TOXICOLOGICAL INFORMATION
ACUTE TOXICITY
-
Inhalation
Inhalation of high concentrations of vapour may cause the following:
Headache, drowsiness and dizziness.
As with other volatile halogenated aliphatic components, the product can cause the
following due to vapour accumulation and/or inhalation of large quantities:
Loss of consciousness and cardiac disorders aggravated by stress and lack of oxygen:
Life threatening.
Experimental in animals: (studies on the constituents of the product).
Practically not harmful if inhaled.
No death occurred in rats given 500 000 ppm / 4h.
