11. Toxicological information
Information on likely routes of exposure
Ingestion
Not likely, due to the form of the product.
Inhalation
Mechanical processing may generate dust. Gypsum dust has an irritant action on mucous
membranes of the upper respiratory tract and eyes (1).
Skin contact
Under normal conditions of intended use, this material does not pose a skin hazard. Gypsum was
not found to be a skin irritant (2).
Eye contact
Mechanical processing may generate dust. Direct contact with eyes may cause temporary
irritation (1).
Symptoms related to the
physical, chemical and
toxicological characteristics
Under normal conditions of intended use, this material does not pose a risk to health.
Information on toxicological effects
Acute toxicit
y
Low hazard.
Skin corrosion/irritation
Gypsum was not found to be a skin irritant.
Serious eye damage/eye
irritation
Gypsum does not cause serious eye damage or irritation.
Respiratory or skin sensitization
Respiratory sensitization
No data available, but based on results from the skin sensitization study, calcium sulfate is not
expected to be a respiratory sensitizer.
Skin sensitization
Not a skin sensitizer (2).
Germ cell mutagenicity
No evidence of mutagenic potential exists (3,4,5).
Carcinogenicit
y
No evidence of carcinogenic potential exists (6).
