As posted previously, I have a gas tank (long black re-fillable thing
which used to be fitted to a motor home) with a load of Propane in it.

Looking at using up the Propane providing some heating to the (large,
block built) shed.

I see

http://www.ebay.co.uk/itm/PORTABLE-G...E-HEATER-SITE-
HEATER-SPACE-WARMER-CALOR-LPG-/171718346564

which looks pretty reasonable, and not too powerful. 4.5kW should be about
right.

The description includes "FOR OUTDOOR USE ONLY" which I assume means don't
use it in domestic premises because of ventilation etc.

Wondering if it would be safe to use in a shed/workshop - and how do you
tell?

Cheers

Buy a canary. ;-)

More seriously, anything discharging all its combustion products into the
same space as yourself is always going to be a little bit dodgy but I
survived holidays in a caravan with a non vented gas fire when I was a
child.

I'd just make sure that you have some ventilation and get a carbon monoxide
alarm. Very cheap these days.

That's a radiant heater, isn't it, so perhaps intrinsically a bit less
safe than the "jet engine" type which are sometimes used in large
warehouse / factory type spaces. The domestic/caravan non vented gas
burners normally had open flames, not radiant elements. OTOH about 35
years ago there were "eye level grills" on domestic cookers which used
natural gas heating a ceramic to red heat without any special
ventilation requirements. (I'm pretty certain that Doner Kebab burners
are now always used with forced ventilation hoods).

Don't disagree with Tim that a CO alarm would be a reasonable precaution.

Once upon a time..... imagine a power station, whose 500 MW
alternators are cooled by internal circulation of hydrogen, and
liberally plastered with "No Smoking" signs. Nearby picture CEGB
security bloke, warming his cockles on just such a heater. I
didn't linger.

Didn't know about hydrogen cooling, ta for the encouragement to read a
bit (ie wikipedia :-) ) about it.

Of course the moment it stops working the alarms go off, long before yer
'canary man' with a fag blows himself up.

Before and after maintenance they are purged using CO2.

A power station which had been extended only had a regulating
valve in the hydrogen line where a shut-off valve should have
been. After some maintenance work, having been boxed up again,
the electrical kit was high-voltage tested. Enough hydrogen had
seeped past the inappropriate valve for there to be a significant
explosion.

Though to be fair, hydrogen leaking from an alternator would normally go
straight up, and turbine halls are pretty well ventilated. There don't
seem to be that many hydrogen fires or explosions given the amount of
plant using it for cooling, and normally associated with some gross
error during handling of new stocks.

Don't disagree that one sometimes saw *interesting* things in the old
days! Safety awareness has become much higher in the past 25 years or
so. I think Piper Alpha was one of the triggers.

Vapour take off - same principle as the portable red tanks, but when
fitted to the Motor Home it has a larger capacity and can be re-filled at
petrol stations with automotive Propane.

Used for gas heating and cooking and fridge.
