Caution should be exer-
cised with fluorocarbon
refrigerant gas (freons) as
they can displace oxygen and
thereby cause suffocation.
2.
Personnel with a history
or other evidence of cardiac
rhythm abnormalities should be
made aware of the potential
for aggravation of existing
cardiac rhythm abnormalities
or the induction of arryth-
mias, as a result of exposure
to fluorocarbon refrigerant
gases (freons).
Such indivi-
duals should be evaluated by
local medical authorities be-
fore working in environments
where potential freon exposure
may occur.
(8) Refer to figure 6-2 and charge
