9. PHYSICAL AND CHEMICAL PROPERTIES
Appearance: Clear, colorless liquified gas
Boiling point: -15.1°F., -26.2°C.
Vapor pressure (mmHg at 20°C.): 4270
Vapor density (air = 1): 3.6
Solubility in water: Very low
pH: Not applicable
Specific gravity: 1.22 at 20°C.
% Volatile by volume: 100
10. STABILITY AND REACTIVITY
Chemical Stability: Stable under normal conditions.
Incompatibility: Reacts with finely divided metals such as aluminum, zinc, magnesium, and
alloys containing more than 2% magnesium. Can react violently if in contact with alkali
metals and alkaline earth metals such as sodium, potassium, or barium.
Hazardous Decomposition Products: Hydrogen fluoride by thermal decomposition and
hydrolysis. Oxides of carbon and fluoride may be produced by thermal decomposition.
Conditions to Avoid: Keep away from heat, sparks, and flame. Avoid high temperatures.
Hazardous polymerization: Will not occur.
11. TOXICOLOGICAL INFORMATION
POSSIBLE HUMAN HEALTH EFFECTS:
Inhalation: High atmospheric concentrations may lead to anesthetic effects, including loss of
consciousness. Very high exposures may cause an abnormal heart rhythm and prove suddenly
fatal. Higher concentrations may cause asphyxiation due to reduced oxygen content of the
atmosphere.
Ingestion: Highly unlikely, but should this occur, freeze burns will result.
Eye contact: Liquid splashes or spray may cause freeze burns.
Skin contact: Liquid splashes or spray may cause freeze burns.
Other effects: None anticipated.
Carcinogenicity: None of the ingredients are classified as carcinogenic by IARC, ACGIH, NTP,
or OSHA.
ANIMAL DATA:
LC

: 4 hr. (inh., rat) = > 500,000 ppm
Slight eye irritation resulted from a brief spray of vapor.
The material was a slight skin irritant, but not a skin sensitizer.
The threshold for cardiac sensitization (arrhythmias) in dogs pretreated with epinephrine was an
atmosphere of 75,000 ppm. The no observed effect level (NOEL) was 50,000 ppm.
