10. Stability and reactivity
Reactivity
Reacts violently with strong oxidants, nitrites, inorganic chlorides, chlorites and perchlorates
causing fire and explosion hazard.
Chemical stability
Stable under normal temperature conditions and recommended use.
Possibility of hazardous
reactions
Polymerization will not occur.
Conditions to avoid
Heat, flames and sparks.
Incompatible materials
Strong oxidizing agents. Strong acids. Halogens.
Hazardous decomposition
products
Carbon oxides. Hydrocarbons.
11. Toxicological information
Information on likely routes of exposure
Ingestion
Not likely, due to the form of the product.
Inhalation
High concentrations: Suffocation (asphyxiant) hazard - if allowed to accumulate to concentrations
that reduce oxygen below safe breathing levels. Breathing of high concentrations may cause
dizziness, light-headedness, headache, nausea and loss of coordination. Continued inhalation
ma
y
result in unconsciousness.
Skin contact
Contact with liquefied gas may cause frostbite.
Eye contac
t
Contact with liquefied gas may cause frostbite.
Symptoms related to the
physical, chemical and
toxicological characteristics
Exposure to rapidly expanding gas or vaporizing liquid may cause frostbite ("cold burn"). Very
high exposure can cause suffocation from lack of oxygen. May cause drowsiness or dizziness.
Information on toxicological effects
Acute toxicity
High concentration: Suffocation (asphyxiant) hazard - if allowed to accumulate to concentrations
that reduce oxygen below safe breathing levels.
