Hi Guys.

Just thinking out load here, but I assume these guys were experienced and were doing nothing un-usual!

So why did they blow up?

Either you guys in Oz have some demented stalker / nutter.
Or something unusual is happening.
As far as I can make out the explosions occurred when their vans were started.

How about if their vans contained This rouge R134a which is Highly explosive when it meets air having been in contact with aluminum.

Is it possible their vehicle a/c has recently been Topped up?
Because if this very scary crap was present (just like the 4 engineers killed servicing Container clip-on units.)
That would explain the big bang. Which occurred in experienced guys vehicles.

They are going to have known what propane smells like.


Just grizzlys theory guys!

But there seems to be more of this crap about, what's anyone think?
