before it becomes flammable.

Unbrazeing components could cause problems so there is a procedure
to follow that reduces the risk of fire to almost nil.

I actually set fire to the gas that vents through the gauges
when I demonstrate the procedure, just to show how safe the
stuff is.

Do the course and don't worry, it is just a refrigerant at the
end of the day.

Good course! Cheers for today! Rep points will be added when i'm allowed to spread them out again!

Starting to have doubts about the safety of hcs, coming across more and more stories of exploding fridges on the web and these are only domestics with 40 to 60 gram charge.Problem seems to be leaking joints behind the insulation leaking into the box at night when the concentration can reach the flammibility level.The damage in one of the photos was quite severe.

Require all controls to be sealed or solid state. The whole problem is no different to the use of highly flammable lithium batteries in consumer electronics.

up to 150 gr lets put that on side for re-forum....its safe to released as long mix air(CONTAIN OXYGEN) and our hydrocarbon wont become flameable mix ...we are talking about closed spaces...when outside story is slightly diferent...
