Removal.

Caution should be exercised with fluorocarbon refrigerant

gas as they can displace oxygen and thereby cause suffocation.

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 arrhythmias, as a result of exposure to

fluorocarbon refrigerant gases (freons). Such individuals

should be evaluated by local medical authorities before

working in environments where potential freon exposure may

occur.
