the very sad thing is the FDA is so concerned with the lead tainted products coming from china ,when there is and has been a very real health threat for decades in turning a blind eye to mercury in amalgam fillings issue , I just hope that one day people in those oganazations remove the blinders and finally correct the problem ( WHAT THE F**K ARE THEY THEY THINKING)
p.s. the heating and cooling industry is slowly phasing out liquid mercury room heating thermostats because of the possability of the liquid mercury escaping from the glass tube or getting broken during installation or removal unless they are the electronic programable type, most of us have them in our homes , infact ,if you accidentally break the tube that contains mercury and it spills on the floor ,you are required by law to call an E.P.A certified hazardous material clean-up crew to remove and clean-up the area ,one thermostat contains the eqivalent of about 2 avrage size amalgam fillings ,I say again
(WHAT THE F**K IS THE A.D.A AND THE F.D.A THINKING)
