Legally: take it to an auto electrician/aircon tech and have it de-gassed there

Illegally: look for the high pressure hose connection (looks like a tyre valve with a light blue cap) and hold the button down and vent to atmosphere. Keep your head/eyes/face away.

!!BE TOLD THOUGH, THIS IS THE ILLEGAL WAY!!

Best way............

Don't run the aircon. pump too long without gas, as there is a lubricant mixed in with the gas that keeps the pump lubricated. The pump will fail after a while without the pressure and lubricant.

The aircon pump can be left "connected" to the engine via the belt, but just don't switch the aircon on.

All gases are a chemical with various affect -
however what you refer to is the possibility of cancer due to Prolonged use of R!2 gas (old type gas replaced by R134a) which can build up in your body,was more a concern for people servicing A/C systems if they actually were aware of this............

Having it degassed professionally is the best option,but is there a reason for this?

original plan was to de gas it myself change them over and then get it re gassed by auto elec. said he'd de gas it for now and when I'm finished he come to me and re gas it therefore no damage will be done.

If the compressor isn't leaking, there's not really much point changing it, as you'll need two new HNBR O rings for the connector.
Other thing is too, change the receiver/drier (reasonably cheap from Burson's), as it probably hasn't been done in a long time - pull the front bumper for this, and do it just before evacuation/recharging.

Degas shouldn't remove too much oil, but add about 10ml or so for the receiver/drier change, as it is important to maintain the oil content.

How about you provide more detail on what's happened and your intentions.

^^^^^This doesn't say much of anything.

I have a seized auxiliary shaft in an EL sedan and a seized compressor bearing in an ef wagon. got another motor in an different el sedan from a friend. while changing motor over thought I might as well do the compressor on the ef. how hard is it change the compressor bearing.

If it's the belt pulley and not a seized clutch, all the front hardware can be taken off without regassing. The ford shop manuals give a good writeup.
