  • UNCONSCIOUSNESS OR DEATH.
  • INFLAMMABLE VOLATILE LIQUID WHICH MAY CAUSE EYE IRRITATION OR DRYING OF THE SKIN.
  • MAY DECOMPOSE ON CONTACT WITH FLAMES OR EXTREMELY

HOT METAL SURFACES TO PRODUCE TOXIC AND CORROSIVE PRODUCTS.

Skin contact and inhalation are expected to be the primary routes of occupational exposure to this material. Prolonged or repeated contact removes oils from the skin and may dry skin causing irritation, redness and rash. High vapor concentrations are irritating to the eyes and respiratory tract and may result in central nervous system (CNS) effects such as headache, dizziness, drowsiness and, in severe exposure, loss of consciousness and death. The dense vapor of this material may reduce the available oxygen for breathing. Prolonged exposure to an oxygen deficient atmosphere may be fatal. Inhalation may cause an increase in the sensitivity of the heart to adrenaline, which could result in irregular or rapid heartbeats. Medical conditions aggravated by exposure lo this material include heart disease or compromised heart function.

FIRST AID MEASURES

Inhalation

  • IF INHALED, remove to fresh air. If not breathing, give artificial respiration.
  • If breathing is difficult, give oxygen. Get medical attention. Do not give
  • adrenaline, epinephrin or similar drugs following exposure to this product.

Skin Contact

  • IF ON SKIN, flush the area with plenty of water. Remove contaminated clothing and shoes. Wash clothing before reuse. Get medical attention if irritation develops and persists.

Eye Contact

  • IF IN EYES, immediately flush with plenty of water for at least 15 minutes. Get medical attention.

Ingestlon

  • IF SWALLOWED, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.

FIRE AND EXPLOSION HAZARDS/FIRE FIGHTING MEASURES

FIRE FIGHTING MEASURES

Fire Fighting Instructions

Cool fire exposed containers well after the fire is out to prevent possible explosions. Fire fighters and others who may be exposed to products of combustion should wear full fire fighting turn out gear (full Bunker Gear) and elf-contained breathing apparatus (pressure demand NIOSH approved or equivalent). Firefighting equipment should be thoroughly decontaminated after use.

Fire and Explosion Hazards

May decompose on contact with flames or extremely hot metal surfaces to produce toxic and corrosive products. Some mixtures of HCFCs and/or HFCs. and air or oxygen may be combustible if pressurized and exposed to extreme heat or flame. Container may explode if heated due to resulting pressure rise.

HANDLING, STORAGE, SPILL, EXPOSURE, CONTROLS AND DISPOSAL INFORMATION

HANDLING AND STORAGE

Use Halogen leak detector or other suitable means to locate leaks or check atmosphere. Keep upwind. Evacuate enclosed spaces and disperse gas with floor-level forced-air ventilation. Exhaust vapors outdoors. Do not smoke or operate internal combustion engines. Remove flames and heating elements.

EXPOSURE CONTROLS / PERSON AL PROTECTION

Do not get in eyes, on skin or clothing. Avoid breathing vapor or mist. Keep container closed. Use only with adequate ventilation. Wash thoroughly after handling. Keep away from heat, sparks and flame. Emptied container retains vapor and product residue. Observe all labeled safeguards until container Is destroyed. Do not reuse this container. Do not cut or weld on or near this container. Although this material is stable in long-term storage in carbon steel containers, it may gradually decompose in the presence of ferric chloride. The presence of excess levels of moisture, especially as a separate layer, should be avoided since it may lead to corrosion of carbon steel and formation of ferric chloride. It is recommended that containers be raised above floor or ground during extended storage periods to prevent container corrosion due to standing water. Prior to putting a storage system into service for this product, or after maintenance, ensure that the system is dry and oxygen-free. Purging the system with dry nitrogen is recommended. In addition, containers previously exposed to hydrogen chloride (for example, from impurities in chlorinated blowing agents or solvents), should be thoroughly cleaned first. Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation if necessary to control exposure levels below airborne exposure limits (see below). If practical, use local mechanical exhaust ventilator at sources of air contamination such as open process equipment. Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available. Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin contact. Consult glove manufacturer to determine appropriate type glove material for given application. Wear face shield and chemical resistant clothing such as a rubber apron when splashing may occur. Rinse contaminated skin promptly Wash contaminated clothing and clean protective equipment before reuse. Wash skin thoroughly after handling. Avoid breathing vapor or misl. When airborne exposure limits are exceeded (see below), use NIOSH approved respiratory protection equipment appropriate to the material and/or its components. Consult respirator manufacturer to determine appropriate type equipment for given application. Observe respirator use limitations specified by NIOSH or the manufacturer. For emergency and other conditions where exposure limit may be significantly exceeded, use an approved full face positive-pressure, self-contained breathing apparatus or positive-pressure airline with auxiliary self- contained air supply.

Personal Protective Equipment

Impervious gloves and chemical splash goggles should be used when handling the liquid. Under normal manufacturing conditions, no respiratory protection is required when using this product. Self-contained breathing apparatus (SCBA) is required is a large release occurs.

DISPOSAL CONSIDERATIONS

TOXICOLOGICAL AND ECOLOGICAL INFORMATION

TOXICOLOGICAL INFORMATION

No allergic skin response was observed in guinea pigs following repeated skin exposure to this material using the maximization procedure. Inhalation of high concentrations of this material (generally exceeding 10000 ppm; produces a transient anesthetic effect in rodents. As with many other halogenated hydrocarbons, inhalation of this material, followed by intravenous injection ol epinephrine to simulate human stress reactions, resulted in heart sensitization at levels above 5000-10000 ppm in dogs and monkeys. Longer term inhalation studies of up to 13-weeks duration at concentrations of this mateial up to 20000 ppm resulted in minor changes in body weight and slight changes in blood chemistry in rats. Repeated inhalation of this mateial vapors at levels up to 15000 ppm for 16-weeks did not produce evidence of nervous system toxicity or behavioral effects in rats. Long-term inhalation (2-years) of high concentrations of this material (5000 and 20000 ppm) caused an increase in the incidence of benign, not life-threatening tumors of the testes in rats. No exposure-related effects or tumors were observed at 1500 ppm in this study. No birth defects were noted in rabbits exposed to this material by inhalation during pregnancy at levels up to 12500 ppm: signs of maternal loxicity were noted at 4200 ppm or above. No birth defects were noted in rats exposed to this material by inhalation during pregnancy at levels up to 20000 ppm; toxic effects were noted in the mothers and their offspring. In a reproduction study, reductions in litter size, total liter weight and growth rate were observed in rats exposed by inhalation to 20000 ppm of this mateial for 2-generations. Delayed sexual maturity of male offsping from parents exposed to 8000 and 20000 ppm may have been related to the lower growth rate. This material has generally produced no genetic changes in standard tests using animals (in vivo tests) and animal or bacterial cells. Metabolism studies in rats exposed by inhalation show that this material is not metabolized Avoid contact with hydrochloric acid, alkali or alkaline earth metals, finely powdered metals (aluminum, magnesium, zinc) and strong oxidizers since they may react or accelerate decomposition.

Incompatibility

Thermal decomposition products include hydrogen fluoride, hydrogen
chloride, carbon monoxide, carbon dioxide, chlorine and carbonyl halides.
