General Description
HEXAFLUOROETHANE(76-16-4) is a colorless, odorless gas. HEXAFLUOROETHANE(76-16-4) is relatively inert. The mixture is nonflammable and nontoxic, though asphyxiation may occur because of displacement of oxygen. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
Reactivity Profile
HEXAFLUOROETHANE is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature.
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
Potential Exposure
It is used as a coolant, in dielectric
fluids; as a propellant and refrigerant.
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. If
frostbite has occurred, seek medical attention immediately;
do NOT rub the affected areas or flush them with water. In
order to prevent further tissue damage, do NOT attempt to
remove frozen clothing from frostbitten areas. If frostbite
has NOT occurred, immediately and thoroughly wash con taminated skin with soap and water.

ChEBI: Hexafluoroethane is a fluoroalkane and a fluorocarbon. It has a role as a refrigerant.
storage
Color Code- Green: General storage may be used.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-venti lated area away from metals,including aluminum, zinc, and beryllium, and from openflames or temperatures above 52℃. Procedures for thehandling, use, and storage of cylinders should be in compli-ance with OSHA 1910.101 and 1910.169， as with therecommendations of the Compressed Gas Association.
Purification Methods
Purify it for pyrolysis studies by passing through a copper vessel containing CoF3 at ca 270o, and hold for 3hours in a bottle with a heated (1300o) platinum wire. It is then fractionally distilled. [Steunenberg & Cady J Am Chem Soc 74 4165 1962, Beilstein 1 IV 132.]
