FLAMMABILITY LIMITS (LEL, UEL): Not Applicable 
AUTOIGNITION TEMPERATURE: Not Determined 
EXTINGUISHING MEDIA: Non-Flammable 
SPECIAL FIRE FIGHTING PROCEDURES: Ensure that the area where the fire occurred is well ventilated before re-entering. Wear protective clothing. Use water spray or fog to cool storage containers to help prevent an uncontrolled pressure release. 
UNUSUAL FIRE AND EXPLOSION HAZARDS: The concentrated agent when applied to fire can produce toxic by-products specifically hydrogen halides which can cause damage. Avoid inhalation of these materials by evacuating and ventilating the area. 

STABILITY: Stable under normal conditions. Decomposes under fire conditions. 
INCOMPATIBILITY (MATERIALS TO AVOID): Reactive with Alkali and alkaline earth metals and powdered metals such as aluminum and zinc. Avoid contact with oxidizers. 
HAZARDOUS POLYMERIZATION: ( ) will occur (X) will not occur 
HAZARDOUS DECOMPOSITION OR BY-PRODUCTS: Thermal decomposition may produce hydrogen fluoride, hydrogen chloride, and carbonyl halide.

• When using the material for prolonged periods in filling or servicing operations, PERFORM THESE ACTIVITIES IN A WELL VENTILATED AREA.
• Fire Extinguishers filled with this material should be used in enclosed areas with a net room volume of at least 140 cubic feet per pound of Halotron I in the extinguisher.

• By inhalation: Exposure may cause central nervous system effects such as dizziness, drowsiness, anesthesia, or unconsciousness. Anesthetic effects may occur at concentrations of 5000 ppm (v/v) or above. At concentrations of 20,000 ppm or higher, HCFC-123 may cause increased sensitivity of the heart to adrenaline which might cause irregular heart beats and possibly ventricular fibrillation or death.
• To the Eyes: Irritation and tearing may result from the cooling effect of HCFC-123 evaporation to dissolve fats, contact should be avoided.
• To the Skin: Evaporative cooling can result in chilling sensations or frost bite efects. Repeated exposure to the skin can result in dermatitis. Due to the ability of GCFC-123 to dissolve fats, contact should be avoided.
• By ingestion: Not likely to occur in industrial use. Highly volatile liquid.
• LISTED AS A CARCINOGEN: ( ) YES (X ) NO

• Workplace environmental Exposure Level, WEEL (AIHA) (8 hrs): 50 ppm (v/v), based recommended on the primary component (HCFC-123).

• For 2,2-dichloro-1,1,1-trifluoroethane (CAS #306-83-2):
  LC₅₀ (4 hr.): 3.2% (32,000 ppm), (Inhalation) 
      Oral Approximate Lethal Dose (ALD): 9g/kg (body weight) 
      Cardiotoxic LOAEL (Lowest Observed Adverse Effect Level): 2% 
      Cardiotoxic NOAEL (No Observed Adverse Effect Level): 1% 
  Toxicological testing was performed on HCFC-123 by the Program for Alternative Flourocarbon Testing (PAFT). Data from acute toxicity studies in this program demonstrated that HCFC-123 has very low toxicity by skin application or inhalation. 
• For the proprietary gas mixture in the absence of extreme temperature are primarily its ability to function as a simple asphyxiant (i.e. displace oxygen).

     Rodent studies indicate HCFC-123 is easily absorbed via inhalation.  It distributes in all organs, more so in the liver.  About 90% of inhaled HCFC-123  is eliminated via the luyngs unchanged.  The remaining amount in metabolized to trifluoroacetic acid and excreted in the urine.  Small amounts of trifluoroacetylated proteins were detected in rats. 

     HCFC-123 did not affect reproductive performance in rats or harm the unborn animals in rats or rabbits at 5000 and 10,000 ppm. 

     HCFC-123 was inactive in several test-tube gnetic damage studies except the human lymphocyte chromosome aberration assay.  HCFC-123 is also inactive in live animal genetic damage studies.   Therefore, it is not considered genotoxic. 

       RECOMMENDED FIRST AID FOR OVEREXPOSURE: 
(Use breathing apparatus if rescuing in an area with high concentration) 

    Inhalation:                 Remove person to area with fresh air. Apply artificial respiration if necessary.  
                                    Contact a physician. 
    Skin Contact:            Apply large amounts of water, contact a physician. 
    Eye Contact:             Apply large amounts of water, contact a physician. 
    Ingestion:                  Induction of vomiting may pose a hazard. Contact a physician. 

    Note to Physician:    Do not administer adrenaline or similar drugs.

• Wear protective clothing when handling a leak.
• Neoprene, PVC or PVA gloves should be worn when handling.
• Protective eyeglasses and protective shoes should be worn when handling.
• Respiratory protection is not normally needed, however, if handling in enclosed spaces where applicable exposure limits will be exceeded, a Self Contained Breathing Apparatus (SCBA) should be used.
• When using the material for prolonged periods in filling or servicing operations, PERFORM THESE ACTIVITIES IN A WELL VENTILATED AREA.

• In the event of a spill, allow for adequate ventillation, and do not re-enter an area without an SCBA until adequate ventilation is accomplished.
• For spills that might result in overexposure, evacuate the area and use protective gear and SCBA's.
• Avoid leakage into water ways because HCFC-1233 is damagingv to vegetation.
• Do not expose storage containers to fire, as uncontrolled pressure releases may result.
• The HCFC-123 vapors are heavier than air, therefore use caution when releases occur in low lying areas where concentrated vapors may accumulate.
• Recommended 1 Hr. Emergency Exposure Limit: 1000 ppm (v/v) on the same basis as above.
• Recommended 1 Min. Emergency Exposure Limit: 2500 ppm (v/v) on the same basis as above.
