PRODUCTS:
EXPLOSION DATA: Nonflammable gas
SENSITIVITY TO STATIC DISCHARGE: None
REACTIVITY DATA
CHEMICAL STABILITY: Stable
INCOMPATIBLE MATERIALS: Sulfur hexafluoride is thermically
stable up to 800掳C. Other metals
can cause slow decomposition to
SF2, S2F, SF4, and S2F10. If
oxygen is present, thionyl fluoride
compounds such as SOF2, SO2F
will be formed as well as other toxic
fluoride compounds.
CONDITIONS OF REACTIVITY: Unknown

TOXICOLOGICAL PROPERTIES
ROUTES OF ENTRY:
SKIN CONTACT: None
SKIN ABSORPTION: None
EYE: None
INHALATION: Effects of exposure to high concentrations so as to displace the
oxygen in the air necessary for life are headache, dizziness, labored breathing
and eventual unconsciousness.
INGESTION: None
ACUTE OVER EXPOSURE EFFECTS: Sulfur Hexafluoride is nontoxic, but the
liberation of a large amount in a confined area could displace the amount of
oxygen in air necessary to support life.
CHRONIC OVER EXPOSURE EFFECTS: None
EXPOSURE LIMITS: TWA = 1,000 molar ppm (ACGIH 1995-1996)
IRRITANCY OF PRODUCT: None
SENSITIZATION TO MATERIAL: None
CARCINOGENICITY, REPRODUCTIVE EFFECTS: None
TERATOGENICITY, MUTAGENICITY: None
TOXICOLOGICALLY SYNERGISTIC PRODUCTS: None
PREVENTIVE MEASURES
PERSONAL PROTECTIVE EQUIPMENT: Protective gloves. Safety goggles or
glasses. Safety shoes.
SPECIFIC ENGINEERING CONTROLS: At normal temperatures, sulfur
hexafluoride is noncorrosive and may be used with any common structural
material. At elevated temp, sulfur hexafluoride is stable in the presence of
alumimum, stainless steel, copper, brasses or silver.
LEAK AND SPILL PROCEDURES: EVACUATE ALL PERSONNEL FROM
AFFECTED AREA.
Use appropriate protective equipment. If leak is in user's equipment, be certain to
purge piping with an inert gas prior to attempting repairs. If leak is on container or
container valve, contact the closest MEGS location.
WASTE DISPOSAL: Do not attempt to dispose of waste or unused quantities.
Return in the shipping container properly labeled, with any valve outlet plugs or
caps secured and valve protection cap in place to MEGS for proper disposal. For
emergency disposal, contact the closest MEGS location.
HANDLING PROCEDURES AND EQUIPMENT: USE ONLY IN WELL-
VENTILATED AREAS.
Valve protection caps must remain in place unless container is secured with
valve outlet piped to the point of use. Do not drag, slide or roll cylinders. Use a
suitable hand truck for cylinder movement. Use a pressure reducing regulator
when connecting to lower pressure piping or systems. Do not heat cylinder by
any means to increase the discharge rate of product from the cylinder. Use a
check valve or trap in the discharge line to prevent hazardous back flow into the
cylinder. Do not tamper with (valve) safety device. Close valve after each use
and when empty.
STORAGE REQUIREMENTS: Protect cylinders from physical damage. Store in
cool, dry, well-ventilated area of non combustible construction away from heavily
trafficked areas and emergency exits. Do not allow the temperature where
cylinders are stored to exceed 52掳C. Cylinders must be stored upright and firmly
secured to prevent falling or being knocked over. Full and empty cylinders should
be segregated. Use a "first in - first out" inventory system to prevent full cylinders
being stored for excessive periods of time.
TDG CLASSIFICATION: 2.2
WHMIS CLASSIFICATION: A
SPECIAL SHIPPING INFORMATION: Always secure cylinders in an upright
position before transporting them. NEVER transport cylinders in trunks of
vehicles, enclosed vans, truck cabs or in passenger compartments. Transport
cylinders secured in open flatbed or in open pick-up type vehicles.
FIRST AID MEASURES
SPECIFIC FIRST AID PROCEDURES: PROMPT MEDICAL ATTENTION IS
MANDATORY IN ALL CASES OF OVEREXPOSURE TO SULFUR
HEXAFLUORIDE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
SELF-CONTAINED BREATHING APPARATUS.
INHALATION: Conscious persons should be assisted to an uncontaminated
area and inhale fresh air. Quick removal from the contaminated are is most
important. Unconscious persons should be moved to an uncontaminated area,
given assisted resuscitation and supplemental oxygen. Further treatment should
be symptomatic and supportive.
EYE CONTACT: Flush contaminated eye(s) with copious quantities of water.
Part eyelids to assure complete flushing. Continue for a minimum of 15 minutes.
SKIN CONTACT: Frostbite: FLUSH AFFECTED AREAS WITH LUKEWARM
WATER. DO NOT USE HOT WATER. A physician should see the patient
promptly if the cryogenic "burn" has resulted in blistering of the dermal surface or
deep tissue freezing.
