Fire
and Explosion Hazards: Flammable. Cylinders are equipped with temperature and
pressure relief devices but still may rupture under fire conditions. Use water
spray to cool cylinders and tanks.
Extinguishing media: water spray, water fog, dry chemical.
Special
fire Fighting Procedures: Keep container cool with water spray. If gas exiting container ignites, stop flow of gas. Do not
put out the fire unless leak can be stopped immediately. Self-contained
breathing apparatus (SCBA) is required if containers rupture and contents are
released under fire conditions.
National
Fire Protection Association (NFPA 30B): Level 1 Aerosols (lowest flammability
rating)
Consumer
Products Safety Commission (CPSC 1500.3(c)(6).16CFR):
Not Flammable.
Potential
Health Effects: Inhalation of high
concentrations of vapor is harmful and may cause heart irregularities,
unconsciousness, or death. Intentional misuse or deliberate inhalation may
cause death without warning. Vapor reduces oxygen available for breathing and
is heavier than air. Liquid contact can cause frostbite.
Human
Health Effects: Contact with the liquid
may cause frostbite. Overexposure by inhalation may include nonspecific
discomfort, such as nausea, headache, or weakness; or temporary nervous system
depression with anesthetic effects such as dizziness, headache, confusion, incoordination and loss of consciousness. Higher exposures
(>20%) may cause temporary lung irritation effects with cough, discomfort,
difficulty breathing or shortness of breath; or temporary alteration of the
heart's electrical activity with irregular pulse, palpitations, or inadequate
circulation, abnormal kidney function as detected by laboratory tests. Gross
overexposure may be fatal.
Individuals
with preexisting diseases of the central nervous or cardiovascular system may
have increased susceptibly to the toxicity of excessive exposures.
First
Aid
Eyes:
Immediately flush eyes with large amounts of water for at least 15 minutes
while holding the eyelids open. Get prompt medical attention.
Skin:
Immediately remove contaminated clothing; wash skin with large amounts of water
for at least 15 minutes. Treat for frostbite with gentle warming affected area
if necessary. Get prompt medical attention.
Inhalation:
Move victim to fresh air and restore breathing if necessary. Stay with victim
until arrival of emergency medical personnel.
Ingestion:
Ingestion is not considered a potential route of exposure.
Instability:
Stable, however, avoid open flames and high temperatures.
Incompatibility:
Incompatible with alkaline or alkaline earth metals.
Polymerization:
Polymerization will not occur.
The
compound is untested for skin or eye irritation, and for animal sensitization.
Effects in animals from single, high exposure by inhalation include labored
breathing, lung irritation, lethargy, incoordination,
and loss of consciousness. Cardiac sensitization occurred in dogs exposed to a
concentration of 150,000 ppm in air and given an
intravenous epinephrine challenge. Effects of repeated
exposure include increased urinary fluorides, reduced kidney weight and
reversible kidney changes. The effects of a single, high oral dose include
weight loss and lethargy.
Tests
in animals demonstrate no carcinogenic activity or developmental effects. Tests
in animals for reproductive effects have not been performed. This compound does
not produce genetic damage in bacterial cell cultures but has not been tested
in animals.
