Horn button replacememt [airbag????]

I have a 94 3000GT and I have to replace the right
side horn button on the steering wheel I have the new
button. In order to replace it I will need to remove the
center cover which houses the airbag.I have never fooled
with a airbag.My question is any special precautions I sould
take? and am I in danger of setting off the airbag? any advice
would be very welcome
thanks
