As with any chemical, dose and exposure are critically important variables to understand any potential treatment. Short-term exposure to high concentrations may result in central nervous system and cardiac effects. Long-term exposure to concentrations above those lime weighted averages recommended herein may result in liver effects. HEAL TH HAZARDS: Inhalation: Inhalation of high concentrations of vapor 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 causes increased sensitivity of the heart to adrenaline which might cause irregular heart beats and possible ventricular fibrillation or death. Long-term exposure to concentrations above those time weighted averages recommended may cause liver damage with altered enzyme levels and central nervous system depression. When used on a fire, hazardous decomposition products are formed, but typically are within safe emergency exposure limits. Eye contact: May cause irritation, tearing, or blurring of vision, which result in part due to the cooling effect of HCFC-123 evaporation. Skin contact: Evaporative cooling can result in chilling sensations or frostbite effects. Repeated exposure to the skin can result in dermatitis. Prolonged skin contact should be avoided, but short-term contact is not considered hazardous. Ingestion: Not likely to occur in industrial use. HCFC-123 is a highly volatile liquid. This material is NOT LISTED by OSHA, NTP, or IARC as a CARCINOGEN.

Hazard pictograms

Halotron® I Fire Extinguishing Agent: Caution: Contains a compressed gas. High concentrations may cause cardiac arrhythmia and central nervous system depression, and possibly asphyxiation. May produce irritating vapors during use. Use of this material in confined spaces when personnel are present is acceptable only if the volume of the space is sufficiently large, as specified on UL listed fire extinguishers containing this product and guidance contained herein. First Aid: See other section of this MSDS. Toxicity information is located in other sections of this MSDS. FORM: 11-MS-OI REV 13 DOC ID: 960118 MATERIAi.
