Toxicology
:
This product is absorbed by the
respiratory and digestive tracts.
I-Acute Effects :
Irritation and corrosion of the skin,
the eyes, the respiratory and digestive tracts.
Eyes :
It causes ocular irritation. It causes
an irritating and caustic effect similar to that of potassium
hydroxide.
Skin :
It causes an irritating and caustic
effect similar to that of potassium hydroxide.
Ingestion :
It can cause severe irritation of the
gastro-intestinal tract with nausea, vomiting and burns. Harmful
by ingestion.
Inhalation :
It causes irritation of the respiratory
tract.
II-Chronic Effects :
No known effects.
Effects on Development :
A study of several animal species
suggests an absence of effects on antenatal development.
Effects on Reproduction
:
No data concerning the effects on
reproduction has been found in the consulted documentary sources.
Data on mother's milk: There is no data
pertaining to its excretion or detection in milk.
Cancinogenic Effects :
No data concerning a cancerogenic effect
has been found in the consulted documentary sources.
Mutagenic Effects :
Available data do not make it possible
to make an adequate evaluation of its mutagenic effect.
First aid
:
I-Ocular Contact :
Abundantly rinse the eyes with water
during at least 15 minutes and see a doctor.
II-Skin Contact :
Quickly withdraw contaminated clothing.
Rinse skin with much water. Consult a doctor.
