TOXICOLOGICAL PROPERTIES
ROUTES OF ENTRY:
SKIN CONTACT: Contact with the rapidly evaporating liquid may cause frostbite
or cryogenic "burns".
SKIN ABSORPTION: None
EYE: None
INHALATION: Inhalation of high concentrations of vapor may cause dizziness,
disorientation, incoordination, narcosis, nausea or vomiting leading to
unconsciousness. Contact with the rapidly evaporating liquid may cause frostbite
or cryogenic "burns".
INGESTION: None
ACUTE OVER EXPOSURE EFFECTS: Relatively non-toxic, it may act as a
narcotic at high concentrations.
Frostbite effects are a change in color of the skin to gray or white possibly
followed by blistering.
CHRONIC OVER EXPOSURE EFFECTS: No irreversible effects are known
once an adequate supply of oxygen is returned (oxygen deficiency corrected).
EXPOSURE LIMITS: TWA = 1,000 molar ppm (ACGIH 1995-1996)
IRRITANCY OF PRODUCT: None
SENSITIZATION TO MATERIAL: None
CARCINOGENICITY, REPRODUCTIVE EFFECTS: None known
TERATOGENICITY, MUTAGENICITY: None known
TOXICOLOGICALLY SYNERGISTIC PRODUCTS: None
PREVENTIVE MEASURES
PERSONAL PROTECTIVE EQUIPMENT: Plastic or rubber gloves. Safety
goggles or safety glasses. Safety shoes.
SPECIFIC ENGINEERING CONTROLS: Halocarbon 12 is noncorrosive and
may be used with any common structural material. Silver and copper bearing
alloys can act as catalysts for the decomposition of halocarbon 12 at high
temperatures. Alloys containing more than 2% magnesium should not be used if
water is present.
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 cylinder 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癈. 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 HALOCARBON 12.
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED
BREATHING APPARATUS.
INHALATION: Conscious persons should be assisted to an uncontaminated
area and inhale fresh air. Unconscious persons should be moved to an
uncontaminated area, given assisted resuscitation and supplemental oxygen.
Further treatment should be symptomatic and supportive.
EYE CONTACT: Not applicable
SKIN CONTACT: Dermal Contact or Frostbite: Remove contaminated clothing
and 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.
