Toxicology

This product is absorbed by the respiratory tract.

I-Acute Exposure

A-Inhalation

Excessive concentrations of this nuisance dust may cause coughing, sneezing and irritation of the nasal mucosal membranes.

B-Ingestion

Not toxic.

C-Skin Contact

Skin overexposure does not represent a health hazard.

D-Ocular Contact

There is no information available but dusts could cause mecanical irritation.

II-Chronic Exposure

Excessive doses by ingestion may cause alcalosis and hyperkaliemia.

Effects on Development

No data concerning any antenatal developmental effect has been found in the consulted documentary sources.

Carcinogenic Effects

No data concerning any carcinogenic effect has been found in the consulted documentary sources.

Mutagenic Effects

No data concerning any mutagenic in vivo or in vitro effect on cells of mammals has been found in the consulted documentary sources.

First Aid

I-Inhalation

Move the worker to fresh air. Seek medical care if the individual presents respiratory problems.

II-Ingestion

If large amounts are ingested, give water to drink and seek medical advice.

III-Skin Contact

Copiously wash the affected area with water. Ask for medical advice if irritation develops.

IV-Ocular Contact

Copiously wash with running water. Ask for medical advice if irritation develops.

Québec's Exposure Limit

VEMP = 10 mg/m³, as total dust containing less than 1% crystalline silica.
