Components:              Material TETRAFLUOROMETHANE- (R-14) CAS Number% 75-73-0 100%

 

INHALATION: R-14  Overexposure by inhalation may include temporary central nervous system depression with such effects as dizziness, headache, confusion, incoordination, and loss of consciousness; or with gross overexposure (>20%), temporary alteration of the heart's electrical activity with irregular pulse, palpitations or inadequate circulation.

EYE/SKIN CONTACT:  R-14 May cause frostbite.

ADDITIONAL HEALTH EFFECTS: R-14 High concentrations of vapor is harmful and may cause heart irregularities, unconsciousness, or death. Intentional misuse can be fatal.  Vapor reduces oxygen available for breathing and  is heavier than air. Individuals with preexisting diseases of the central nervous or cardiovascular systems may have increased susceptibility to the toxicity of excessive exposures.

CARCINOGENICITY INFORMATION: None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen.

 

INHALATION:  Immediately remove to fresh air. Keep persons calm.  If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
SKIN CONTACT:  Treat for frostbite.  Seek medical assistance.

EYE CONTACT:  Immediately flush eyes with plenty of water.  Call a physician.
NOTES TO PHYSICIANS:  Because of possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, should be used with special caution only in situations of emergency life support.

FLAMMABLE PROPERTIES: Flash Point: Will not burn

Flammable limits in Air, % by Volume LEL: Not applicable UEL: Not applicable Autoignition: >1100°C (>2012°F)

FIRE AND EXPLOSION HAZARDS:  Cylinders are equipped with pressure and temperature relief devices but may still rupture under fire conditions.

EXTINGUISHING MEDIA:  As appropriate for combustibles in the area.

FIRE FIGHTING INSTRUCTIONS:  Use water spray or fog to cool container.  Self-contained breathing apparatus (SCBA) is required if cylinders rupture or release under fire conditions.

 

SAFEGUARDS (PERSONNEL): NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean-up.  Use appropriate  PERSONAL PROTECTIVE EQUIPMENT during clean-up.  Ventilate area - especially low places where heavy vapors might collect.  Remove open flames. For large releases, wear self-contained breathing apparatus (SCBA).

 

HANDLING (PERSONNEL):  Avoid breathing vapors and contact with eyes and skin.  Use with sufficient ventilation to keep employee exposure below recommended limits.

STORAGE:  Store in clean, dry area.  Do not heat above 52°C (125°F).

 

ENGINEERING CONTROLS:  Normal ventilation for standard manufacturing procedures is generally adequate.  Local exhaust should be used when large amounts are released.  Mechanical ventilation should be used in low places.

PERSONAL PROTECTIVE EQUIPMENT:  Lined neoprene gloves should be used when transferring gas.  Under normal manufacturing conditions no respiratory protection is required when using this product.  Self-contained breathing apparatus (SCBA)

CHEMICAL STABILITY:  Material is stable.  However, avoid open flames and high temperatures. INCOMPATIBILITY WITH OTHER MATERIALS:  Incompatible with alkali or alkaline earth metals – powdered A1, Zn, Be, etc.

DECOMPOSITION:  Decomposes at high temperatures (open flames, glowing metal surface, etc.) forming hydrofluoric acid. POLYMERIZATION:  Polymerization will not occur.

 

ANIMAL DATA: R-14

INHALATION 15 minute ALC:  895,000 ppm in rats.  Effects observed in animals from exposure by inhalation to concentrations of >89%, v/v include central nervous system depression and death. Exposure by inhalation at concentrations as high as 22.4% resulted in no observed adverse effects.  No animal test reports are available to define carcinogenic, mutagenic, embryotoxic, or reproductive hazards.

 

WASTE DISPOSAL: Comply with Federal, State, and Local regulations. Reclaim by distillation or remove to permitted waste disposal facility.
