11 Toxicological
information
Acute toxicity:
Inhalation
: Practically non-toxic in experiments conducted on animals.
CL50/inhalation/4 hrs/on rats>500000ppm
As with other volatile aliphatic halogenated compounds, with the accumulation of vapours and/or the inhalation of large quantities, the
product can cause: loss of consciousness and heart problems aggravated by stress and lack of oxygen; risk of death.
Local effects:
Contact with skin
: Frostbite possible from splashes of liquefied gas.
Practically non-irritating for skin in experiments conducted on animals (rabbits).
Contact with the eyes:
practically non-irritating for eyes in experiments conducted on animals (rabbits).
Sensibilisation:
Contact with skin: Experim,ental for the animal:
No skin sensitizer (guinea pig).
Chronic toxicity:
Studies on animal protracted inhalation do not highlight any chronic toxic effect (rat/ years(s)/ Inhalation: 50000ppm)
Specifical effects:
Genotoxicity according experimental available data NOT Genotoxic
Cancerogenesis
: experiments on animals do not highlight carcinogen effect clearly demonstrated (rat /Inhalation – for oral
administration)
Toxicity for reproduction:
Foetal growth no toxic effect for foetal development (rat/rabbit/inhalation).
Fertility, according the available data on animal: no toxic effects on fertility (rats/inhalation)
