Sorry to be pedantic.
Re Safetycom, I agree with Phoning first, some places use Safetycom and others don't. We use it.
It's pilots that use it, not aerodromes.
One problem is that many people don't put the airfield name at the beginning and end. So you get a call G-XX downwind for yy and you have no idea where they are.
RTFM.
