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 toxicity
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 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).
Carcinogenicity
No evidence of carcinogenic potential exists (6).
Reproductive toxicity
No evidence of reproductive toxicity exists (2).
Specific target organ toxicity -
single exposure
Not toxic to lung tissue.
Specific target organ toxicity -
repeated exposure
Not toxic to lung tissue (6).
Aspiration hazard
Due to the physical form of the product it is not an aspiration hazard.
Further information
Pre-existing skin and respiratory conditions including dermatitis, asthma and chronic lung disease
might be aggravated by exposure.
